BiPAP and CPAP are two types of non-invasive ventilation machines designed to help individuals with sleep apnea and other breathing disorders. CPAP delivers continuous positive airway pressure at a constant level, making it effective for most obstructive sleep apnea patients. BiPAP, on the other hand, provides two pressure levels — one for inhalation (IPAP) and a lower one for exhalation (EPAP), which can be more comfortable for some users and beneficial in treating central or complex sleep apnea. Both devices improve breathing during sleep, reduce snoring, and prevent complications related to low oxygen. The choice between CPAP and BiPAP often depends on the severity of the condition, comfort level, and doctor's recommendation.
