CPR has to be done on a hard surface or else the pressure of the compression continues through the body and into the soft surface beneath (such as a bed), which has no effect on circulating blood or oxygen.
You do not need to be a professionalrescuer to perform CPR. If CPR is being done correctly, confirm 911 has been called. Ask if the person needs a rest and you take over CPR. If CPR is being done incorrectly, ask the person if you can take over CPR. If you are in a setting where you have a duty to respond or take action (as a professional rescuer), you are the more advanced person so you should assess the situation and determine what needs to be done next. Is the person doing CPR correctly? Is the scene safe? Do you need to call your headquarters? Are there any other victims? Follow your protocols.
