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 ...

Background: Although ischaemic heart disease (IHD) and chronic pulmonary diseases, eg COPD, share similar risk factors, the prevalence and rate of diagnosis of airflow limitation (AL) compatible with COPD, and other lung function abnormalities, in patients with IHD are largely unknown.. Methods: In a cross-sectional study conducted in 15 sites across nine European countries (Belgium, France, Germany, Greece, Ireland, Italy, the Netherlands, Spain, and Sweden), we investigated the prevalence of airflow limitation compatible with COPD (defined as post-bronchodilator (BD) FEV1/FVC ,0.70) and other lung function abnormalities in outpatients with documented IHD who were ≥40 years, and current or former smokers. Each participant completed a core questionnaire and performed full pre- and post-BD spirometry. Quality control of spirometry readings was performed by a centralized system.. Results: Up to April 2012, we studied 1803 evaluable IHD patients, 86.0% male, mean±SD age of 65.0±9.8 years. The ...

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.

Pulmonary function tests (PFTs) are noninvasive tests that show how well the lungs are working. The tests measure lung volume, capacity, rates of flow, and gas exchange.
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. This is a test for gas exchange.. The diagnostician running the test commented that my lungs appear to be fully functioning, in great shape and said if all his patients were as good, ...
PFT. This test can be highly variable. The quality of the test can depend on several things. The patient performing the test has to really give it a good effort. Many times this is also dependent on the person administering the test, who must be a good instructor. Also the equipment must be calibrated, and functioning well, no air leaks and also the type of equipment may allow for some variability. Read more... ...

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. ...

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 ...
