First Claim
Patent Images
1. A method for treating a subject comprising the steps of:
- sensing one or more characteristics of breathing;
detecting flow limited breathing from the sensed one or more characteristics of breathing and recording information relating to the flow limited breathing via polysomnography, wherein detecting flow limited breathing comprises sensing an EMG complex of the subject'"'"'s diaphragm and detecting flow limited breathing from a determination of a parameter corresponding to an area under a power spectral density plot of the EMG complex;
identifying at least one cause of the flow limited breathing based on the recorded information;
correlating the at least one cause to an electrical stimulation protocol programmed to treat the flow limited breathing; and
providing electrical stimulation during an existing respiratory cycle according to the protocol to elicit a diaphragm response to thereby reduce flow limited breathing.

Abstract
A device and method for detecting and treating airflow limitations in a subject is provided. Levels of flow limited breathing may be differentiated. Obstruction versus flow limited breathing may be differentiated as well. The EMG complex characteristics may be used to detect obstruction or flow limited breathing. The power spectral density plot of the EMG may be used to detect obstruction or flow limited breathing.
