Tiered therapy for respiratory oscillations characteristic of Cheyne-Stokes respiration
First Claim
1. A method comprising:
- at a time corresponding to patient rest and in the absence of sleep apnea, delivering a maintenance therapy that aims to prevent sleep apnea, the maintenance therapy comprising cardiac overdrive pacing at a first overdrive rate in excess of a cardiac base rate, a cardiac paced rate or a cardiac intrinsic rate, where the overdrive pacing rate corresponds to an interval between atrial or ventricular pacing pulses;
sensing information during delivery of the maintenance therapy;
based at least in part on the information, determining if apnea comes into existence during delivery of the maintenance therapy; and
if apnea comes into existence, stopping delivery of the maintenance therapy and delivering a termination therapy comprising overdrive pacing at a second overdrive rate in excess of the first overdrive rate.

Abstract
An exemplary method includes delivering a maintenance therapy that aims to prevent occurrence of apnea, sensing information, based at least in part on the information, determining if apnea exists and, if apnea exists, delivering a termination therapy that aims to terminate the apnea. An exemplary implantable device includes an input for information pertaining to respiration and control logic to call for overdrive pacing at a first rate that aims to minimize occurrence of a respiratory condition, to analyze the information for occurrence of the respiratory condition and, upon occurrence of the respiratory condition, to call for overdrive pacing at a higher rate. Other exemplary methods, devices, systems, etc., are also disclosed.

12. A method comprising:
-
at a time corresponding to patient rest and in the absence of hypopnea, delivering a maintenance therapy comprising cardiac overdrive pacing at a first overdrive rate in excess of a cardiac base rate, a cardiac paced rate or a cardiac intrinsic rate, that aims to prevent occurrence of hypopnea; sensing information during delivery of the maintenance therapy; based at least in part on the information, determining if hypopnea comes into existence during delivery of the maintenance therapy; and if hypopnea comes into existence, stopping delivery of the maintenance therapy and delivering a termination therapy that aims to terminate the hypopnea. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21)
