Abstract: A neuromuscular test device for assessing a level of neuromuscular blocking agents (NMBAs) in an anesthetized patient includes a stimulation circuit for initiating a muscular stimulus in a muscle structure, and a testing circuit for measuring an activity level responsive to the muscular stimulus. A flexible, closed vessel is responsive to a musculature response for inducing a pressure, and a pressure sensor in communication with the closed vessel generates a pressure signal indicative of the musculature response to the muscular stimulus.
