What is the definition or description of: spirometer?

Tests breathing: This device measures a person's ability to breathe in and out -- how much air, how quickly, for how long, how much air is left behind, etc. This provides some information for diagnosis and determining severity of disease (treatment, disability claims). ...Read more

How do I use an incentive spirometer?

Deep slow breaths in: Incentive spirometers aid in opening up the passages and air sacs of the lungs, especially after surgery that requires a ventilator. The device is simple but the technique is key: fully exhale and then slowly inhale through the tube, watching the little flow guide so as not to breath too quickly. Coughing is to be expected(and encouraged). Try to slowly increase your volume to ~ 1200-1500 cc/br. ...Read more

Normal?: The lung function test is dependent on height (gender, age , ethnicity as well) and thus if you were a short person, this may be a normal value. Although you can improve your exercise tolerance and endurance with exercise, there is no way to increase one's total lung capacity (however reversal of obesity would improve the lung capacity). ...Read more

Other than asthma, what else can make you fail a spirometer test?

Other than asthma, what else can make you fail a spirometer test?

Many things: Though "failing" is not a term i would use, there are many other conditions that can show up in a spirometry test. These may include lung obstructions, vocal cord dysfunction, copd, etc. Most of the time these conditions will give results that are not characteristically like asthma but feel like it. Good luck. ...Read more

If the nurse did a spirometer test wrong, is it ok to ask for them to retest before I have a stress test done?

Yes: Not sure how the nurse would have done the test wrong, but if he or she did then this sounds entirely reasonable. Obviously a test done the wrong way will cause misleading results and your doctors should have accurate information to assess your health. ...Read more

I live at a mile above sea level, and decided to use a spirometer to measure my intake of air. I recorded it at 2500ml, should I be concerned?

I live at a mile above sea level, and decided to use a spirometer to measure my intake of air. I recorded it at 2500ml, should I be concerned?

Not sure: Not sure what was measured or how correctly it was done. Lung function and capacity is very dependent upon age / sex and height AND not upon altitude. If you measured Vital Capacity AND measured it correctly you may be at the low end of normal. Vital Capacity is not generally measured without a clinical indication. If you have lung symptoms you should see your doc. ...Read more

I was just diagnosed with pneumonia. What should be value on the spirometer be a goal to reach to know my lungs are better. I am a 40 yr fit female?

I was just diagnosed with pneumonia. What should be value on the spirometer be a goal to reach to know my lungs are better.  I am a 40 yr fit female?

I wouldn't recommend: Ms/Mrs. Lamb, after a true pneumonia, your lungs probably will take some time to recover. However, I usually follow this recovery clinically - which means is based on the absence of fever and progressive improvement in the shortness of breath. You will be coughing while your body cleans itself - remember that cough (and mucus) are like the "sweeper" of the lungs. Unless you have asthma...do you? ...Read more

I use my Voldyne inspired spirometer @ least 3+Times qday. Scared of pneumonia again since last time BUT is it me..makes me feel nauseous/bloated etc?

Interesting....: cannot say in your particular case, but generally, increased abdominal pressure can cause those symptoms. Hiatal hernia, air swallowing are common. Oddly enough, yoga breathing technique or other training in breathing would fix it. Spirometry would also be interesting to see breathing pattern. ...Read more
