You are the attending physician preparing a patient for induction of anesthesia for abdominal cavity revision due to ileus status. Relaxometer, which uses accelerometric evaluation of muscle responses, has been chosen for monitoring neuromuscular blockade. This is the first use of this device. Before starting the measurement of neuromuscular transmission, it is necessary to check the proper placement of the electrodes over the ulnar nerve on the volar side of the forearm and secure the accelerometer to the thumb to accurately monitor the muscle response. What else needs to be checked before starting measurements with this relaxometer?
