Summary A laboratory assessment was made of systems used for Continuous Positive Airway Pressurel lntermittent Mandatory Ventilation (C papiimv ) with the Servo 900B and 900C ventilators. Pressure‐volume loops recorded during sine wave oscillation using an external C papiimv system were similar to those found during normal respiration. Pressure‐volume loops using the systems based on the ventilator's inbuilt trigger mechanism were very djflerent. particularly for the 900B. The results were conjirmed by measurements in two infants. The implications of these jindings with reference to the weaning of infants from mechanical ventilation are discussed.
