The disease is characterized by hypersecretion of mucus accompanied by a chronic (more than 3 months in 2 consecutive years) productive cough. Infectious agents are a major cause of chronic bronchitis.Cross-Sectional Studies: Studies in which the presence or absence of disease or other health-related variables are determined in each member of the study population or in a representative sample at one particular time. This contrasts with LONGITUDINAL STUDIES which are followed over a period of time.Respiratory Muscles: These include the muscles of the DIAPHRAGM and the INTERCOSTAL MUSCLES.Adrenal Cortex HormonesAirway Resistance: Physiologically, the opposition to flow of air caused by the forces of friction.

... (meaning the measuring of breath) is the most common of the pulmonary function tests (PFTs). It measures lung function, specifically the amount (volume) and/or speed (flow) of air that can be inhaled and exhaled. Spirometry is helpful in assessing breathing patterns that identify conditions such as asthma, pulmonary fibrosis, cystic fibrosis, and COPD. It is also helpful as part of a system of health surveillance, in which breathing patterns are measured over time. Spirometry generates pneumotachographs, which are charts that plot the volume and flow of air coming in and out of the lungs from one inhalation and one exhalation. Spirometry is indicated for the following reasons: to diagnose or manage asthma to detect respiratory disease in patients presenting with symptoms of breathlessness, and to distinguish respiratory from cardiac disease as the cause to measure bronchial responsiveness in patients suspected of having ...
Chronic obstructive pulmonary disease (COPD), also known as chronic obstructive lung disease (COLD), and chronic obstructive airway disease (COAD), is a collection of diseases which make breathing gradually more difficult. Symptoms of COPD include difficulty breathing and cough, in particular coughing up lots of phlegm.[1] It is usually caused by smoking cigarettes, and around half of people who smoke for their whole lives will develop COPD.[2] Air pollution can be another cause, particularly in countries where indoor fires are used without ventilation. At the beginning of the disease, the difficulty breathing is only noticeable when exercising, but over many years it gradually becomes worse, until there is difficulty breathing even when sitting or lying down.[3] It can also lead to infections of the lung, which may be serious enough to cause death. The most important step in treating ...
... is a category of respiratory disease characterized by airway obstruction. Many obstructive diseases of the lung result from narrowing (obstruction) of the smaller bronchi and larger bronchioles, often because of excessive contraction of the smooth muscle itself. It is generally characterized by inflamed and easily collapsible airways, obstruction to airflow, problems exhaling and frequent medical clinic visits and hospitalizations. Types of obstructive lung disease include; asthma, bronchiectasis, bronchitis and chronic obstructive pulmonary disease (COPD). Although COPD shares similar characteristics with all other obstructive lung diseases, such as the signs of coughing and wheezing, they are distinct conditions in terms of disease onset, frequency of symptoms and reversibility of airway obstruction. Cystic fibrosis is also sometimes included in obstructive pulmonary disease. Diagnosis of obstructive disease requires several factors ...

... , also known as levalbuterol, is a short-acting β2 adrenergic receptor agonist used in the treatment of asthma and chronic obstructive pulmonary disease (COPD). Evidence does not show that levosalbutamol works better than salbutamol, thus there may not be sufficient justification for prescribing it. The drug is the (R)-(−)-enantiomer of its prototype drug salbutamol. It is available in some countries in generic formulations from pharmaceutical companies including Cipla, Teva, and Dey, among others. Levosalbutamol's bronchodilator properties give it indications in treatment of COPD (chronic obstructive pulmonary disease, also known as chronic obstructive lung disease) and asthma. Like other bronchodilators, it acts by relaxing smooth muscle in the bronchial tubes, and thus shortening or reversing an acute "attack" of shortness of breath or difficulty breathing. Unlike some slower-acting bronchodilators, it is not indicated as a ...

... (COPD) is a type of obstructive lung disease characterized by long-term breathing problems and poor airflow. The main symptoms include shortness of breath and cough with sputum production. COPD is a progressive disease, meaning it typically worsens over time. Eventually everyday activities, such as walking or getting dressed, become difficult. Chronic bronchitis and emphysema are older terms used for different types of COPD. The term "chronic bronchitis" is still used to define a productive cough that is present for at least three months each year for two years. Tobacco smoking is the most common cause of COPD, with factors such as air pollution and genetics playing a smaller role. In the developing world, one of the common sources of air pollution is poorly vented heating and cooking fires. Long-term exposure to these irritants causes an inflammatory response in the ...

