Forced Expiratory Volume
Measure of the maximum amount of air that can be expelled in a given number of seconds during a FORCED VITAL CAPACITY determination . It is usually given as FEV followed by a subscript indicating the number of seconds over which the measurement is made, although it is sometimes given as a percentage of forced vital capacity.
Respiratory Function Tests
Forced Expiratory Flow Rates
Maximal Midexpiratory Flow Rate
Total Lung Capacity
The volume of air contained in the lungs at the end of a maximal inspiration. It is the equivalent to each of the following sums: VITAL CAPACITY plus RESIDUAL VOLUME; INSPIRATORY CAPACITY plus FUNCTIONAL RESIDUAL CAPACITY; TIDAL VOLUME plus INSPIRATORY RESERVE VOLUME plus functional residual capacity; or tidal volume plus inspiratory reserve volume plus EXPIRATORY RESERVE VOLUME plus residual volume.

The act of breathing with the LUNGS, consisting of INHALATION, or the taking into the lungs of the ambient air, and of EXHALATION, or the expelling of the modified air which contains more CARBON DIOXIDE than the air taken in (Blakiston's Gould Medical Dictionary, 4th ed.). This does not include tissue respiration (= OXYGEN CONSUMPTION) or cell respiration (= CELL RESPIRATION).
A quaternary ammonium parasympathomimetic agent with the muscarinic actions of ACETYLCHOLINE. It is hydrolyzed by ACETYLCHOLINESTERASE at a considerably slower rate than ACETYLCHOLINE and is more resistant to hydrolysis by nonspecific CHOLINESTERASES so that its actions are more prolonged. It is used as a parasympathomimetic bronchoconstrictor agent and as a diagnostic aid for bronchial asthma. (From Martindale, The Extra Pharmacopoeia, 30th ed, p1116)
Idiopathic Pulmonary Fibrosis
A common interstitial lung disease of unknown etiology, usually occurring between 50-70 years of age. Clinically, it is characterized by an insidious onset of breathlessness with exertion and a nonproductive cough, leading to progressive DYSPNEA. Pathological features show scant interstitial inflammation, patchy collagen fibrosis, prominent fibroblast proliferation foci, and microscopic honeycomb change.
Bronchial Provocation Tests
Lung Diseases, Interstitial
A diverse group of lung diseases that affect the lung parenchyma. They are characterized by an initial inflammation of PULMONARY ALVEOLI that extends to the interstitium and beyond leading to diffuse PULMONARY FIBROSIS. Interstitial lung diseases are classified by their etiology (known or unknown causes), and radiological-pathological features.
Plethysmography, Whole Body
A diffuse parenchymal lung disease caused by inhalation of dust and by tissue reaction to their presence. These inorganic, organic, particulate, or vaporized matters usually are inhaled by workers in their occupational environment, leading to the various forms (ASBESTOSIS; BYSSINOSIS; and others). Similar air pollution can also have deleterious effects on the general population.
Care of patients with deficiencies and abnormalities associated with the cardiopulmonary system. It includes the therapeutic use of medical gases and their administrative apparatus, environmental control systems, humidification, aerosols, ventilatory support, bronchopulmonary drainage and exercise, respiratory rehabilitation, assistance with cardiopulmonary resuscitation, and maintenance of natural, artificial, and mechanical airways.
Respiratory Physiological Phenomena
Pulmonary Gas Exchange
An autosomal recessive genetic disease of the EXOCRINE GLANDS. It is caused by mutations in the gene encoding the CYSTIC FIBROSIS TRANSMEMBRANE CONDUCTANCE REGULATOR expressed in several organs including the LUNG, the PANCREAS, the BILIARY SYSTEM, and the SWEAT GLANDS. Cystic fibrosis is characterized by epithelial secretory dysfunction associated with ductal obstruction resulting in AIRWAY OBSTRUCTION; chronic RESPIRATORY INFECTIONS; PANCREATIC INSUFFICIENCY; maldigestion; salt depletion; and HEAT PROSTRATION.
Helium. A noble gas with the atomic symbol He, atomic number 2, and atomic weight 4.003. It is a colorless, odorless, tasteless gas that is not combustible and does not support combustion. It was first detected in the sun and is now obtained from natural gas. Medically it is used as a diluent for other gases, being especially useful with oxygen in the treatment of certain cases of respiratory obstruction, and as a vehicle for general anesthetics. (Dorland, 27th ed)
A chronic multi-system disorder of CONNECTIVE TISSUE. It is characterized by SCLEROSIS in the SKIN, the LUNGS, the HEART, the GASTROINTESTINAL TRACT, the KIDNEYS, and the MUSCULOSKELETAL SYSTEM. Other important features include diseased small BLOOD VESSELS and AUTOANTIBODIES. The disorder is named for its most prominent feature (hard skin), and classified into subsets by the extent of skin thickening: LIMITED SCLERODERMA and DIFFUSE SCLERODERMA.
