IPAP stands for which phrase?

• A. Inspiratory Positive Airflow Pressure
• B. Inspiratory Pressure Airway Positive
• C. Inspiratory Positive Airway Pressure
• D. Inspiratory Positive Air Pressure

Answer: (C)

IPAP is the pressure applied during the inspiratory phase to assist breathing. The standard expansion is "Inspiratory Positive Airway Pressure." Here, “inspiratory” means during inhalation, “positive” indicates pushing air into the airway, “airway” identifies the site of pressure, and “pressure” is the measured force used. The phrase used in clinical practice is precise: it describes the inspiratory pressure support delivered to the patient.

Other wordings don’t fit because they swap or omit a key term. Using “Airflow” instead of “Airway” changes the meaning, and placing the words in a different order or dropping “Airway” yields nonstandard terminology. In practice, IPAP works with EPAP to provide pressure support and influence tidal volume and work of breathing.
