1. A system, comprising:
- an air pressure supply arrangement providing air pressure to a patient'"'"'s airways;
a sensor detecting input data corresponding to a patient'"'"'s breathing patterns of a plurality of breaths; and
a titration device receiving and analyzing the input data to determine existence of breathing disorder and corresponding characteristics, the titration device generating output data for adjusting the air pressure supplied to the patient as a function of an index of different abnormal respiratory events included in the input data, wherein the titration device performs the receiving and analyzing in a collection/analysis period during which no adjustment to the air pressure that is delivered to the patient'"'"'s airways is initiated by the titration device.

Abstract
Described is a system including an air pressure supply arrangement, a sensor and a titration device. The air pressure supply arrangement provides air pressure to a patient'"'"'s airways. The sensor detects input data corresponding to a patient'"'"'s breathing patterns of a plurality of breaths. The titration device receives and analyzes the input data to determine existence of breathing disorder and corresponding characteristics. The titration device generates output data for adjusting the air pressure supplied to the patient as a function of an index of abnormal respiratory events included in the input data.
