What is Sleep Apnea?
Sleep Apnea is a potentially serious sleep disorder in which breathing repeatedly stops and starts.
There are two main types of sleep apnea:
Obstructive sleep apnea: the more common form that occurs when throat muscles relax.
Central sleep apnea: which occurs when your brain doesn't send proper signals to the muscles that control breathing.
Types of PAP Devices
CPAP: Continuous Positive Airway Pressure is the most commonly used PA device. With CPAP, the level of pressure delivered to the airway is the same during both inhalation and exhalation.
Bilevel PAP: With Bilevel PAP, the pressure during inhalation is higher than during exhalation. The pressures needed to control apnea and hypopnea events with Bilevel PAP are sometimes lower than with CPAP. Because some patients have difficulty tolerating high CPAP pressures, Bilevel PAP may be used when pressures required for CPAP are relatively high.
AutoPAP: Auto-adjusting PAP devices automatically vary PAP pressures during the night to the lowest levels required to eliminate apneas and hypopneas. Some patients with OSA may find AutoPAP devices more comfortable to use.
