What is CPAP Therapy?
CPAP therapy is a treatment that is used to treat obstructive sleep apnea (OSA). Obstructive sleep apnea is a medical condition that causes you to repeatedly stop breathing throughout the night. With OSA, you stop breathing because your throat muscles relax, your airway becomes obstructed (by your tongue or tonsils), and you stop breathing. Each time this happens - which is many times throughout the night - you rouse to begin breathing again. Each time this cycle happens (stop breathing/waking) is referred to as an “apnea event” or apnea.
Obstructive sleep apnea can be mild to severe, depending on how often this cycle occurs:
- Mild OSA: 5-14 apneas per hour of sleep
- Moderate OSA: 15-30 apneas per hour of sleep
- Severe OSA: 30+ apneas per hour of sleep
When you stop breathing and rouse this much throughout the night (anywhere from 40 to hundreds of times throughout the night), the natural result is severe sleep deprivation. As a result, your life may be shorter, unhappier, and less performant than if you treated your sleep apnea.
This is where CPAP therapy comes in. In CPAP therapy, you use a CPAP machine to gently push air into your airway to keep it from collapsing and, in effect, to also keep you breathing and sleeping.
