METHOD AND APPARATUS TO MONITOR CHANGE IN INSPIRATORY EFFORT USING INTRATHORACIC BLOOD PRESSURE WAVEFORM MORPHOLOGY

摘要

An implantable medical device and associated method detect obstructed inspiration by monitoring an blood pressure signal. A respiration signal is monitored and a phase of respiratory inspiration is detected from the respiration signal. A trend in the pressure signal is measured during the inspiration phase. Obstructed inspiration for the inspiration phase is detected in response to the measured the trend.
