Abstract: A restraint system for restraining a user and monitoring the pulse of the user at the time he or she is administered cardiopulmonary resuscitation (CPR). The restraint system prevents the user from harming himself or medical professionals during an emergency situation. The restraint system includes a pair of cuffs connected by a strap, wherein each cuff includes a means for monitoring a user's pulse, such as an electrode, infrared sensor, or other similar device. The cuffs can be secured on the user's wrists, wherein the strap is used to restrain excess arm movement of the user. A display is disposed on the strap, wherein the display is electrically connected to the sensors. The display shows the pulse rate of the user, thereby providing assistance to an emergency medical professional in assessing the user's health status and aiding in the administration of the correct compression rates during CPR.
