According to the New South Wales Government Agency for Clinical Innovation, a BiPAP machine is used to help a patient breathe. It pushes air into the lungs and helps to hold the lungs inflated, allowing more oxygen into the them.
According to the New South Wales Government Agency for Clinical Innovation, BiPAP stands for Bi-Level Positive Air Pressure. A BiPAP machine supports a patient's breathing in the event of cardiac failure, adult respiratory distress syndrome, chronic obstructive pulmonary disease, pneumonia, sleep apnea or any other condition in which a patient cannot breathe properly and needs assistance. It's a small device that's connected by a tube to a face mask worn by the patient. A BiPAP machine maximizes the transport of oxygen into the lungs and blood. BiPAP machines can be used in the Intensive Care Unit, in specialized respiratory wards or at home. It is sometimes used in the place of a ventilator, or a breathing machine.
According to ALS From Both Sides, a BiPAP is a non-invasive ventilatory assist machine. This means that it assists with breathing without inserting a tube into a patient's airway; instead, it has a mask that goes over the patient's face and pushes oxygen into the lungs through the nose.
