BiPAP (Bilevel Positive Airway Pressure) is a type of non-invasive ventilator machine used for breathing difficulties or respiratory issues during sleep. Its main functions are: Providing air at two different pressures. IPAP (Inspiratory Positive Airway Pressure): Provides higher pressure during inhalation to help air enter the lungs easily. EPAP (Expiratory Positive Airway Pressure): Provides lower pressure during exhalation to make breathing out easier. Conditions where BiPAP is used: Sleep Apnea, COPD (Chronic Obstructive Pulmonary Disease), Asthma or severe breathing difficulties, Respiratory muscle weakness (e.g., neuromuscular disease).