Severe or complete loss of motor function in all four limbs which may result from BRAIN DISEASES; SPINAL CORD DISEASES; PERIPHERAL NERVOUS SYSTEM DISEASES; NEUROMUSCULAR DISEASES; or rarely MUSCULAR DISEASES. The locked-in syndrome is characterized by quadriplegia in combination with cranial muscle paralysis. Consciousness is spared and the only retained voluntary motor activity may be limited eye movements. This condition is usually caused by a lesion in the upper BRAIN STEM which injures the descending cortico-spinal and cortico-bulbar tracts.
The capability of the LUNGS to distend under pressure as measured by pulmonary volume change per unit pressure change. While not a complete description of the pressure-volume properties of the lung, it is nevertheless useful in practice as a measure of the comparative stiffness of the lung. (From Best & Taylor's Physiological Basis of Medical Practice, 12th ed, p562)
Severity of Illness Index
Tendency of the smooth muscle of the tracheobronchial tree to contract more intensely in response to a given stimulus than it does in the response seen in normal individuals. This condition is present in virtually all symptomatic patients with asthma. The most prominent manifestation of this smooth muscle contraction is a decrease in airway caliber that can be readily measured in the pulmonary function laboratory.
The science, art, or technology dealing with processes involved in the separation of metals from their ores, the technique of making or compounding the alloys, the techniques of working or heat-treating metals, and the mining of metals. It includes industrial metallurgy as well as metallurgical techniques employed in the preparation and working of metals used in dentistry, with special reference to orthodontic and prosthodontic appliances. (From Jablonski, Dictionary of Dentistry, 1992, p494)
Air Pollutants, Occupational
Carbon monoxide (CO). A poisonous colorless, odorless, tasteless gas. It combines with hemoglobin to form carboxyhemoglobin, which has no oxygen carrying capacity. The resultant oxygen deprivation causes headache, dizziness, decreased pulse and respiratory rates, unconsciousness, and death. (From Merck Index, 11th ed)
Sarcoidosis affecting predominantly the lungs, the site most frequently involved and most commonly causing morbidity and mortality in sarcoidosis. Pulmonary sarcoidosis is characterized by sharply circumscribed granulomas in the alveolar, bronchial, and vascular walls, composed of tightly packed cells derived from the mononuclear phagocyte system. The clinical symptoms when present are dyspnea upon exertion, nonproductive cough, and wheezing. (Cecil Textbook of Medicine, 19th ed, p431)
A class of statistical methods applicable to a large set of probability distributions used to test for correlation, location, independence, etc. In most nonparametric statistical tests, the original scores or observations are replaced by another variable containing less information. An important class of nonparametric tests employs the ordinal properties of the data. Another class of tests uses information about whether an observation is above or below some fixed value such as the median, and a third class is based on the frequency of the occurrence of runs in the data. (From McGraw-Hill Dictionary of Scientific and Technical Terms, 4th ed, p1284; Corsini, Concise Encyclopedia of Psychology, 1987, p764-5)
Procedures for finding the mathematical function which best describes the relationship between a dependent variable and one or more independent variables. In linear regression (see LINEAR MODELS) the relationship is constrained to be a straight line and LEAST-SQUARES ANALYSIS is used to determine the best fit. In logistic regression (see LOGISTIC MODELS) the dependent variable is qualitative rather than continuously variable and LIKELIHOOD FUNCTIONS are used to find the best relationship. In multiple regression, the dependent variable is considered to depend on more than a single independent variable.
Analysis of Variance
Nebulizers and Vaporizers
Tomography, X-Ray Computed
Studies in which subsets of a defined population are identified. These groups may or may not be exposed to factors hypothesized to influence the probability of the occurrence of a particular disease or other outcome. Cohorts are defined populations which, as a whole, are followed in an attempt to determine distinguishing subgroup characteristics.
Age as a constituent element or influence contributing to the production of a result. It may be applicable to the cause or the effect of a circumstance. It is used with human or animal concepts but should be differentiated from AGING, a physiological process, and TIME FACTORS which refers only to the passage of time.
Studies which start with the identification of persons with a disease of interest and a control (comparison, referent) group without the disease. The relationship of an attribute to the disease is examined by comparing diseased and non-diseased persons with regard to the frequency or levels of the attribute in each group.
Studies used to test etiologic hypotheses in which inferences about an exposure to putative causal factors are derived from data relating to characteristics of persons under study or to events or experiences in their past. The essential feature is that some of the persons under study have the disease or outcome of interest and their characteristics are compared with those of unaffected persons.
Reproducibility of Results
The statistical reproducibility of measurements (often in a clinical context), including the testing of instrumentation or techniques to obtain reproducible results. The concept includes reproducibility of physiological measurements, which may be used to develop rules to assess probability or prognosis, or response to a stimulus; reproducibility of occurrence of a condition; and reproducibility of experimental results.
