What is sleep apnea?
Sleep apnea can be defined as a pause in breathing lasting more than 10 seconds during sleep. During each episode of pause in breathing, the brain of the sleeping person wakes up momentarily to allow breathing to resume. These awakenings, if they are frequent, lead to a fragmented and very poor quality of sleep, even if the person is not aware of it. If left untreated, it can lead to major health problems.

Sleep apnea is diagnosed from a specialized test called polysomnography or sleep study. This test confirms the diagnosis of a sleep disorder, recognizes an associated pathology and guides the therapeutic decision. This is done in the sleep laboratory. It consists of recording different parameters during sleep. You have to sleep with several electrodes or sensors attached to different places on the body. Thereafter, all the data collected are compiled, processed by software, analyzed by a sleep technologist and reviewed by a sleep specialist to establish the diagnosis.
Continuous Positive Airway Pressure (CPAP). PPC means that air is pushed by continuous positive airway pressure to keep them open.
