How to determine if you have obstructive sleep apnea hypoventilation syndrome

When patients present with sleep snoring with recurrent apnea, they should be suspected of having OSAHS and should go to the hospital for sleep breathing monitoring.
After the doctor’s examination, if the patient has more than 30 repeated episodes of apnea and hypoventilation during 7h of sleep per night, or apnea hypoventilation index (AHI) ≥ 5 times/h; the apnea event is mainly obstructive, accompanied by snoring, sleep apnea, daytime drowsiness and nighttime awakening, the patient can be judged to have OSAHS.