Muscular Dystrophy, Duchenne
An X-linked recessive muscle disease caused by an inability to synthesize DYSTROPHIN, which is involved with maintaining the integrity of the sarcolemma. Muscle fibers undergo a process that features degeneration and regeneration. Clinical manifestations include proximal weakness in the first few years of life, pseudohypertrophy, cardiomyopathy (see MYOCARDIAL DISEASES), and an increased incidence of impaired mentation. Becker muscular dystrophy is a closely related condition featuring a later onset of disease (usually adolescence) and a slowly progressive course. (Adams et al., Principles of Neurology, 6th ed, p1415)
Predictive Value of Tests
In screening and diagnostic tests, the probability that a person with a positive test is a true positive (i.e., has the disease), is referred to as the predictive value of a positive test; whereas, the predictive value of a negative test is the probability that the person with a negative test does not have the disease. Predictive value is related to the sensitivity and specificity of the test.
A vague complaint of debility, fatigue, or exhaustion attributable to weakness of various muscles. The weakness can be characterized as subacute or chronic, often progressive, and is a manifestation of many muscle and neuromuscular diseases. (From Wyngaarden et al., Cecil Textbook of Medicine, 19th ed, p2251)
Condition in which no acceleration, whether due to gravity or any other force, can be detected by an observer within a system. It also means the absence of weight or the absence of the force of gravity acting on a body. Microgravity, gravitational force between 0 and 10 -6 g, is included here. (From NASA Thesaurus, 1988)
Diseases which have one or more of the following characteristics: they are permanent, leave residual disability, are caused by nonreversible pathological alteration, require special training of the patient for rehabilitation, or may be expected to require a long period of supervision, observation, or care. (Dictionary of Health Services Management, 2d ed)
Studies comparing two or more treatments or interventions in which the subjects or patients, upon completion of the course of one treatment, are switched to another. In the case of two treatments, A and B, half the subjects are randomly allocated to receive these in the order A, B and half to receive them in the order B, A. A criticism of this design is that effects of the first treatment may carry over into the period when the second is given. (Last, A Dictionary of Epidemiology, 2d ed)
Respiratory Dead Space
Any method of artificial breathing that employs mechanical or non-mechanical means to force the air into and out of the lungs. Artificial respiration or ventilation is used in individuals who have stopped breathing or have RESPIRATORY INSUFFICIENCY to increase their intake of oxygen (O2) and excretion of carbon dioxide (CO2).
The unstable triatomic form of oxygen, O3. It is a powerful oxidant that is produced for various chemical and industrial uses. Its production is also catalyzed in the ATMOSPHERE by ULTRAVIOLET RAY irradiation of oxygen or other ozone precursors such as VOLATILE ORGANIC COMPOUNDS and NITROGEN OXIDES. About 90% of the ozone in the atmosphere exists in the stratosphere (STRATOSPHERIC OZONE).
Measurable and quantifiable biological parameters (e.g., specific enzyme concentration, specific hormone concentration, specific gene phenotype distribution in a population, presence of biological substances) which serve as indices for health- and physiology-related assessments, such as disease risk, psychiatric disorders, environmental exposure and its effects, disease diagnosis, metabolic processes, substance abuse, pregnancy, cell line development, epidemiologic studies, etc.
Agricultural Workers' Diseases
Diseases in persons engaged in cultivating and tilling soil, growing plants, harvesting crops, raising livestock, or otherwise engaged in husbandry and farming. The diseases are not restricted to farmers in the sense of those who perform conventional farm chores: the heading applies also to those engaged in the individual activities named above, as in those only gathering harvest or in those only dusting crops.
Maleness or femaleness as a constituent element or influence contributing to the production of a result. It may be applicable to the cause or effect of a circumstance. It is used with human or animal concepts but should be differentiated from SEX CHARACTERISTICS, anatomical or physiological manifestations of sex, and from SEX DISTRIBUTION, the number of males and females in given circumstances.
Quality of Life
Spinal Cord Injuries
Amyotrophic Lateral Sclerosis
A degenerative disorder affecting upper MOTOR NEURONS in the brain and lower motor neurons in the brain stem and SPINAL CORD. Disease onset is usually after the age of 50 and the process is usually fatal within 3 to 6 years. Clinical manifestations include progressive weakness, atrophy, FASCICULATION, hyperreflexia, DYSARTHRIA, dysphagia, and eventual paralysis of respiratory function. Pathologic features include the replacement of motor neurons with fibrous ASTROCYTES and atrophy of anterior SPINAL NERVE ROOTS and corticospinal tracts. (From Adams et al., Principles of Neurology, 6th ed, pp1089-94)
The determination of oxygen-hemoglobin saturation of blood either by withdrawing a sample and passing it through a classical photoelectric oximeter or by electrodes attached to some translucent part of the body like finger, earlobe, or skin fold. It includes non-invasive oxygen monitoring by pulse oximetry.
