A BiPAP (Bilevel Positive Airway Pressure) machine is a non-invasive ventilator that helps people breathe by delivering pressurized air through a mask, providing a higher pressure for inhalation (IPAP) and a lower pressure for exhalation (EPAP). This two-level pressure makes it easier to inhale and exhale, treating conditions like COPD, sleep apnea, and respiratory failure by keeping airways open and supporting breathing without tubes. It’s a compact device, similar to a CPAP but with adjustable dual pressures, allowing patients to breathe spontaneously while receiving crucial support.
