Abstract:
A system for delivering a flow of breathing gas to an airway of a patient, the system comprising:a gas flow generating system that generates a flow of breathing gas; a patient circuit coupled to the gas flow generating system and adapted to communicate the flow of breathing gas to an airway of a patient; a flow sensor associated with the gas flow generating system or the patient circuit and adapted to measure the flow of breathing gas within the patient circuit and to transmit a flow signal indicative thereof; CSR monitoring means, receiving the flow signal from the flow sensor, for (1) determining peak flows Qpeak(current) therefrom, and for determining whether such a patient's respiratory activity is indicative of Cheyne-Stokes respiration based on the peak flow Qpeak(current); and controlling means for controlling the gas flow generating system so as to cause the breathing gas to be delivered at a sufficient pressure during at least a portion of a breathing cycle to threat Cheyne-Stokes respiration based on an output of the CSR monitoring means.
