A new model rat with acute bronchiolitis and its application to research on the toxicology of inhaled particulate matter. (1/4931)

The aim of the present study was to establish a useful animal model that simulates humans sensitive to inhaled particulate matter (PM). We have developed a new rat model of acute bronchiolitis (Br) by exposing animals to NiCl2 (Ni) aerosols for five days. Three days following the Ni exposure, the animals developed signs of tachypnea, mucous hypersecretion, and bronchiolar inflammation which seemed to progress quickly during the fourth to fifth day. They recovered from lesions after four weeks in clean air. To assess the sensitivity of the Br rats to inhaled particles, two kinds of PM of respirable size were tested with doses similar to or a little higher to the recommended threshold limit values (TLVs) for the working environment in Japan. Titanium dioxide (TiO2 = Ti) was chosen as an inert and insoluble particles and vanadium pentoxide (V2O5 = V), as a representative soluble and toxic airborne material. The Br rats exposed to either Ti or V were compared the pathological changes in the lungs and the clearance of particles to those in normal control or Br rats kept in clean air. The following significant differences were observed in Br rats: 1. delayed recovery from pre-existing lesions or exacerbated inflammation, 2. reductions in deposition and clearance rate of inhaled particles with the progress of lesions. The present results suggest that Br rats are more susceptible to inhaled particles than control rats. Therefore, concentrations of particulate matter lower than the TLVs for Japan, which have no harmful effects on normal lungs, may not always be safe in the case of pre-existing lung inflammation.  (+info)

Cytokines and inflammatory mediators do not indicate acute infection in cystic fibrosis. (2/4931)

Various treatment regimens and difficulties with research design are encountered with cystic fibrosis (CF) because no standard diagnostic criteria exist for defining acute respiratory exacerbations. This study evaluated the role of serial monitoring of concentrations of selected cytokines and inflammatory mediators in serum and sputum as predictors of respiratory exacerbation, as useful outcome measures for CF, and to guide therapy. Interleukin-8 (IL-8), tumor necrosis factor alpha (TNF-alpha), neutrophil elastase-alpha-1-protease inhibitor complex (NE complex), protein, and alpha-1-protease inhibitor (alpha-1-PI) were measured in serum and sputum collected from CF patients during respiratory exacerbations and periods of well-being. Levels of NE complex, protein, and alpha-1-PI in sputum rose during respiratory exacerbations and fell after institution of antibiotic therapy (P = 0.078, 0.001, and 0.002, respectively). Mean (+/- standard error of the mean) levels of IL-8 and TNF-alpha were extremely high in sputum (13,780 +/- 916 and 249.4 +/- 23.5 ng/liter, respectively) but did not change significantly with clinical deterioration of the patient (P > 0.23). IL-8 and TNF-alpha were generally undetectable in serum, and therefore these measures were unhelpful. Drop in forced expiratory volume in 1 s was the only clinical or laboratory parameter that was close to being a determinant of respiratory exacerbation (P = 0.055). This study provides evidence of intense immunological activity occurring continually within the lungs of adult CF patients. Measurement of cytokines and inflammatory mediators in CF sputum is not helpful for identifying acute respiratory exacerbations.  (+info)

Effects of acute prolonged exposure to high-altitude hypoxia on exercise-induced breathlessness. (3/4931)

The direct effects of hypoxia on exercise-induced breathlessness are unclear. Increased breathlessness on exercise is known to occur at high altitude, but it is not known whether this is related to the hypoxia per se, or to other ventilatory parameters. To examine the role of high-altitude hypoxia in exercise-induced breathlessness, studies were performed in 10 healthy, normal subjects at sea level and after acute exposure to an altitude of 4450 m. Although the perception of hand weights did not alter between sea level and high altitude, the intensity of exercise-induced breathlessness increased significantly at high altitude. This was associated with a higher minute ventilation and respiratory frequency for any given exercise level, whereas tidal volume was not significantly altered from sea level values. The increased intensity of breathlessness with exercise did not change significantly over the 5 days at high altitude. These results suggest that the increased intensity of exercise-induced breathlessness at high altitude is not related to peripheral mechanisms or the pattern of ventilation, or to the level of hypoxia per se, but to the level of reflexly increased ventilation.  (+info)

Effect of thoracotomy and lung resection on exercise capacity in patients with lung cancer. (4/4931)

