PAP Therapy is the first & most effective treatment option for Obstructive Sleep Apnea. There most common types of PAP are listed below. Please note, each type of machine has its own purpose. A board certified sleep physician must determine which form of therapy is best suited to treat your sleep disorder.
CPAP Continuous Positive Airway Pressure
CPAP is the most common treatment option for sleep apnea. CPAP provides a constant, pressurized flow of air that keeps the airway from collapsing. These machines are set on 1 pressure setting. This pressure setting is determined by having an overnight titration study.
BiPAP Bilevel Positive Airway Pressure
BiPAP machines deliver two levels of pressure: a higher pressure when the patient inhales, a lower pressure when the patient exhales.
APAP Automatic Positive Airway Pressure
Auto Pap machines also use one pressure to treat sleep apnea, however, this pressure setting automatically adjusts with the patient as needed during sleep. Pressure settings typically range between 4-20cm H2O.
ASV Adaptive Servo Ventilation
ASV machines are used by patients who have been diagnosed with Central Sleep Apnea, Mixed Sleep Apnea or Cheynes-Stokes Respiration. ASV therapy must be closely monitored by your physician. A recent study has shown ASV therapy to be harmful in patients who have been diagnosed with chronic heart failure & with a reduced left ventricular ejection fraction (≤ 45%).
