A member asked:

After a deep breath oxygen climbs to about 97% then rapidly drops to 93% or much less 10 secs later. why? (monitoring for home records)

A doctor has provided 1 answer

Pulse oximetry: is variable depending on multiple conditions: a much better evaluation of your pulmonary functions would be formal spirometry with evaluation of FVC FEV1 and FEV3. Please see a physician for exam and testing.