BACKGROUND: Resection is the treatment of choice for lung cancer, but may cause impaired cardiopulmonary function with an adverse effect on quality of life. Few studies have considered the effects of thoracotomy alone on lung function, and whether the operation itself can impair subsequent exercise capacity. METHODS: Patients being considered for lung resection (n = 106) underwent full static and dynamic pulmonary function testing which was repeated 3-6 months after surgery (n = 53). RESULTS: Thoracotomy alone (n = 13) produced a reduction in forced expiratory volume in one second (FEV1; mean (SE) 2.10 (0.16) versus 1.87 (0.15) l; p<0.05). Wedge resection (n = 13) produced a non-significant reduction in total lung capacity (TLC) only. Lobectomy (n = 14) reduced forced vital capacity (FVC), TLC, and carbon monoxide transfer factor but exercise capacity was unchanged. Only pneumonectomy (n = 13) reduced exercise capacity by 28% (PVO2 23.9 (1.5) versus 17.2 (1.7) ml/min/kg; difference (95% CI) 6.72 (3.15 to 10.28); p<0.01) and three patients changed from a cardiac limitation to exercise before pneumonectomy to pulmonary limitation afterwards. CONCLUSIONS: Neither thoracotomy alone nor limited lung resection has a significant effect on exercise capacity. Only pneumonectomy is associated with impaired exercise performance, and then perhaps not as much as might be expected.  (+info)

Pseudo-steroid resistant asthma. (5/4931)

BACKGROUND: Steroid resistant asthma (SRA) represents a small subgroup of those patients who have asthma and who are difficult to manage. Two patients with apparent SRA are described, and 12 additional cases who were admitted to the same hospital are reviewed. METHODS: The subjects were selected from a tertiary hospital setting by review of all asthma patients admitted over a two year period. Subjects were defined as those who failed to respond to high doses of bronchodilators and oral glucocorticosteroids, as judged by subjective assessment, audible wheeze on examination, and serial peak flow measurements. RESULTS: In 11 of the 14 patients identified there was little to substantiate the diagnosis of severe or steroid resistant asthma apart from symptoms and upper respiratory wheeze. Useful tests to differentiate this group of patients from those with severe asthma appear to be: the inability to perform reproducible forced expiratory manoeuvres, normal airway resistance, and a concentration of histamine causing a 20% fall in the forced expiratory volume (FEV1) being within the range for normal subjects (PC20). Of the 14 subjects, four were health care staff and two reported childhood sexual abuse. CONCLUSION: Such patients are important to identify as they require supportive treatment which should not consist of high doses of glucocorticosteroids and beta2 adrenergic agonists. Diagnoses other than asthma, such as gastro-oesophageal reflux, hyperventilation, vocal cord dysfunction and sleep apnoea, should be sought as these may be a cause of glucocorticosteroid treatment failure and pseudo-SRA, and may respond to alternative treatment.  (+info)

Influence of family factors on the incidence of lower respiratory illness during the first year of life. (6/4931)

In a study of a cohort of over 2000 children born between 1963 and 1965, the incidence of bronchitis and pneumonia during their first year of life was found to be associated with several family factors. The most important determinant of respiratory illness in these infants was an attack of bronchitis or pneumonia in a sibling. The age of these siblings, and their number, also contributed to this incidence. Parental respiratory symptoms, including persistent cough and phlegm, and asthma or wheezing, as well as parental smoking habits, had lesser but nevertheless important effects. Parental smoking, however, stands out from all other factors as the one most amenable to change in seeking to prevent bronchitis and pneumonia in infants.  (+info)

Urinary cotinine and exposure to parental smoking in a population of children with asthma. (7/4931)

BACKGROUND: Studies of the effects of tobacco smoke often rely on reported exposure to cigarette smoke, a measure that is subject to bias. We describe here the relationship between parental smoking exposure as assessed by urinary cotinine excretion and lung function in children with asthma. METHODS: We studied 90 children 4-14 years of age, who reported a confirmed diagnosis or symptoms of asthma. In each child, we assessed baseline pulmonary function (spirometry) and bronchial responsiveness to carbachol stimulation. Urinary cotinine was measured by HPLC with ultraviolet detection. RESULTS: Urinary cotinine concentrations in the children were significantly correlated (P <0.001) with the number of cigarettes the parents, especially the mothers, smoked. Bronchial responsiveness to carbachol (but not spirometry test results) was correlated (P <0.03) with urinary cotinine in the children. CONCLUSION: Passive smoke exposure increases the bronchial responsiveness to carbachol in asthmatic children.  (+info)

Fragile lung in the Marfan syndrome. (8/4931)

