If a guest is not breathing but has a pulse, what is the immediate action?

When dealing with a situation where a guest is not breathing but has a pulse, the immediate action is to provide rescue breathing. This is because the individual requires oxygen directly to maintain vital organ function, as they are not able to breathe on their own. Administering rescue breaths helps to provide the necessary oxygen to their lungs and ultimately to their bloodstream.

The process involves delivering breaths that are timed and sufficient to maintain a level of oxygenation without initiating full CPR, since the person still has a pulse. Doing this for a short duration, such as two minutes, allows you to give the individual a chance to start breathing on their own or for emergency services to arrive.

In contrast, starting CPR would not be appropriate here because the presence of a pulse indicates that the heart is still functioning, and CPR is intended for situations where the heart has stopped beating. Using an AED is also not suitable since AEDs are generally utilized when there is no pulse. Calling emergency services is important, but it is not the immediate action; rather, it is typically a step that should be taken alongside or after providing timely assistance.