Arterial blood gas tensions during upper gastrointestinal endoscopy. (1/2375)Arterial blood gas tensions were measured before and during upper gastrointestinal endoscopy, with (group I) and without (group 2) sedation with intravenous diazepam. There was a highly significant fall in the PaO2, which occurred in both groups and was therefore not attributable to diazepam. Measurement of FEV, and FVC before endoscopy had no predictive value for those patients whose PaO2 fell the most. (+info)
Comparative total mortality in 25 years in Italian and Greek middle aged rural men. (2/2375)STUDY OBJECTIVE: Mortality over 25 years has been low in the Italian and very low in the Greek cohorts of the Seven Countries Study; factors responsible for this particularity were studied in detail. PARTICIPANTS AND SETTINGS: 1712 Italian and 1215 Greek men, aged 40-59 years, cohorts of the Seven Countries Study, representing over 95% of the populations in designated rural areas. DESIGN: Entry (1960-61) data included age, systolic blood pressure (SBP), smoking habits, total serum cholesterol, body mass index (BMI), arm circumference, vital capacity (VC), and forced expiratory volume in 3/4 seconds (FEV); the same data were obtained 10 years later. Multivariate Cox analysis was performed with all causes death in 25 years as end point. MAIN RESULTS: Italian men had higher entry levels of SBP, arm circumference, BMI, and VC; Greek men had higher cholesterol levels, smoking habits, and FEV. Mortality of Italian men was higher throughout; at 25 years cumulative mortality was 48.3% and 35.3% respectively. Coronary heart disease and stroke mortality increased fivefold in Italy and 10-fold in Greece between years 10 and 25. The only risk factor with a significantly higher contribution to mortality in Italian men was cholesterol. However, differences in entry SBP (higher in Italy) and FEV (higher in Greece) accounted for, according to the Lee method, 75% of the differential mortality between the two populations. At 10 years increases in SBP, cholesterol, BMI, and decreases in smoking habits, VC, FEV, and arm circumference had occurred (deltas). SBP increased more and FEV and VC decreased more in Italy than in Greece. Deltas, fed stepwise in the original model for the prediction of 10 to 25 years mortality, were significant for SBP, smoking, arm circumference, and VC in Greece, and for SBP and VC in Italy. CONCLUSION: Higher mortality in Italian men is related to stronger positive effects of entry SBP and weaker negative (protective) effects of FEV; in addition 10 year increases in SBP are higher and 10 year decreases in FEV are larger in Italy. Unaccounted factors, however, related to, for example, differences in the diet, may also have contributed to the differential mortality of these two Mediterranean populations. (+info)
Double-blind intervention trial on modulation of ozone effects on pulmonary function by antioxidant supplements. (3/2375)The aim of this study was to investigate whether the acute effects of ozone on lung function could be modulated by antioxidant vitamin supplementation in a placebo-controlled study. Lung function was measured in Dutch bicyclists (n = 38) before and after each training session on a number of occasions (n = 380) during the summer of 1996. The vitamin group (n = 20) received 100 mg of vitamin E and 500 mg of vitamin C daily for 15 weeks. The average ozone concentration during exercise was 77 microg/m3 (range, 14-186 microg/m3). After exclusion of subjects with insufficient compliance from the analysis, a difference in ozone exposure of 100 microg/m3 decreased forced expiratory volume in 1 second (FEV1) 95 ml (95% confidence interval (CI) -265 to -53) in the placebo group and 1 ml (95% CI -94 to 132) in the vitamin group; for forced vital capacity, the change was -125 ml (95% CI -384 to -36) in the placebo group and -42 ml (95% CI -130 to 35) in the vitamin group. The differences in ozone effect on lung function between the groups were statistically significant. The results suggest that supplementation with the antioxidant vitamins C and E confers partial protection against the acute effects of ozone on FEV1 and forced vital capacity in cyclists. (+info)
Exhaled and nasal NO levels in allergic rhinitis: relation to sensitization, pollen season and bronchial hyperresponsiveness. (4/2375)Exhaled nitric oxide is a potential marker of lower airway inflammation. Allergic rhinitis is associated with asthma and bronchial hyperresponsiveness. To determine whether or not nasal and exhaled NO concentrations are increased in allergic rhinitis and to assess the relation between hyperresponsiveness and exhaled NO, 46 rhinitic and 12 control subjects, all nonasthmatic nonsmokers without upper respiratory tract infection, were randomly selected from a large-scale epidemiological survey in Central Norway. All were investigated with flow-volume spirometry, methacholine provocation test, allergy testing and measurement of nasal and exhaled NO concentration in the nonpollen season. Eighteen rhinitic subjects completed an identical follow-up investigation during the following pollen season. Exhaled NO was significantly elevated in allergic rhinitis in the nonpollen season, especially in perennially sensitized subjects, as compared with controls (p=0.01), and increased further in the pollen season (p=0.04), mainly due to a two-fold increase in those with seasonal sensitization. Nasal NO was not significantly different from controls in the nonpollen season and did not increase significantly in the pollen season. Exhaled NO was increased in hyperresponsive subjects, and decreased significantly after methacholine-induced bronchoconstriction, suggesting that NO production occurs in the peripheral airways. In allergic rhinitis, an increase in exhaled nitric oxide on allergen exposure, particularly in hyperresponsive subjects, may be suggestive of airway inflammation and an increased risk for developing asthma.

