What is the purpose of the recovery position?✔✔ To maintain an open airway and prevent aspiration in unresponsive, breathing victims.
How do you prioritize care in a multi-victim cardiac arrest scenario?✔✔ Use a triage system, starting CPR on the most salvageable victims first.
What is the key difference between BLS and ACLS?✔✔ BLS focuses on basic life support (CPR, AED), while ACLS includes advanced interventions (medications, intubation).
Why is it important to continue CPR while the AED is charging?✔✔ To minimize interruptions in blood flow to vital organs.
