Abstract: A method and system for monitoring neuromuscular blockade in patients during surgical procedures. A stimulator provides stimulation to a nerve of the patient, such as train-of-four (TOF). Following such stimulation, the system and method creates a predicted recovery trend for the patient that is based upon measured recovery trend and a recovery model. The recovery model estimates a recovery trend for the patient based on initial model parameter values. The recovery model creates a predicted recovery trend that is used to estimate a recovery time for the patient. The trend values from the patient are monitored and compared to the predicted trend values throughout the operation as long as the NMT measurement is on. During recovery, the recovery model and recovery time estimates are updated based on the recovery trend being formed from measurements of the patient.
