Abstract: The systems and methods include providing oxygenation-ventilation of a patient being monitored or treated with a medical system. The novel systems and methods may be configured to be able to simultaneously treat and/or monitor a patient with both a ventilator and an ECGE system. The novel systems and methods may monitor the patient and/or manage the treatment of a patient with a ventilator-ECGE system.

Abstract: Ventilatory systems and methods are disclosed for detecting weaning readiness of a patient. In one aspect the method includes the steps of collecting patient data; analyzing the collected patient data to generate at least one patient parameter; comparing the at least one patient parameter to predetermined weaning readiness threshold criteria; and providing an advisory proposition to a clinician indicating a readiness of the patient to start a weaning trial if the at least one patient parameter meets the weaning readiness threshold criteria. The weaning trial may additionally or alternatively be automatically executed if the at least one patient parameter meets the weaning readiness threshold criteria.

Abstract: Ventilatory systems and methods are disclosed including a ventilator and at least one sensor in communication with the ventilator. The sensor is configured to monitor a chest wall movement of a patient during ventilation. The ventilator is configured to provide an alarm to a clinician upon detection by the sensor of a threshold change in the chest wall movement of the patient, for example, a threshold change between the monitored chest wall movement and a previously monitored chest wall movement of the patient. The sensor may be located on an exterior surface of the patient's chest and may be, for example, an accelerometer, an optical imaging system, an audio sensor, an electrical impedance sensor or an ultrasound sensor.

Abstract: This disclosure describes systems and methods for monitoring the ventilation of a patient being ventilated by a medical ventilator. The disclosure describes a novel approach for triggering the delivery of a breath to account for cardiogenic artifacts. The disclosure further describes a novel approach for calculating exhaled spirometry to eliminate the effect of cardiogenic artifacts.

Abstract: This disclosure describes systems and methods for compensating for leaks in a ventilation system based on data obtained during periods within a breath in which the patient is neither inhaling nor exhaling. The methods and systems described herein more accurately and quickly identify changes in leakage. This information is then to estimate leakage later in the same breath or in subsequent breaths to calculate a more accurate estimate of instantaneous leakage based on current conditions. The estimated leakage is then used to compensate for the leak flow rates, reduce the patient's work of breathing and increase the patient's comfort (patient-ventilator breath phase transition synchrony).

Abstract: A medical ventilator system and method that triggers, cycles, or both based on patient effort, which is determined from cross-correlating patient flow and patient pressure. The medical ventilator is also controlled such that sensitivity to a patient initiated trigger increases as the expiratory phase of the breathing cycle progresses. The present invention also provides adaptive adjustment of cycling criteria to optimize the cycling operation.
