What is the recommended starting pressure for BiPAP?

The recommended starting pressure for BiPAP (Bilevel Positive Airway Pressure) is typically around 8/4 cmH2O. This pressure indicates a higher inspiratory positive airway pressure (IPAP) of 8 cmH2O and a lower expiratory positive airway pressure (EPAP) of 4 cmH2O. This configuration is often used because it provides adequate support for patients with respiratory conditions like obstructive sleep apnea by allowing for effective ventilation and maintaining airway patency.

Starting at this pressure allows for sufficient airway pressure to help decrease the work of breathing and improve gas exchange, while not being excessively high, which might discomfort the patient or increase the risk of complications. For many patients, these moderate pressures offer a good balance of comfort and therapeutic effect at the initiation of BiPAP therapy.
