Abstract

A system for monitoring a patient's condition during anaesthesia includes electrode means 1 for detecting bioelectrical signals containing the spontaneous EMG activity of the patient, means 2 for amplifying these signals, means 3, 6 for distinguishing the spontaneous EMG component signals from said signals and for suitably quantifying them e.g. logarithmically as well as separate means 14, 15 for simultaneously measuring the patient's neuromuscular blockage by stimulating a motor nerve by means of electrical impulses and by measuring the muscular reaction by means of EMG. The EGG and EMG signals may be separated from the signals from the electrodes 1 by filtering. Said quantities are recorded and displayed on real-time basis so that the output information of said spontaneous EMG and that of the muscular paralysation measured by stimulation are displayed by a common display unit 10. <IMAGE>
