If a GiD does not have a pulse, what is the first action you should take?

In a situation where you determine that a guest in distress (GiD) does not have a pulse, the priority is to begin CPR immediately. This is crucial because the absence of a pulse indicates that the heart is not effectively circulating blood, which can lead to brain damage and death in a very short time. By beginning CPR, you are providing artificial circulation and oxygenation to vital organs, significantly increasing the chances of survival until professional medical help arrives.

Initiating CPR also helps to maintain blood flow to the brain and heart, which is essential for preventing irreversible damage. CPR is a rhythmic compression of the chest that stimulates the heart and enables oxygen to circulate to the body's critical organs. The sooner CPR is commenced, the better the outcome for the individual.

While calling for help is important, it is typically done after assessing the scene, and the unavailability of a pulse takes immediate precedence. Checking for breathing is also necessary but is secondary to the immediate initiation of CPR when a pulse is absent. Rescue breaths are part of CPR but should be provided after chest compressions have started or during the resuscitation process. Thus, the correct action to take first in this emergency situation is to commence CPR.
