CPAP (Continuous Positive Airway Pressure) delivers a constant, steady pressure to keep airways open during sleep. BiPAP (Bilevel Positive Airway Pressure) provides two pressure levels: higher when you inhale and lower when you exhale, making breathing easier for some patients. ASV (Adaptive Servo-Ventilation) automatically adjusts pressure support breath-by-breath, mainly used for complex or central sleep apnea.
