Monitors designed for continuous measurement and display of the number of rhythmic expansions (pulsations) of an artery per minute (i.e., pulse rate in beats per minute). These units are hard-wired to the patient at the bedside. These monitors consist of a main electronic unit that is capable of acquiring and processing signals from one or more sensors, a display, and audible and/or visual alarms that are triggered when the patient\'s pulse rate drops below or exceeds preset limits. Most multipurpose and electrocardiography monitors are capable of pulse rate monitoring.
