MONITORING OF NEUROMUSCULAR BLOCKADE USING PHONOMYOGRAPHY

摘要

In a method and device using phonomyography for monitoring the function of at least one muscle of a patient, a stimulator applies muscle-­activating stimulation signals to the patient's muscle via at least one electrode, and a microphone detects phonomyographic signals produced by the patient's muscle in response to the muscle-activating stimulation signals. The microphone has a frequency characteristic adjusted to frequency requirements of the muscle. Also, a signal processor supplies processed muscle function representative data in response to the sensed phonomyographic signals, and a display illustrates the processed muscle function representative data from the signal processor.
