Condition: Obstructive sleep apnea is a condition where the back of the throat closes and prevents breathing. Contributing factors include the structure of the throat which is influenced by how we develop and being over weight. Central sleep apnea is a condition where the brain does not send a signal to the lungs to breath. They are treated differently. See your physician asap if you have this problem.

Apnea = Suffocation: Like being underwater; unable to breathe. When the co2 in blood gets too high, you blast to surface for a big gasp of air. Osa occurs when airway is blocked during sleep, muscles flaccid/paralyzed. When co2 is too high, brain enters crisis mode, lightens the level of sleep to permit active muscle control and permit a big gasp to replenish o2, then back to deep sleep to do it again. Get osa treated.
