Final answer:
The ACLS algorithm for PEA/Asystole emphasizes the sequence of circulation, airway, and breathing (CAB). It involves initiating high-quality chest compressions, opening the airway, providing rescue breaths, using an AED if available, and following ACLS medication protocols.
Step-by-step explanation:
The correct response for the Advanced Cardiovascular Life Support (ACLS) algorithm for pulseless electrical activity (PEA) arrest or asystole is circulation, airway, breathing (CAB). This sequence emphasizes the importance of chest compressions over rescue breaths in cardiac arrest scenarios. Here's a brief outline of the steps:
Confirm cardiac arrest: Check for responsiveness and absence of normal breathing. If no pulse is present and the patient is not breathing normally, initiate CPR.
Activate the emergency response system: Call for help and get the automated external defibrillator (AED) if one is available.Chest compressions: Start with high-quality chest compressions at a rate of 100-120 per minute and a depth of at least 5 cm.Airway: Open the airway using a head-tilt-chin-lift maneuver.Breathing: Provide rescue breaths, either with a bag-mask device or advanced airway, at a ratio of 30 compressions to 2 breaths.Assess rhythm and administer medications: Use an AED as soon as available, and follow ACLS protocols for medication administration.Continue resuscitation efforts: Continue CPR until advanced life support providers take over or the patient exhibits signs of life.
For asystole, do not defibrillate; continue with chest compressions and follow ACLS protocols for possible causes and appropriate medications. For PEA, continue with high-quality CPR, and treat any reversible causes.
