I often experience heavy breathing in sleep as explained by my relation who sees that. He has checked using pulse oximeter and the findings are as follows: oxygen saturation goes from 99 to 91 at the same time the pulse rate too drops from 88 to 68. At this point of time I am breathing heavily and then both pulse rate and oxygen saturation returns to normal as 88 and 99 respectively. This happens many times during my sleep. What does this symptom refer to?
Probable diagnosis is obstructive sleep apnea syndrome, pulmonologist opinion is advised to the patient.