Orally exhaled nitric oxide levels are related to the degree of blood eosinophilia in atopic children with mild-intermittent asthma. (5/2375)Increased levels of nitric oxide have been found in expired air of patients with asthma, and these are thought to be related to the airway inflammatory events that characterize this disorder. Since, in adults, bronchial inflammatory changes are present even in mild disease, the present study was designed to evaluate whether a significant proportion of children with mild-intermittent asthma could have increased exhaled air NO concentrations. Twenty-two atopic children (aged 11.1+/-0.8 yrs) with mild-intermittent asthma, treated only with inhaled beta2-adrenoreceptor agonists on demand and 22 age-matched controls were studied. NO concentrations in orally exhaled air, measured by chemiluminescence, were significantly higher in asthmatics, as compared to controls (19.4+/-3.3 parts per billion (ppb) and 4.0+/-0.5 ppb, respectively; p<0.01). Interestingly, 14 out of 22 asthmatic children had NO levels >8.8 ppb (i.e. >2 standard deviations of the mean in controls). In asthmatic patients, but not in control subjects, statistically significant correlations were found between exhaled NO levels and absolute number or percentage of blood eosinophils (r=0.63 and 0.56, respectively; p<0.01, each comparison). In contrast, exhaled NO levels were not correlated with forced expiratory volume in one second (FEV1) or forced expiratory flows at 25-75% of vital capacity (FEF25-75%) or forced vital capacity (FVC), either in control subjects, or in asthmatic patients (p>0.1, each correlation). These results suggest that a significant proportion of children with mild-intermittent asthma may have airway inflammation, as shown by the presence of elevated levels of nitric oxide in the exhaled air. The clinical relevance of this observation remains to be established. (+info)
Risk factors for lower airway bacterial colonization in chronic bronchitis. (6/2375)The aim of this study was to determine the prevalence and risk factors for lower airway bacterial colonization (LABC) in stable chronic bronchitis (CB). Forty-one outpatients with CB were enrolled in the study (age 63.8+/-9.1 yrs (mean+/-SD); forced expiratory volume in one second (FEV1)/forced vital capacity (FVC) 62.8+/-11.2; current/former smokers 24/17). All patients had normal chest radiographs and an indication for performing fibreoptic bronchoscopy (pulmonary nodule, remote haemoptysis). The protected specimen brush (PSB) was used for bacterial sampling, and concentrations > or = 1,000 colony-forming units (cfu) x mL(-1) were considered positive for LABC. The repeatability of the procedure in CB was assessed in a random subsample of 18 subjects. A 72.2% quantitative agreement was found in the repeatability assessment of the PSB technique. Positive PSB cultures, obtained in 9 out of 41 (22%) patients, mainly yielded Haemophilus influenzae. The logistic regression model, used to determine which variables were related to colonization, showed that LABC was associated with current smoking (odds ratio (OR) 9.83, confidence interval (CI) 1.16-83.20) and low FVC (OR 0.73, CI 0.65-0.81). Age and FEV1 were not related to LABC. It was concluded that the prevalence of LABC in stable CB is high (22%), and current smoking is an important risk factor. (+info)
Predisposing factors to bacterial colonization in chronic obstructive pulmonary disease. (7/2375)The aim of this prospective observational study was to determine those factors influencing bacterial colonization in patients with stable chronic obstructive pulmonary disease (COPD). Eighty-eight outpatients with stable COPD and 20 patients with normal spirometry and chest radiography (controls) had a fibreoptic bronchoscopy performed with topical aerosol anaesthesia. Bacterial colonization was determined using the protected specimen brush (PSB) with a cut-off > or = 10(3) colony-forming units (CFU x mL(-1)). The influence of age, degree of airflow obstruction, smoking habit, pack-yrs of smoking, and chest radiographic findings on bacterial colonization were assessed by univariate and multivariate analysis. Significant bacterial growth was found in 40% of patients and in none of the controls. Haemophilus influenzae, Streptococcus viridans, S. pneumoniae and Moraxella catarrhalis were the most frequent pathogens. After adjustment for other variables, severe airflow limitation (odds ratio (OR) 5.11, 95% confidence interval (CI) 1.45-17.9) and current smoking (OR 3.17, 95% CI 2.5-8) remained associated with positive bacterial cultures. When only potentially pathogenic micro-organisms were considered, significant bacterial growth was found in 30.7% of patients, with severe airflow obstruction (OR 9.28, 95% CI 2.19-39.3) being the only variable independently associated with positive bacterial cultures. Our results show that stable chronic obstructive pulmonary disease patients have a high prevalence of bacterial colonization of distal airways which is mainly related to the degree of airflow obstruction and cigarette smoking.

