摘要:
The system, method and computer-readable storage medium are for detection of ventilator and patient disconnections using patient lung compliance estimated on both inhalation and exhalation phases of a breath. A ventilator breathing system (10) provides breathing gas to a patient, and includes a gas supply (12), a patient tubing circuit (14) coupled to the gas supply, and a gas monitoring system (16, 18) associated with the patient tubing circuit and configured to monitor at least flow and pressure. A control unit (20) is coupled to the monitoring system and configured to determine a patient disconnection from the system by estimating a patient lung compliance ratio based upon determined volumes of gas delivered during the inhalation phase of the breath cycle and exiting during the exhalation phase of the breath cycle, and monitored pressures in the patient tubing circuit during the inhalation and exhalation phases of the breath cycle.
