A BiPAP machine is a type of non-invasive ventilator that helps people with breathing difficulties. It delivers two levels of air pressure: a higher pressure when the person inhales and a lower pressure when they exhale. This makes it easier for individuals with conditions like sleep apnea or chronic obstructive pulmonary disease (COPD) to breathe comfortably during sleep or while resting. The machine consists of a motor, a mask, and a tube that connects them. The mask fits over the nose or mouth, ensuring that the air is delivered directly to the user. BiPAP therapy can improve sleep quality and overall health by providing consistent airflow and reducing the effort needed to breathe.
