Abstract

A method of treating a patient, comprising: sensing a biological parameter indicative of respiration; analyzing the biological parameter to identify a respiratory cycle; identifying an inspiratory phase of the respiratory cycle; and delivering stimulation to a hypoglossal nerve of the patient, wherein stimulation is delivered if a duration of the inspiratory phase of the respiratory cycle is greater than a predetermined portion of a duration of the entire respiratory cycle.

Claims

1. A method of treating a patient, comprising:

sensing a biological parameter indicative of respiration;

analyzing the biological parameter to identify a respiratory cycle;

identifying an inspiratory phase of the respiratory cycle; and

delivering stimulation to a hypoglossal nerve of the patient, wherein stimulation is delivered if a duration of the inspiratory phase of the respiratory cycle is greater than a predetermined portion of a duration of the entire respiratory cycle.

2. The method of claim 1, wherein the predetermined portion of a duration of the entire respiratory cycle is at least 40% of a duration of the entire respiratory cycle.

3. The method of claim 1, wherein the biological parameter includes impedance.

4. The method of claim 3, wherein analyzing the biological parameter to identify a respiratory cycle includes identifying impedance peaks.

5. The method of claim 3, further comprising comparing an amplitude of the impedance peaks to a threshold.
