A muscle relaxation monitoring apparatus includes a calibration processing section for performing a calibration process that electrically stimulates a nerve which is an observation portion of a subject, by a predetermined stimulation current value at a predetermined stimulation timing, and that acquires a stimulation current value of a supramaximal stimulation exceeding a maximal stimulation of the subject, based on an amplitude peak value of an electric signal that is based on a stimulation response of a muscle due to the electrical stimulation. The calibration processing section performs, when the subject is in an awake state, the calibration process while using a first stimulation timing that is preset, as the stimulation timing, and performs, when the subject is in a muscle relaxation state, the calibration process while using a second stimulation timing that is longer in period than the first stimulation timing, as the stimulation timing.

Muscle relaxation monitoring apparatus and calibration processing method

A patient monitor () acquires a vital sign that is based on a physiological signal of a subject, and an ultrasonic image that is based on a reflected wave of an ultrasonic wave which is irradiated onto the subject. A display section () displays information of the subject. A control section () switches between a first mode in which a screen containing information of the vital sign is displayed on the display section (), and a second mode in which a screen containing the ultrasonic image is displayed on the display section ().
