Had spirometry test today and it came out moderately severe obstruction. What does it mean? Is it bad?

PFT: Ask them if they perform a separate test after you inhale a bronchodilator that helps open your airways. Do you smoke? It could mean you have copd (emphysema and /or chronic bronchitis., asthma, reactive airways disease (similar to asthma) or more rare conditions. ...Read more

Spirometry (Definition)

A spirometry is a measurement of velocity (speed) of air coming in & out of the lungs which equals the diameter of the airways. This an indirect measument of the lung function diffeent patterns are posible & direct us as specialist to diagnosed ...Read more

If I have a cold, the spirometry test may result changed?

If I have a cold, the spirometry test may result changed?

Sure: Anything that affects one's breathing can also affect the spirometry test results. A person with underlying asthma symptoms, who catches a cold, will likely display worse spirometry readings due to increased asthma symptoms. ...Read more

How bad does it mean when spirometry results only show the number 300 ml (vital capacity)? What is the average normal value for spirometry test?

How bad does it mean when spirometry results only show the number 300 ml (vital capacity)? What is the average normal value for spirometry test?

Depends on: The predicted normal lung function results are based on age, sex, ethnicity, gender, and height. Thus the normal value varies among individuals. You must have misread your vital capacity since no adult can live with a 300 ml vital capacity. Could it be 3, 000 ml? ...Read more

Talk to ordering MD: The physician that ordered the spirometry should be able to provide the interpretation and what the results mean relevant to your specific symptoms. ...Read more

How accurate is a spirometry test in diagnosing asthma?

Very but..: Asthma is an intermittent disease, thus a relatively normal lung function test on one occasion does not rule out asthma. However it should be abnormal when you have symptoms and the numbers (fev-1) often improves after bronchodilator . As with all tests, a doctor can only make a diagnosis after having obtained your history, performed a physical exam, and then interpret the lung function results. ...Read more

Is bronchospasm asthma an will it come up on a spirometry test?

Is bronchospasm asthma an will it come up on a spirometry test?

Maybe: Asthma occurs when people have excessive bronchospasm triggered by allergens, irritants, some medications or environmental exposures. Bronchospasm is typically acute and may not show up on spirometry if there has not been a recent trigger. In this case a methacholine challenge may be used to induce bronchospasm for diagnosis by spirometry. ...Read more

Dr.Tony l.Wilson my whole spirometry was 83% pred.Value is this COPD stoped smoking since test .

Not necessarily: Levels above 80% are considered normal on spirometry. There is a wide range of normal values. In any case, stopping smoking is an excellent decision and will help your overall health. ...Read more

What does it mean when a spirometry test (lung function) shows a restrictive trend?

What does it mean when a spirometry test (lung function) shows a restrictive trend?

Restrictive change: Restrictive changes mean that you generally can get air in and out but just less (like your lungs are restricted... Like belly is restricted when your belt is too tight). Restrictive changes can be internal based on lung function (scarring, etc) or external factors (like scoliosis or abdominal obesity). ...Read more

I got my lungs checked by 3 spirometry breathing tests and a x-ray. All turned out to be just fine. Is these enough to say my lungs work fine?

I got my lungs checked by 3 spirometry breathing tests and a x-ray. All turned out to be just fine. Is these enough to say my lungs work fine?

Pretty much.: You've had some extensive testing and everything has come back normal. Rather a lot to have had done at your age. You self-report anxiety and difficulty breathing, but the tests you had should have picked up a physical cause for your symptoms. I almost hesitate to say this, but the only other test would be a diffusion capacity test. Mention it to your doctor if you wish ; follow their advice. ...Read more

If you have exercise induced asthma and have a spirometry test, will it most likely show on the results?

If you have exercise induced asthma and have a spirometry test, will it most likely show on the results?

Depends.....: In exercise-induced asthma, spirometry will be normal at rest unless there is bronchospasm at the time of the test. If the test is done post-exercise, it may show obstruction if the exercise induces bronchospasm. Good luck! ...Read more

What pulmonary function test or combination of values on spirometry has best positive predictive value for mortality within a year?

What pulmonary function test or combination of values on spirometry has best positive predictive value for mortality within a year?

FEV1: The forced expiratory volume breathed out in the first second (FEV1) is a strong indicator of mortality over the next year. It should be greater than 1 liter. Everyone is an individual though and this is a guide only. ...Read more

Can a regular spirometry test not big machine show what stage COPD is? I did the small one that u blow into a few times and was told stage 3 COPD ?

Can a regular spirometry test not big machine show what stage COPD is? I did the small one that u blow into a few times and was told stage 3 COPD ?

COPD: There are hand held spirometers that can make a diagnosis of COPD. For stage IIi you needs FEV1/FVC <0.7 and FEV1 between 30-50% so it can be made by the hand held spirometers. https://www.nhlbi.nih.gov/health/health-topics/topics/copd/diagnosis http://www.aafp.org/afp/2008/0701/p87.html ...Read more

Dear dr, my spirometry test show fvc %pred 80. Interpretation: normal. But my doctor wrote mild restrictive ventilatory defect. Need some advice. Tks!

FVC reduced: That likely meant that your lung capacity was reduced. The reduction can be caused by many things but the most common one is being overweight with the excessive weight restricting the lung's expansion. Make sure that you get some follow-up on this. ...Read more

Spirometry: The large airways appear to be within normal limits but the fef25-75 is suboptimal. The fef25-75 is currently the best method to evaluate the small airways of which it appears that you do have some obstruction taking place. ...Read more
