Can you explain the significance some of the abbreviations that appear on a spirometry printout? (E.g., “FVC” and “…25%-75%”.
Barry Make, MD– FVC refers to the forced vital capacity and that is the deepest breath a person can inhale or exhale. FEV1 is the amount of air that a person can exhale in one second after completely filling his/her lungs. The FEV1/FVC ratio is the value of the FEV1 expressed as a percentage of the forced vital capacity. That is, the percent of the deepest breath a person can inhale that he/she can blow out in one second. The FEV1 is the most common measure of obstruction to airflow as can be seen with asthma and COPD.Question: I have had COPD (emphysema) for the past 20+ years and each year my lung capacity decreases. Weather changes are increasingly harder to deal with and exercise becomes harder. I have had the top lobe of the right lung removed and have had bypass surgery on 7 arteries. I have heard there may be several new meds on the market in other countries that may bring relief and possibly improve the lung functions.
