Abstract
A method of monitoring depth of muscle relaxation of a patient includes applying a series of stimulations to a nerve of a patient and measuring muscle responses thereto. A maximal stimulus current, a supramaximal stimulus current, and/or a submaximal stimulus current are determined based on the muscle responses, wherein the maximal stimulus current is a current at which a maximal muscle response is produced from stimulating the nerve, the supramaximal stimulus current is greater than or equal to the maximal stimulus current, and the submaximal stimulus current is less than the maximal stimulus current. A first set of stimulations are applied to the nerve of the patient. Either the supramaximal stimulus current or the submaximal stimulus current are then selected for a subsequent series of stimulations based on the measured muscle responses to the first series of stimulations, and the subsequent series of stimulations are performed accordingly to monitor the patient's depth of muscle relation.
