Methods And Systems For Monitoring A Ventilator Patient With A Capnograph
First Claim
Patent Images
1. A method for monitoring the ventilation of a patient being ventilated by a medical ventilator-capnograph system, the method comprising:
- monitoring a pulse rate of a patient being ventilated by a medical ventilator-capnograph system with at least one of a flow sensor, a pressure sensor, a cardiac monitor, and an oximeter;
monitoring the patient with a capnograph, the capnograph monitors an amount of carbon dioxide in respiration gas from the patient to derive a capnogram;
determining potential cardiogenic artifacts of the capnogram;
correlating the potential cardiogenic artifacts of the capnogram with the pulse rate of the patient to verify cardiogenic artifacts of the capnogram; and
removing verified cardiogenic artifacts of the capnogram.

12. A medical ventilator-capnograph system, comprising:
-
a pneumatic gas delivery system, the pneumatic gas delivery system adapted to control a flow of gas from a gas supply to a patient via a ventilator breathing circuit; at least one sensor, the at least one sensor monitors a pulse rate of the patient; a capnograph, the capnograph monitors an amount of carbon dioxide in respiration gas from the patient in the ventilator breathing circuit to generate a capnogram; a correlation module, the correlation module is adapted to identify potential cardiogenic artifacts of the capnogram, correlate the potential cardiogenic artifacts with the pulse rate of the patient, and remove verified cardiogenic artifacts of the capnogram; and a processor in communication with the pneumatic gas delivery system, at least one sensor, the capnograph, and the correlation module. - View Dependent Claims (13, 14, 15, 16, 17)
