I am an asthmatic prone to bronchitis and debilitating migraines induced by sinusitis.
A year and half ago I got pneumonia, chronic bronchitis, and my asthma flared up and stay flared. I was weeks using a nebulizer to get the asthma under control.
My oxygen consumption level was in the low 80 percent range. My heart had to work harder to get the oxygen I needed. As a result my blood pressure rose, and my resting pulse was twenty beats per minute higher. I was listless and constantly tired.
Forced expiratory volume (FEV) measures how much air a person can exhale during a forced breath. My FEV test was one long wheeze. I was a mess.
