Assignee: KONINKLIJKE PHILIPS N.V.
Field: Medical technology (Instruments)
Classification: CPC A  G | IPC A  G

Claim 0:
1. A respiratory monitoring system, comprising:
a mechanical ventilator configurable to perform a ventilation mode that includes an inhalation gas delivery phase and provides extrinsic positive end-expiratory pressure (PEEP) at a PEEP level during an exhalation phase;
a breathing tubing circuit including:
a patient port,
a gas inlet line connected to supply gas from the mechanical ventilator to the patient port,
a gas flow meter connected to measure gas flow into lungs of the patient,
a pressure sensor connected to measure gas pressure at the patient port, and

at least one processor programmed to:
compute a proxy pressure comprising an integral of gas flow into the lungs measured by the gas flow meter; and
trigger the inhalation gas delivery phase of the ventilation mode when the proxy pressure decreases below a trigger pressure threshold.
