Bilevel NPPV (Noninvasive Positive Pressure Ventilation)

Bilevel NPPV (Noninvasive Positive Pressure Ventilation) is a medical technique that helps patients breathe more easily without inserting a tube into their airway. It uses a mask fitted over the face or nose connected to a machine that delivers two levels of air pressure: a higher pressure when inhaling to assist breathing, and a lower pressure when exhaling to make breathing out easier. This approach supports lung function, reduces the effort needed to breathe, and can improve oxygen levels, often used for conditions like COPD or respiratory failure without needing invasive tubes.
