Abstract

A method is provided for treating respiration conditions of a patient. The method comprises monitoring or measuring a respiration parameter indicative of a need to modify activity of a baroreflex system of the patient, and controlling a baroreceptor activation device to cause or modify activation of a baroreflex response of the patient in response to the monitoring or measuring of the respiration parameter.

Claims