A pilot study of low-dose erythromycin in bronchiectasis. (8/2375)Patients with bronchiectasis suffer from sputum production, recurrent exacerbations, and progressive airway destruction. Erythromycin is effective in diffuse panbronchiolitis, another suppurative airway disorder, although its efficacy is unknown in idiopathic bronchiectasis. A double-blind placebo-controlled study was therefore conducted to evaluate the effects of 8-week administration of low dose erythromycin (500 mg b.i.d.) in steady-state idiopathic bronchiectasis. Patients in the erythromycin group (n=11, 8 female, mean age 50+/-15 yrs), but not the placebo group (n=10, 8 female, mean age 59+/-16 yrs) had significantly improved forced expiratory volume in one second, forced vital capacity and 24-h sputum volume after 8 weeks (p<0.05). There was no parallel improvement in sputum pathogens, leukocytes, interleukin (IL)-1alpha and IL-8, tumour necrosis factor-alpha, or leukotriene B4. The results of this pilot study show that low-dose erythromycin improves lung function and sputum volume in bronchiectasis. Further studies are indicated to evaluate the efficacy of long-term erythromycin therapy in bronchiectasis. (+info)

A simple method to detect expiratory flow limitation during spontaneous breathing | European Respiratory Society
Patients with severe chronic obstructive pulmonary disease (COPD) often exhale along the same flow-volume curve during quiet breathing as during a forced expiratory vital capacity manoeuvre, and this has been taken as indicating flow limitation at rest. To obtain such curves, a body plethysmograph and the patients co-operation are required. We propose a simple technique which does not entail these requirements. It consists in applying negative pressure at the mouth during a tidal expiration (NEP). Patients in whom NEP elicits an increase in flow throughout the expiration are not flow-limited. In contrast, patients in whom application of NEP does not elicit an increase in flow during most or part of the tidal expiration are considered as flow-limited. Using this technique, 26 stable COPD patients were studied sitting and supine. Eleven patients were flow-limited both seated and supine, eight were flow-limited only when supine, and seven were not flow-limited either seated or supine. Only 5 of 19 ...

Dysanapsis in normal lungs assessed by the relationship between maximal flow, static recoil, and vital capacity
To quantify the degree of association, if any, between lung size and airway size in humans, the ratio of a measurement known to be sensitive to airway size (maximal expiratory flow divided by static recoil pressure at 50% of vital capacity) to one sensitive to lung size (vital capacity) was examined …
A reduced FEV1 is as a marker of airflow obstruction where TLC is normal or increased, whilst both TLC and FEV1 are reduced in a restrictive ventilatory defect. Aim: To determine the usefulness of the FEV1/TLC ratio in determining the presence of an obstructive or restrictive ventilatory defect. Methods: Lung function measurements of FEV1, VC and TLC were reviewed and divided into four principle groups - 1) normal (both FEV1 and TLC , -1.64 SR), 2) airways obstruction (FEV1%VC , -1.64SR, TLC normal or , +1.65SR), 3) restrictive defect (TLC , -1.65 SR) and 4) a mixed obstructive-restrictive defect. Results: The group (n = 806; age 20 - 97 yrs) and sub-group analysis is shown in the table. ...

N2 - Study objective: The ratio between forced expiratory flow between 25% and 75% of vital capacity (FEF25-75) and FVC is thought to reflect dysanapsis between airway size and lung size. A low FEF25-75/FVC ratio is associated with airway responsiveness to methacholine in middle-aged and older men. The current study was designed to assess this relationship in both male and female subjects over a broader range of ages. Study design: Data analysis of consecutive subjects who had a ≥ 20% reduction in FEV1 after ≤ 189 cumulative units of methacholine over a 7-year period. Setting: Pulmonary function laboratory in a university-affiliated hospital. Patients: A total of 764 consecutive subjects aged 4 to 91 years (mean ± SD ...

