I'm a bit worried because I had COVID about three weeks ago, and my doctor suggested spirometry exercises for my lungs. But I've noticed that when I do spirometry for about 2 minutes, my SpO2 levels drop to like 92, 93, or 94. If I wait for 5 minutes after that, it goes back up to around 98 or 99. I also tried a 6-minute walk, and my SpO2 seems to stay around 96 to 98 during that. Is it normal for spirometry exercises to drop my SpO2 so much? Just for reference, my chest CT score was 12.
spirometer will improve spo2 never decrease it
