Normal Lungs Vs Asthma Lungs
How likely is it, that I still have asthma, when my peakflow are normal? Is it possible to have significant inflammation in lungs with normal peakflow
Deoxygenated blood enters the lungs from the right side of the heart and travels to the lungs. When you inspire, oxygen flows into the lungs, transverses the capilliares and attaches to hemoglobin down a gradient. At the same time, co2 diffuses into the capilaries and is expelled with exhalation. Oxygen rich blood then flows to the left side of the heart and into the ...Read more
October 2012 I had a virus that went to my chest. 4 months later my asthma is worse than ever and my lungs are damaged. How do I get back to normal?
Daily exercise!: Good morning, the surface lining of our airway protects us from the effects of environments and agents we are constantly exposed to. An infection by a virus can destroy this layer, exposing the underlying nerves, which sends signals to contract and reduce the airflow, causing cough and wheezing. Daily exercise can reduce airway tone, along with inhaled medications. Follow instructions of doctor. ...Read more
Yes: It goes the other way around. A person who is wheezing from asthma has partial obstruction to the airflow when he is breathing, and therefore will get lower than normal results on lung function testing. The testing measures the lung problem, and thus shows lower function when the lung is functioning lower. ...Read more
I am diagnosed with bronchitis or inflamed lungs every 2 months. I am always tired and catch ill easily. Non smoker, no asthma, no allergy. Normal?
M.D. visit: Frequent lung infections/non specific inflammation may be related to a number of conditions. If there is a retained aspirated material, reflux and aspiration into the lung, TB, immunodeficiency, these can be related to this occurrence. I would suggest that you have a chest radiograph, lung function testing and assessment for possible immunodeficiency with lab testing. Physician visit is indicated. ...Read moreSee 1 more doctor answer
4 months after a bad chest virus I have severe asthma symptoms. Is there anything I can do besides take medication? When will my lungs reset to normal
Duration can vary!: Good morning, the surface lining of our airway protects us from the effects of environments and agents we are constantly exposed to. An infection by a virus can destroy this layer, exposing the underlying nerves, which sends signals to contract and reduce the airflow, causing cough and wheezing, especially in those with asthma. Exercise can reduce airway tone, along with inhaled medications. ...Read more
Lung volumes show significantly decreased functional residual capacity, but otherwise normal, what's this mean? Doc says I have asthma but decreased frc online says restrictive disease im scared!
Decrease FRC: Frc is the volume of air present in the lungs at the end of passive expiration. Obesity and posture will decrease the frc. I am imaging you just got a complete pulmonary function test. In asthmatic patient, the FRC can be normal or high if associated with emphysema or more chronic obstructive conditions. Low FRC with normal pft is not diagnostic of restrictive lung disease. Trust your lung doctor. ...Read moreSee 1 more doctor answer

Thin ex smoker 28yo shows hyperinflated lungs in X-ray would it indicate asthma or copd? 12 pack year history. Fev values normal. Odds of emphysema?
Difficult todiagnose: A chest Xray alone cannot give detailed information about whether a patient has asthma vs. COPD. Many factors must be taken into account. A full set of pulmonary function testing in a physician's office with FEV1, FVC, DLCO etc. And a detailed history and physical examination is the first step. ...Read more

I am on oxygen for asthma and altitude, but my levels are over 90 all day. I use it at night. Can I ever stop? Heart and lung tests were normal. Is it harmful to use if not needed?
Depends: The answer depends on the testing you have had done and the pulmonary dr. Following your case. Some people have good pulse ox reading during the day, but when an overnight pulse ox test is performed they 'desaturate' to low levels that are troublesome, thus oxygen is rx'd for night time use. Check with the prescribing dr. On how your condition is doing, and keep going to follow-up appts. Good luck. ...Read moreSee 3 more doctor answers

Shortness of breath with mucus for a year. Doc has said Gerd. Doesn't think asthma. Smoked 10 yrs.25. Lung test normal. Copd? Pneumonia? Just smoking?
Quit smoking: The most obvious answer of course is that you have to stop smoking. There is no benefit from smoking, and as long as you continue to do so, you will be short of breath and have increased mucous and cough. You know this. Smoking makes asthma, GERD and COPD worse if you have them. Smoking causes other serious chronic health problems, such as cancers, stroke, heart disease. Have you tried Chantix? ...Read moreSee 1 more doctor answer

Whether you have asthma or not, you need to be evaluated for your symptoms by an asthma specialist, you may not have the condition. spirometry, sort of lung function testing, or methacholine challenge may be needed.