Vital Capacity - Melody Schaper
Vital Capacity. *This is not a science lesson*. Vital capacity refers to the amount of oxygen we can bring into our lungs in one breath and release. The more the better. Oxygen brings nutrients to every part of our being. Carbon dioxide is released when we exhale, which is toxic to us. The deeper the exhalation the more cleansed we become. Oxygen gives us life and vitality. Releasing carbon dioxide cleanses us from what is harmful.. I thought that was interesting as a scientific reality for many years. Lately I have been living in the metaphor of this. Vital capacity is our potential for true vitality. Its about living fully consciously reaching for and receiving what we need and letting go of what we dont need anymore. We cleanse our selves with every single breath.. Our breath cycle, the constant and repetitive action of breathing in and out is a natural process that heals and strengthens us in every moment. Filling up, gathering from and opening to what is all around us provides ...

PY - 2019/4/8. Y1 - 2019/4/8. N2 - BACKGROUND: Pulmonary function impairments are more common among people living with HIV (PLWH), as are contributing risk behaviors. To understand the effects of human immunodeficiency virus (HIV) infection independent of risk behaviors, pulmonary function was evaluated in lifestyle-comparable HIV-infected and -uninfected AGEhIV cohort participants. METHODS: Prevalence of obstructive lung disease in 544 HIV-infected and 529 HIV-uninfected participants was determined using spirometry. Logistic regression was used to assess HIV as a determinant of obstructive lung disease. Additional ...
The measurements were performed in two piglets (g08 and g10) during baseline conditions in healthy lung (g08-c003.get, g10-c003.get), after induction of acute lung injury by repeated bronchoalveolar lavage (g08-c017.get, g10-c019.get) and after administration of surfactant (g08-c035.get, g10-c029.get) during pressure-controlled ventilation. The EIT raw data were acquired during an incremental and decremental PEEP trial (stepwise increase and decrease of positive end-expiratory pressure from 0 cm H2O to 25 cm H2O and back) at a rate of 13 frames/s. Each measurement lasted 180 s. The excitation current was 70 kHz. Data were published in Dargaville, P.A., Rimensberger, P.M., Frerichs, I.

Longitudinal effects of change in body mass on measurements of ventilatory capacity. | Thorax
BACKGROUND: In several longitudinal studies changes in body mass and in forced expiratory volume in one second (FEV1) have been found to be negatively correlated. This paper tests the hypothesis that failure to allow for the association can lead to error in the interpretation of longitudinal measurements of ventilatory capacity. METHODS: Male shipyard workers (n = 1005) were assessed on two occasions with an average interval between measurements of 6.9 years. A respiratory symptoms questionnaire, detailed anthropometric measurements, and dynamic spirometric tests were undertaken. Multiple regression analysis was used to identify variables which contributed to the changes in lung function. RESULTS: After allowing for age and growth in stature, a change in body mass of 1 kg was, on average, associated with a mean (SE) converse change in FEV1 of 17.6 (2.0) ml, and in forced vital capacity (FVC) of 21.1 (2.5) ml. Neglect of changes in body mass (which in this context reflected changes in body fat) ...

Methods: Thirty consecutive morbidly obese patients undergoing gastric banding were investigated. All subjects were studied the day before surgery (T0) and on postoperative day one (T1). Forced Vital Capacity (FVC) was measured, together with heart rate, mean arterial pressure and respiratory rate. At T0 measurements were taken in a random fashion with subjects in upright and in supine position. Subjects were then investigated after surgery in the supine position (T1). Postoperative pain was assessed at T1 using visual analogue scale. Intraoperative variables were also collected ...
Early life origins of chronic obstructive pulmonary disease | Thorax
This analysis of a large multicentre population indicates that adult lung function and susceptibility to COPD is partly determined early in life, and that the impact of childhood disadvantage appears to persist. Maternal asthma, paternal asthma, childhood asthma, severe respiratory infections before the age of 5 years and maternal smoking were associated with a lower adult FEV1 level, and having any one or more of these factors constituted a considerable disadvantage with regard to adult lung function and COPD. Subjects with an increasing number of childhood disadvantage factors had an increasingly lower level of FEV1 in adult life, a slightly larger decline in FEV1 and the prevalence of COPD was substantially increased. The impairment of FEV1 persisted up to the maximum age in our study population (56 years) and no catch-up was detected. Childhood disadvantage was as common in the population as current smoking, and showed an equally large impact on lung function and COPD and a slightly smaller ...
Spirometry - Dr Vivek Kumar
Computerised Spirometry measures the forced vital capacity, forced expiratory volume in one second, and many more lung parameters including your lung age. It helps us in differentiating between obstructive and restrictive pattern of your disease. Different types of obstructive airway diseases like asthma copd can be easily picked by this investigation. A very useful tool used in our clinic for diagnosing as well as monitoring the progress and prognosis.. What is spirometry?. Spirometry is a test used for lung conditions, such as COPD* or asthma. It is a simple breathing test that measures the amount of air a person can blow out of the lungs (volume). It also measures how fast he or she can blow it out (flow). It is one of the best and most common lung function tests. Spirometry is often done in your healthcare providers office or in a clinic. Spirometry can detect COPD before symptoms become severe. Based on this test, your provider can tell if you have COPD and, if so, how severe it is.. What ...
