Abstract:
1. A method comprising: administering one or more treatments, wherein the one or more treatments change at least one member of the group consisting of ventilation rate, blood carbon dioxide concentration, blood oxygen concentration and blood pH; acquiring a first electroneurogram of carotid sinus nerve activity; analyzing the first electroneurogram to establish one or more relationships between carotid sinus nerve activity and at least one member of the group consisting of ventilation rate, blood carbon dioxide concentration, blood oxygen concentration and blood pH, wherein establishing the relationship comprises filtering the first electroneurogram; providing the one or more established relationships between carotid sinus nerve activity and at least one member of the group consisting of ventilation rate, blood carbon dioxide concentration, blood oxygen concentration and blood pH; acquiring a second electroneurogram of carotid sinus nerve activity; based on the providing the one or more established relationships and the acquiring the second electroneurogram, analyzing the second electroneurogram for at least one member of the group consisting of a decrease in ventilation rate, an increase in blood carbon dioxide concentration, a decrease in blood oxygen concentration and a decrease in blood pH; and based at least in part on the analyzing the second electroneurogram, determining if sleep apnea exists.
