AutoBiPAP

AutoBiPAP, short for automatic bilevel positive airway pressure, is a noninvasive ventilation mode that automatically adapts two pressures, IPAP and EPAP, to the patient’s needs during sleep or rest. Unlike fixed BiPAP, autoBiPAP uses an on-board algorithm to titrate pressure in response to detected obstructive events, airway resistance, flow limitation, leaks, and sometimes snoring. The goal is to provide adequate pressure support to resolve obstructive apneas and hypopneas while using the lowest effective pressures to improve comfort and adherence. The device may also adjust to maintain adequate ventilation in conditions such as obesity hypoventilation or nocturnal hypoventilation from neuromuscular disease, though usage varies by clinical indication.

AutoBiPAP devices are primarily prescribed for sleep-disordered breathing and some forms of chronic respiratory failure. They are used at home or in hospital settings under clinician supervision. Common features include ramp start, leak compensation, humidity control, data recording, and programmable backup rate in certain models. The therapy requires proper mask fit and humidification; leaks can affect performance and comfort. Potential limitations include insufficient control of central sleep apnea, complex ventilation needs (for example ASV), or intolerance to mask interface. Side effects can include nasal congestion, dry mouth, sinus issues, and aerophagia. Selection of autoBiPAP versus fixed BiPAP, CPAP, or other noninvasive ventilation modalities depends on the patient’s diagnosis, tolerance, and response to initial therapy.