Residency opening - 1 Sept 2020 - VITAL CAPACITIES
Were very excited to welcome you to Vital Capacities! Over the past 3 months weve been working with the four resident artists - Seecum Cheung, Joey Holder, Daniel Locke and Romily Alice Walden, plus access specialist, Sarah Pickthall and web designer, Oli Pyle to create this new, accessible space for artists and audiences. Vital Capacities was partly inspired by the Covid-19 pandemic and travel restrictions, but we mainly took inspiration from seeing the limitations travel (and away from home accommodation) put on traditional residencies. These limits often affect disabled people, people with families, those with less resources, and people who dont want to or cant travel / stay away from home for other reasons. So, we thought wed try and create a virtual space that could offer similar value without the restrictions. We wanted to develop a site that could provide some of the opportunities a residency can give: space and time to think; exploring and developing ideas; making new connections; ...

This vital capacity calculator determines the vital capacity in litres based on tidal volume, inspiratory and expiratory reserve volumes.
Data from the Tucson epidemiological study of airways obstructive disease on smoking of non-tobacco cigarettes such as marijuana were analysed to determine the effect of such smoking on respiratory symptoms and pulmonary function. Among adults aged under 40, 14% had smoked non-tobacco cigarettes at some time and 9% were current users. The prevalence of respiratory symptoms was increased in smokers of non-tobacco cigarettes. After tobacco smoking had been controlled for men who smoked non-tobacco cigarettes showed significant decreases in expiratory flow rates at low lung volumes and in the ratio of the forced expiratory volume in one second to the vital capacity. This effect on pulmonary function in male non-tobacco cigarette smokers was greater than the effect of tobacco cigarette smoking. These data suggest that non-tobacco cigarette smoking may be an important risk factor in young adults with respiratory symptoms or evidence of airways obstruction. ...

The GLI-2012 equations are the most robust spirometry reference equations to date. The main advantage of these equations is that there is a smooth transition across the ages (i.e. no changes from paediatric to adult equations) and a well-defined lower limit of normal (LLN) for all ages. The group demonstrated that the scatter around predicted values is not constant, but varies with age, such that fixed thresholds for abnormality (e.g. 80% predicted for FEV1 or 0.70 for the FEV1/forced vital capacity (FVC) ratio) across all ages are inappropriate and can lead to significant misclassification. Using z-scores, which indicate how many standard deviations a measurement is from its predicted value, overcomes the bias due to age, height, sex and ethnicity, and is useful for defining the LLN. The American Thoracic Society (ATS) and the ERS both recommend the use of the fifth centile (i.e. −1.64 z-scores) to define the LLN .. The GLI group also found that, by combining such a large number of ...

The role that vitamin D plays in pulmonary function remains uncertain. Epidemiological studies reported mixed findings for serum 25-hydroxyvitamin D (25(OH)D)-pulmonary function association. We conducted the largest cross-sectional meta-analysis of the 25(OH)D-pulmonary function association to date, based on nine European ancestry (EA) cohorts (n 22 838) and five African ancestry (AA) cohorts (n 4290) in the Cohorts for Heart and Aging Research in Genomic Epidemiology Consortium. Data were analysed using linear models by cohort and ancestry. Effect modification by smoking status (current/former/never) was tested. Results were combined using fixed-effects meta-analysis. Mean serum 25(OH)D was 68 (sd 29) nmol/l for EA and 49 (sd 21) nmol/l for AA. For each 1 nmol/l higher 25(OH)D, forced expiratory volume in the 1st second (FEV1) was higher by 1·1 ml in EA (95 % CI 0·9, 1·3; P,0·0001) and 1·8 ml (95 % CI 1·1, 2·5; P,0·0001) in AA (Prace difference=0·06), and forced vital capacity (FVC) ...

Something Noticeably Absent at the ALS Clinic | Neva Story
May 1, 2014, by Todd Neva. There was something noticeably absent at the ALS clinic: Kristin crying.. The main reason for that was the news of my breathing. I scored 92% on forced vital capacity. FVC is a measurement of how much air I can expel from my lungs. As my diaphragm weakens, I lose the ability to expel carbon dioxide. Breathing is critical for obvious reasons, but this measurement is important because it determines when intervention is required. Surgery for a feeding tube, for example, requires that my breathing is at least 50%.. At my first ALS clinic, my breathing was 104%. Six months ago it was 90%. Kristin was bracing for 87%, but when I blew a 92%, Kristin smiled.. Before the clinic, last Tuesday, April 22, we had an opportunity to speak at an ALS support group. There were three other couples in attendance. It was difficult to know what to say to them. Weve spoken to other groups, but the folks at the support group are in the ALS trenches with us, and in some ways have suffered ...
