Obstructive Sleep apnea (OSA) is a sleep disorder that occurs if a patient’s breathing pattern is abnormal while asleep. There are various factors and medical disorders that can increase the risk of the occurrence of sleep apnea. Sleep apnea can also range in severity. Once sleep apnea is diagnosed utilizing a sleep study ordered by your physician, treatment can be initiated.
