Auto BiPAP machine, also known as auto-adjust bi-level positive airway pressure BiPAP device, is a type of non-invasive ventilation (NIV) used to treat respiratory disorders such as sleep apnea and chronic obstructive pulmonary disease (COPD). It facilitates breathing by transmitting air pressure with a mask to help keep the airway open. The "Auto" feature allows the device to automatically adjust the pressure settings as needed, based on the patient's breathing pattern and other factors such as airflow resistance. This can provide a more comfortable and effective treatment as the pressure can change in real time according to the patient's needs.
