1. A method for monitoring the ventilation of a patient being ventilated by a medical ventilator system, the method comprising:
- monitoring at least one respiratory parameter to determine at least one monitored respiratory parameter of a patient being ventilated by a medical ventilator system;
monitoring a pulse rate of the patient with a pulse rate monitoring device;
determining one or more potential cardiogenic artifacts in the at least one monitored respiratory parameter;
correlating the potential cardiogenic artifacts with the pulse rate of the patient to verify cardiogenic artifacts in the at least one monitored respiratory parameter; and
removing the verified cardiogenic artifacts from the at least one monitored respiratory parameter to provide at least one adjusted respiratory parameter.

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.