Sometimes, diseases like asthma or chronic obstructive pulmonary disease (COPD) make the bronchi get narrower. This makes it harder for oxygen to get to the lungs. This can cause trouble breathing or even respiratory failure, which means the body is not getting enough oxygen to survive.[2][3]. Every part of the body needs oxygen to live. Without enough oxygen, parts of the body - like the brain - will start to die. Finally, a person's heart can stop if they do not get enough oxygen for a long enough time. Albuterol can often keep these things from happening. Often, people with diseases like asthma or COPD are prescribed albuterol inhalers.[3] As soon as they start having trouble breathing, they can use the inhaler to breathe albuterol right into their lungs. The albuterol will stop the bronchi from getting narrower, and will make them wider again. This makes it possible for normal amounts of oxygen to get to the ...

  • The combination of obesity and COPD has not consistently been associated with increasing shortness of breath during exercise or with diminished exercise capacity compared to that of patients with COPD who are of normal weight, and this finding may be due to the type of exercise regimen employed in these research studies. (infectiousdiseaseadvisor.com)
  • Many people with more advanced COPD breathe through pursed lips and this action can improve shortness of breath in some. (wikipedia.org)
  • Shortness of breath is the primary symptom of COPD. (rxlist.com)
  • In the study known as the DIDASCO project, researchers from Katholieke University compared the effectiveness and accuracy of office spirometry and a screening questionnaire as used by primary care physicians to detect early stages of COPD. (hmenews.com)
  • As shown in our study, office spirometry nearly doubled the number of known cases of COPD in our target patient population, which reinforces the need for spirometry testing in general physician practice. (hmenews.com)
  • Screening can be carried out with simple office spirometry. (cfp.ca)
  • A Spanish cohort study of 611 COPD patients found that the British Thoracic Society classification (which is very similar to Box 4) had the optimal sensitivity and specificity against the criterion of all cause and respiratory mortality over 5 years ( Esteban 2009 ). (copdx.org.au)
  • The cumulative mortality was significantly higher in COPD than NLF, and higher in men than women in both groups. (diva-portal.org)
  • The study found that by using spirometry, the gold standard for diagnosing COPD, primary care physicians nearly doubled the number of "known" COPD cases. (hmenews.com)
  • Without the use of spirometry by primary care physicians, nearly half of our patients with COPD will remain undiagnosed. (hmenews.com)
  • Primary care physicians play a key role in the detection of COPD and should be encouraged to learn the technique of spirometry and incorporate the screening method into regular practice. (hmenews.com)
  • Neutrophil elastase constitutes the primary elastolytic mechanism in patients with α 1 -antitrypsin (AAT) deficiency, while in patients with COPD associated with tobacco smoking, a more important role is played by cathepsins and matrix metalloproteinases [ 9 ]. (hindawi.com)
  • After attempting to replicate primary findings in two independent populations (one composed of subjects with asthma and one composed of patients with COPD) and searching for evidence that variants modified expression levels of their respective genes, we found additional evidence to support the involvement of AGFG1 in AHR. (biomedcentral.com)
  • Conclusion Most patients can be classified as having COPD or asthma by primary care physicians. (bjgp.org)
  • In the primary care setting, access to spirometry is often limited by time constraints and difficulty in interpretation, leading to underuse. (bjgp.org)
  • COPD is commonly managed in primary care using inhaled medication, including inhaled corticosteroids (ICS). (isrctn.com)
  • In both studies, symptomatic COPD patients were randomized to once-daily IND/GLY 110 µg/50 µg or twice-daily SFC 50 µg/500 µg. (dovepress.com)
  • In this pooled analysis, IND/GLY demonstrated superior efficacy compared with SFC in patients in the GOLD B and GOLD D subgroups and supported its use in symptomatic COPD patients. (dovepress.com)
  • This cross-sectional study of the general population of Telemark County, Norway, aimed to identify risk factors associated with poor asthma control as defined by the Asthma Control Test (ACT), and to determine the proportions of patients with poorly controlled asthma who had undergone spirometry, used asthma medication, or been examined by a pulmonary physician.

  • For comparison, 15 normal subjects, 16 asthmatics using inhaled corticosteroids/ long-acting β(2)-adrenoceptor agonist(ICS/LABA combination) and another group of patients with COPD were also studied. (ersjournals.com)
  • The amount of time and effort required to screen for COPD in asymptomatic persons (using screening spirometry with or without prescreening questionnaires) is not trivial. (eurekalert.org)
  • A spirometry test is a simple breathing test where you take a deep breath and blow into a machine, which measures how much air comes out and how quickly. (medbroadcast.com)
  • There are certain "normal" values for the amount of air a patient a patient can forcefully exhale in one second from a maximum full breath in (fev! (healthtap.com)
  • the volume of a full breath (tlc), volume of air exhaled in normal breathing (tv or tidal volume), and many others. (healthtap.com)