Two cases of the Marfan syndrome presented with spontaneous pneumothorax. Both had chest radiographs showing bilateral bullae in the upper lung zones and pulmonary function tests consistent with mild emphysema. There were dereases in forced expiratory flow rates at low lung volumes, carbon monoxide transfer factor, and lung elastic recoil. It is suggested that pneumothorax and bullous emphysema in this syndrome are caused by a weakness in the pulmonary connective tissue framework.  (+info)

Bronchial reactivity to cigarette smoke (CBR) in a cross-section of 98 smokers has been investigated. All participants were subjects to skin-prick tests to common allergens, lung function measurements and bronchial challenges with methacholine and cigarette smoke. In 38 participants a rechallenge with cigarettes was performed 1 h after the first cigarette challenge. Lung function indices analysed were: forced expiratory volume in one second (FEV1); maximal expiratory flow at 75% of the forced vital capacity (MEF75%); and forced mid-expiratory flow between 25 and 75% of the forced vital capacity (FEF(25-75%)). All participants were tested for asthma and allergy, and were required to provide information regarding respiratory symptoms, first degree relatives with asthma and allergy and smoking habits. A substantial decrease was seen in all lung function indices after 12 cigarette-smoke inhalations, but only FEV1 was related to other variables. The maximal mean percentage fall in FEV1 was 10%, which ...

In this analysis of a large, prospective, population based cohort, lung function impairment was associated with an increased risk of having or developing CVD in adults; the highest risks were observed among those with GOLD 2 (moderate) and GOLD 3 or 4 (severe/very severe) COPD. After adjusting for multiple covariates, including age, sex, race, smoking status, diabetes, hypertension, cholesterol levels and fibrinogen levels, the relation between lung function impairment and CVD was reduced, suggesting that some of this relation may be mediated through these other factors.. Previous research suggests that systemic inflammation present in COPD leads to the increased CVD risk, and that treatment aimed at decreasing inflammation in those with COPD may decrease the development of cardiovascular disease or reduce event recurrence. Vascular inflammation may also contribute to impaired airway vascular smooth muscle relaxation in COPD. Treatment with agents that affect systemic inflammation or vascular ...

Pulmonary function tests (PFTs) help diagnose lung diseases like COPD. The most common PFTs include spirometry, diffusion tests, and plethysmography.
The AMA Guides to the Evaluation of Permanent Impairment ( AMA Guides ), Fifth Edition, changes the definition of normal (ie, the process of differentiating between an individual whose lung function is normal as opposed to an individual with Class 2 respiratory impairment) because the definition has changed over time. For example, the AMA Guides, First Edition (1971), used from the VA-Army 1961 Cooperative Study to construct tables of normal or predicted values during spirometry. Regression equations were used to calculate the predicted forced vital capacity, forced expiratory volume in the first second, and mandatory minute ventilation for men and women, by age and height. The Second Edition (1984) used data from a pulmonary function study in 251 healthy white individuals who lived 1400 meters above sea level (Utah), more than 90% of whom were members of the Mormon church (a very narrow segment of the American population). The AMA Guides, Third and Fourth Editions, continued to rely on ...
Lung function tests (also called pulmonary function tests, or PFTs) measure how well your lungs work. Most of the tests involve measuring how much air you can breathe in (inhale) and breathe out (exhale).
Medical imaging could provide important information on the symptoms and exercise capabilities of patients with COPD, which may lead to better treatments. The results showed that in mild-to-moderate COPD patients with modestly abnormal lung function test results, MRI measurements of emphysema were strongly correlated with exercise limitation. COPD is a progressive disease of the lungs that affects approximately 65 million people worldwide.

My place was in the chair shown above, take the tube in my mouth (a sterile mouthpiece that is attached to a spirometer shown as black in the picture), seal tight with my lips and wear a nose clip.. I was instructed to breath normally and when prompted, take in a full deep breath and expel it forcefully and completely. Thats harder than I expected especially the last part when there is very little left to expel. I repeated this a couple of times. I think this was for volume, capacity and flow.. Then I was instructed to breath normally, take a deep breath and expel it completely. In this case, I was not required to expel forcefully but completely. There was a small amount of nitrogen in the mix which passes into the blood stream in a comparable path as oxygen. The amount of nitrogen is measured before and after.

