1. A device for detecting periodic breathing, the device comprising:
- an input for receiving sensor signals representative of one or more physiologic parameters associated with respiration;
signal conditioning circuitry in communication with the input to condition the sensor signals; and
a data processor in communication with the sensor signal conditioning circuitry, the data processor configured to produce an output as a function of the conditioned sensor signals.

Abstract
A system and method for monitoring in a patient includes producing sensor signals representative of a physiologic parameter associated with respiration. A periodic breathing cycle is detected based on the sensor signals. An output is produced as a function of the cycle length.
