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
determining a start time for delivery of a stimulation to a hypoglossal nerve of the patient by identifying a duration of the inspiratory phase of the respiratory cycle that is greater than a predetermined portion of a duration of an entirety of the respiratory cycle.

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.

11. A method of treating a patient, comprising:
-
monitoring a signal relating to a biological parameter indicative of respiration from a sensing device; evaluating the signal to identify a respiratory cycle; identifying an inspiratory phase of the respiratory cycle; and identifying a start time for delivery of a stimulation to a hypoglossal nerve of the patient, wherein identifying the start time includes comparing the inspiratory phase to the respiratory cycle and further includes determining that a duration of the inspiratory phase is greater than a predetermined portion of a duration of an entirety of the respiratory cycle. - View Dependent Claims (12, 13, 14, 15, 16)

17. A method of treating a patient, comprising:
-
observing a signal indicative of a biological parameter from a sensing device to identify a respiration waveform; identifying a respiratory cycle of the respiration waveform; identifying an inspiratory phase of the respiratory cycle; and setting a start time for delivery of a stimulation to a hypoglossal nerve of the patient by comparing the inspiratory phase to the respiratory cycle and by determining that a duration of a portion of the inspiratory phase is greater than a predetermined portion of a duration of an entirety of the respiratory cycle. - View Dependent Claims (18, 19)