I was only there for about 2 and a half hours which is not the norm for a challenge but they did take good care of me. I had an IV, they took blood pressure, body temp, pulmonary function test and heart rate. I took Lactaid and then drank milk straight up (yuck!) and I was perfectly fine. Mind you, it was really nerve-racking because there were four other people getting challenged in the same room as me. We were all lined up with our IVs and every so often the nurse would go around and ask how everyone felt so when one person said they had an itchy mouth I was like, hmm, do I have an itchy mouth??? But I managed to keep my cool and I was ok. Just a bit of a stomach ache when I got home. When I got back to the car with my mom I bawled my eyes out because I was so happy ...

There is evidence that gastro-oesophageal reflux can cause apnoea in infancy and chronic respiratory symptoms in children of all ages. This study aimed to investigate its importance in infants with chronic respiratory symptoms; infants with other symptoms were also studied to clarify the relationship. Fifty infants with chronic respiratory symptoms, 32 with apparent life threatening events and 25 with vomiting were studied. Forty-seven, 29 and 23 respectively underwent a twenty-four hour pH study for assessment of gastro-oesophageal reflux and 44, 16 and 7 had their respiratory function measured. For all these and 23 healthy controls a family background and symptom questionnaire was completed. A comparison of the results of pH studies and respiratory function tests between the three groups was made and the possible influences of background characteristics were assessed. The relationship between the results of pH studies and respiratory function tests within the groups was also investigated. ...

The Pulmonary Function Laboratory at Tufts MC in Boston evaluates lung function in patients to aid in the diagnosis of respiratory conditions.
What is a Pulmonary Function Test (PFT)?. Pulmonary function tests are a broad range of tests that measure how well the lungs take in and exhale air and how efficiently they transfer oxygen into the blood.. Spirometry measures how well the lungs exhale. The information gathered during this test is useful in diagnosing certain types of lung disorders, but is most useful when assessing for obstructive lung diseases (especially asthma and chronic obstructive pulmonary disease, COPD).. Lung volume measurement detects restrictive lung diseases. In this set of diseases, a person cannot inhale a normal volume of air. Restrictive lung diseases may be caused by inflammation or scarring of the lung tissue (interstitial lung disease) or by abnormalities of the muscles or skeleton of the chest wall.. Testing the diffusion capacity (also called the DLCO) permits an estimate of how efficiently the lungs transfer oxygen from the air into the bloodstream.. How the test is performed?. In a spirometry test, a ...
Risk factors for chronic obstructive pulmonary disease among never-smokers in Korea Seok Jeong Lee,1 Seo Woo Kim,1 Kyoung Ae Kong,2 Yon Ju Ryu,1 Jin Hwa Lee,1 Jung Hyun Chang1 1Division of Pulmonary and Critical Care Medicine, Department of Internal Medicine, 2Department of Clinical Trial Center, School of Medicine, Ewha Womans University, Seoul, Republic of Korea Background: Chronic obstructive pulmonary disease (COPD) patients include those who have never smoked. However, risk factors other than smoking in never-smokers have not been elucidated sufficiently. This study investigated the risk factors for COPD among never-smokers in Korea using population-based data. Methods: The data were retrieved from the Korean National Health and Nutrition Survey IV conducted from 2007 to 2009. Among subjects aged 40 years or older who underwent appropriate pulmonary function tests, never-smokers not diagnosed with asthma and not showing a restrictive pattern on pulmonary function tests were enrolled. Risk factors
Lung function testing, performed by Respiratory Therapists, evaluates how well lungs work. The tests determine how much air lungs hold, how quickly air is moved in and out of the lungs, and how well the lungs add oxygen and remove carbon dioxide from the blood. The tests have the capability to diagnose lung diseases and measure the severity of lung problems. A Spirometry measures how much and how quickly air is moved in and out of the lungs. Gas diffusion tests measure the amount of oxygen and other gases that cross through the lungs, which evaluates how well gases are being absorbed into blood from the lungs. Inhalation challenge tests are given to patients to determine if they have asthma. Pulmonary Function (PF) testing is ordered by physicians to screen for the presence of obstructive and restrictive lung diseases, and to evaluate patients prior to surgery. Testing at the PF lab may also include arterial blood gas sampling and exercise oximetry (oxygen level) testing. For more information, ...
The objective of this study is to investigate whether rituximab (RTX), a drug commonly prescribed in patients with rheumatoid arthritis (RA) or inflammatory myositis, is associated with subclinical interstitial lung disease (ILD). Surrogate markers for interstitial lung diseases are a decrease of the forced vital capacity (FVC) and/or the diffusing capacity of the lung for carbon monoxide (DLCO). However, the measurement of these lung function parameters is indicated as regular follow-up examinations during the treatment with RTX according to the principles of good clinical practice. We will perform pulmonary function testing (spirometry) including measurement of the DLCO in patients with RA, who are going to be treated with RTX. A baseline lung function measurement will be performed immediately before RTX therapy is started. Follow-up measurements will be performed at 2 weeks, 4 weeks, 8 weeks and 6 months after initiation of RTX therapy. A reduction in forced vital capacity (FVC) of ,10% or ...

