A **BiPAP (Bilevel Positive Airway Pressure) Machine** is a non-invasive ventilation device similar to a CPAP machine but offers a more advanced form of respiratory support. While a CPAP machine delivers a single, constant pressure, a BiPAP machine provides **two distinct pressure settings**: a higher pressure during inhalation (IPAP) and a lower pressure during exhalation (EPAP). This bi-level pressure system makes it easier for patients to exhale against the airflow, which can be more comfortable and tolerable for individuals who find CPAP difficult to use, or for those with more complex respiratory conditions such as central sleep apnea, certain types of COPD, or neuromuscular diseases. By assisting both inspiration and expiration, the BiPAP machine helps improve ventilation, reduce the work of breathing, and ensure adequate oxygenation, leading to better sleep quality and overall respiratory health outcomes.
