Final answer:
CPR should be paused when the AED is ready to be used, which means after it's turned on, pads are applied, and it prompts to stop for rhythm analysis. Continue CPR until those points and resume immediately after the defibrillation process unless advised otherwise.
Step-by-step explanation:
You should stop compressions when the AED (Automated External Defibrillator) is ready to be used, which is typically once it is powered on, the adhesive pads are applied to the patient's chest, and the device instructs you to stop CPR so it can analyze the heart rhythm.
During a cardiac emergency, CPR (cardiopulmonary resuscitation) is critical to maintain blood circulation when the heart stops beating. Proper CPR consists of chest compressions at least 5 cm deep and at a rate of 100 compressions per minute. If an AED arrives, it is important to integrate its use into the resuscitation process properly. The AED is designed to be used by both healthcare professionals and laypersons, and it functions by analyzing the patient's heart rhythm to deliver a shock if necessary. When another rescuer arrives with an AED, you should continue chest compressions until the AED is set up and ready. Once ready, follow the AED's audible instructions, which will typically command you to cease CPR momentarily while it analyzes the patient's heart rhythm.
It is only at this point, when the AED is actively assessing the need for a defibrillation shock, that you should stop compressions. After the shock is delivered, or if no shock is advised, you should resume CPR immediately until emergency medical services take over, the patient shows signs of recovery, or you are otherwise instructed by the device or a healthcare professional.