Abstract : ABSTRACT The prevalence of atopic diseases in developed countries has increased in recent years. The reasons for this increase are not clear. It is assumed that the decrease in infections and immunization programs may have contributed to the increase in the prevalence of atopic diseases. The aim of the present study was to examine whether there is a correlation between atopy and exposure to tuberculosis in addition to the factors that affect the correlations if any. A total of 93 cases followed up with atopic asthma diagnosis were included to the study as the atopy group and 111 healthy individuals were included as the control group. All cases were evaluated for atopic symptoms (skin, nasal and ocular complaints), allergy tests, eosinophilia and total IgE level, respiratory function test, PPD Test. It was observed when all cases were evaluated that the atopic symptoms (skin, nasal and ocular complaints), allergy tests, eosinophilia and total IgE levels were higher at a statistically ...

Thirteen patients with lymphocytic interstitial pneumonitis were seen at the Mayo Clinic from 1966 through 1976. The group included nine women and four men, with a mean age of 50.7 years. Their primary complaints were cough, dyspnea, and loss of weight. Chest roentgenographic features were predominantly basilar, coarse interstitial-alveolar infiltrations. Pulmonary function studies showed restrictive ventilatory impairments with a low CO diffusing capacity in all 13 patients. Lung biopsies in all cases showed diffuse interstitial infiltrations, consisting of mature lymphocytes and plasma cells. Ten of the 13 patients had an associated dysproteinemia, including two patients with hypogammaglobulinemia. Three patients had coexistent Sjögrens syndrome, including two with localized amyloidosis. Although lymphocytic interstitial pneumonitis is a histologically distinct pulmonary lesion, it occurs with a variety of immune disorders. ...
Smoking during pregnancy remains a major public health problem as at least 12% of pregnant women cannot quit smoking during pregnancy. This addiction is the largest preventable cause of childhood respiratory illness, including asthma, and children whose mothers smoked during pregnancy show lifetime decreases in pulmonary function. Smoking is a unique morbidity in that it is addictive, heavily advertised and recent genome studies show there are genotypes that significantly increase the likelihood of being unable to quit. Teen pregnancy, low income, low education, and living with another smoker are important factors increasing the odds of smoking during pregnancy. Pulmonary function tests done shortly after birth in babies born to mothers who smoked during pregnancy show decreased pulmonary function as measured by decreased respiratory flows and respiratory compliance and altered tidal breathing patterns. These changes can still be measured even after the infants have reached adulthood. Multiple ...

The study was planned to assess the effect of salbutamol on pulmonary function tests in exercise induced bronchospasm. Eighty children (40 control and 40 mild to moderate asthmatic) in the age range of 10-16 years exercised for 6 minutes on bicycle ergometer at the speed of 35kmph in an air conditioned laboratory. PFTs were recorded 5 minutes after exercise challenge. This was followed by sulbutamol inhalation (200 pg) by metered dose inhaler. PFTs were again recorded 20 minutes after salbutamol inhalation. There was highly significant ( ...
Many tests of lung function have been developed. Each provides slightly different information about how well your lungs are working. Pulmonary function tests are painless and noninvasive. They are performed using a machine called a spirometer. By breathing into the spirometer, your doctor can measure your lung volume and your ability to move air in and out of your lungs in a certain period of time. Your results are compared with typical findings of a healthy person your age and similar height. Your doctor can then determine to what extent your lung function is diminished. Sometimes, tests are repeated after you have been given a bronchodilator medication. This is to see if your results improve with this type of treatment. Pulmonary function measures include:. ...

