Abstract:
1. System for treating ventilatory instability, comprising: a sensor adapted to monitor a physiological parameter of a patient; a processor adapted to: (i) identify a ventilatory instability experienced by the patient based on a signal provided by the sensor, (ii) determine a reference point in the patient's respiratory cycle with respect to the ventilatory instability, wherein the reference point is a peak between a crescendo phase and a decrescendo phase in a Cheyne-Stokes Respiration (CSR) cycle of the patient, and (iii) determine a start time for treatment representing a certain instance of time in the respiratory cycle, the start time being: (1) based on a delay value that is based on an estimate of delay of peripheral chemoreceptor response of the patient, and (2) aligned with the reference point; a therapy delivery system adapted to provide a treatment to the patient to counteract the ventilatory instability, wherein the processor causes the therapy delivery system to initiate the treatment the start time, wherein the therapy delivery system is a pressure support system, a gas modulation system, or both, and wherein the treatment includes a ventilatory therapy, a gas modulation therapy, or both.
