BIPAP machines, or bilevel positive airway pressure machines, are designed to assist individuals with breathing difficulties by providing targeted airway support, particularly for conditions like sleep apnea and COPD. Unlike CPAP machines, BIPAP machines operate with two pressure levels for inhalation and exhalation, enabling more effective treatment for complex respiratory issues. Selecting the right BIPAP machine involves consulting healthcare providers and considering features like pressure settings, portability, and mask compatibility for optimal comfort and effectiveness.
