For patients who experience cardiac arrest, what is the recommended sequence of actions?

The recommended sequence of actions for patients experiencing cardiac arrest begins with quickly calling for help, then performing CPR, and finally using an Automated External Defibrillator (AED) when available. This sequence is critical because time is a crucial factor in cardiac arrest situations.

Calling for help ensures that additional resources and personnel are summoned immediately, which is essential for effective emergency response. Next, starting CPR helps to maintain blood flow to vital organs and increases the chances of survival. The application of chest compressions is vital as it supports circulation during this life-threatening event. When an AED is accessible, providing defibrillation as soon as possible is key, as it can restore a normal heart rhythm in cases of shockable rhythms.

In contrast, the other options listed fail to prioritize the most urgent steps needed to save a life in a cardiac arrest scenario. For instance, checking for a pulse or assessing breathing takes valuable time that could delay interventions that are more critical, like CPR. Additionally, initiating IV access and checking rhythm are important components of post-cardiac arrest care but are not the immediate priorities when someone is in cardiac arrest. Hence, the sequence of calling for help, performing CPR, and using an AED is the most effective and time-sensitive approach during such emergencies
