Age Related Decline In Lung Function
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

In chf, what predicts recovery verses continued decline most reliably? Is it probnb levels declining and ef increasing, exercise tolerance? Confused
Different issues: Falling ntprobnp (or just bnp) indicates improved compensation but rising ef indicates true improvement in cardiac condition. For instance, someone with an ef of 10% may receive medication and ntprobnp will fall from 10, 000 to 5, 000 as they feel better. But someone with a viral cardiomyopathy may get no treatment but, in time, their ef may rise from 30% to 50%. Exercise tolerance poorly predicts. ...Read moreSee 1 more doctor answer

Your smoking history is significant and I hope that you have quite smoking and will avoid inhaling smoke. Your follow up study should include testing with and without a bronchodilator. This will help your physician determine responsiveness to the medication. ...Read moreSee 2 more doctor answers
