IPAP stands for which parameter in positive airway pressure therapy?

• A. Intermittent Positive Airway Pressure
• B. Inspiratory Positive Airway Pressure
• C. Inhalation Pressure Airway
• D. Intrathoracic Pressure Airway

Answer: (B)

IPAP is the pressure applied during the inhalation phase of positive airway pressure therapy to assist breathing. In devices like BiPAP, there are two pressures: IPAP and EPAP. IPAP is higher and provides inspiratory pressure support, increasing tidal volume and reducing the work of breathing, while EPAP helps keep the airways open during expiration. The term directly describes this inspiratory pressure function, so it stands for Inspiratory Positive Airway Pressure. The other options don’t fit standard terminology in this therapy setting.