RATIONALE AND OBJECTIVES: Hyperpolarized (3)He magnetic resonance imaging (MRI) ventilation abnormalities are visible in ex-smokers without airflow limitation, but the clinical relevance of this is not well-understood. Our objective was to phenotype healthy ex-smokers with normal and abnormally elevated ventilation defect percent (VDP). MATERIALS AND METHODS: Sixty ex-smokers without airflow limitation provided written informed consent to (3)He MRI, computed tomography (CT), and pulmonary function tests in a single visit. (3)He MRI VDP and apparent diffusion coefficients (ADCs) were measured for whole-lung and each lung lobe as were CT measurements of emphysema (relative area [RA] with attenuation ≤-950 HU, RA950) and airway morphology (wall area percent [WA%], lumen area [LA] and LA normalized to body surface area [LA/BSA]). RESULTS: In 42 ex-smokers, there was abnormally elevated VDP and no significant differences for pulmonary function, RA950, or airway measurements compared to 18 ex-smokers with
In a clinical study, pulmonary function was studied in 1430 Boston fire fighters during the period 1970 to 1972.

These function tests can show how well your lungs are working. There are a number of different test options. These tests are painless and non-invasive. You will be asked to breathe into a tube called a spirometer. It will measure how much air your lungs can hold. It will also measure your ability to move air in and out of your lungs in a certain period of time. Your results are compared with typical findings of a healthy person your age and similar height. All of this information will show how much your lung function has declined. Tests may also be done after you have been given certain medication. This is to see if this type of treatment is effective for you. Pulmonary function measures include:. ...

Blenoxane - What are effects from the bleomycin? Lung function... An important side effect to be aware of with bleomycin is its effects on lung function. Most oncologists will perform pulmonary function tests (pfts) before administration of bleomycin in order to obtain a baseline. During therapy the pfts will be repeated to monitor for a decrease in lung function. If this occurs, sometimes the dosing of bleomycin will be changed or it will be stopped altogether.

The aim of the study is comparing redistribution of pulmonary perfusion by scintigraphy during early and late periods in cases who had undergone to anatomic lung resections. During the study we have tried to calculate or predict FEV1 values, either before or after resection, which is one of the pulmonary function test. In this study preoperative and postoperative data of patients, who will be operated for lung cancer (n=3) and bronchiectasis (n=3) were collected. During preoperative and postoperative (first and fourth months) periods, arteriel blood gaerses, pulmonary function tests and lung scintigraphy were performed. Postoperative FEV1 values of the patients were calculated either with their preoperative lung function tests or with scintigrafic values. In addition redistribution were investigated according to scintigrafic findings. FEV1 values which were obtained later on (postoperative 1. and 4. months) were higher than preoperatively predicted. FEV1 values measured in the first month, and ...

  • The sources of variation in lung function testing and technical aspects of spirometry, lung volume measurements and D L,CO measurement have been considered in other documents published in this series of Task Force reports 1 - 4 and in the American Thoracic Society (ATS) interpretative strategies document 5 . (
  • Cardiorespiratory fitness was measured by a maximal treadmill test (MTT), and respiratory function was tested by spirometry. (
  • PFTs can include simple screening spirometry, lung volume testing, arterial blood gas analysis, diffusing capacity testing, and cardio-pulmonary exercise testing. (
  • After an outburst of enthusiasm for the numerous lung function measurements introduced during the 1980s and 1990s, the tendency was to limit pulmonary function testing to simple spirometry in most instances, while more comprehensive physiological studies were regarded as unnecessary or even esoteric. (
  • Spirometry is a test that measures the amount of air a person breathes in and out. (
  • During a spirometry test, the person breathes through a tube attached to a computer. (
  • Examines whether Ventolin makes a difference to lung-function values and is performed after Spirometry and/or Lung Volume testing (see tabs above). (
  • This test is easier to perform than spirometry and can even be done in young children. (
  • NIOSH staff evaluated spirometry data supplied by the company on production employees tested from 1998 through 2009. (
  • The majority of the spirometry tests was performed in the years 2004 and later. (
  • We classified spirometry tests for quality and compared the prevalence of abnormalities in acceptable quality tests to national population prevalence, adjusted for the distributions of age, sex, race, smoking, and body mass index in the company's employees. (
  • We calculated declines over time in forced expiratory volume in 1 second (FEV1), a lung function measurement made using spirometry, for employees with more than one spirometry test of acceptable quality, since excessive decline in FEV1 can be an early marker of lung disease. (
  • Using an approach that adjusts for quality of a spirometry monitoring program, reflected by within-person variation, we compared the declines in lung function to a statistically-determined lower limit of normal decline. (
  • The most recent spirometry measurement for 106 employees with at least one spirometry test of acceptable quality showed that 30/106 (28 percent) employees had restrictive abnormalities, 3/106 had obstructive abnormalities, and 1/106 had both restrictive and obstructive abnormalities. (
