If there is any doubt about the presence of a pulse, start chest compressions immediately.

Rescue breathing is recommended for victims with a pulse but inadequate breathing.

The first step after turning on an AED is attaching the electrode pads.

The recommended compression rate is 100-120 compressions per minute.

Rescue breathing is recommended for victims with a pulse but inadequate breathing.

Breathing assessment should take no more than 10 seconds to avoid delaying CPR.

In BLS, medication administration is not a designated role—this falls under ACLS-level care.

Adult chest compressions should be at least 2 inches (5 cm) deep.

Before starting CPR, check for a pulse for no more than 10 seconds to determine if compressions are needed.

Naloxone should only be administered if opioid overdose is suspected.

The recommended compression rate is 100-120 compressions per minute.

Over-ventilation can lead to increased intrathoracic pressure, reducing venous return and cardiac output.

Adult chest compressions should be at least 2 inches (5 cm) deep.

Switching roles every 2 minutes minimizes interruptions and maintains high-quality CPR.

Rescue breathing is the correct response if the patient has a pulse but no breathing.

Excessive ventilation can cause complications like gastric inflation.

If a choking victim becomes unresponsive and pulseless, CPR should begin immediately, starting with compressions.

Rescue breathing is recommended for victims with a pulse but inadequate breathing.

The two-thumb encircling hands technique is the preferred method for two-rescuer infant CPR, as it provides better depth and control.

CPR should continue until the patient shows signs of life, an AED prompts a shock or no shock, or another trained provider takes over.

The two-thumb encircling technique is preferred for two-rescuer infant CPR, while single rescuers typically use two fingers.

For a responsive choking adult, abdominal thrusts (Heimlich maneuver) should be used.

Most AEDs are programmed to reanalyze the heart rhythm every 2 minutes.

Unlike adults, the most common cause of cardiac arrest in infants and children is respiratory failure leading to hypoxia.

High-quality CPR requires minimizing interruptions to maintain circulation.

For a single rescuer, the correct ratio is 30 compressions to 2 breaths.

Rescuers should switch every 2 minutes (or 5 cycles of compressions) to maintain high-quality CPR.

Pediatric AED pads should be used for children under 8 years old, if available.

High-quality chest compressions are the top priority in cardiac arrest, with ventilation as a secondary focus.

If a patient has a pulse but is not breathing adequately, healthcare providers should provide rescue breathing without chest compressions.

Equal chest rise and fall confirms proper ventilation and airway placement.

For infants, responsiveness is assessed by tapping the bottom of the foot and shouting.

Encourage the victim to keep coughing instead of immediately intervening.

For adults with an advanced airway, ventilation should be given at a rate of 1 breath every 6 seconds.

The first step after turning on an AED is attaching the electrode pads.

The best method is to tap the patient and shout to assess for responsiveness.

AED pads should be placed at least 1 inch away from a pacemaker to ensure proper function.

For adult CPR, compressions should be performed with two hands, one on top of the other, placed on the lower half of the sternum.

Switching roles every 2 minutes prevents rescuer fatigue and minimizes interruptions.

For single-rescuer infant CPR, use two fingers just below the nipple line to perform compressions.

Agonal breathing is a sign of cardiac arrest and CPR should be initiated.

Closed-loop communication ensures that orders are acknowledged and carried out correctly.

Chest compressions keep oxygenated blood circulating to the brain and heart until normal function is restored.

For children with a pulse but no normal breathing, provide rescue breaths at a rate of 12-20 per minute.

Chest compressions maintain circulation and deliver oxygenated blood to the brain and heart.

Rescue breaths should be given before starting chest compressions in drowning victims.

The E-C clamp technique ensures a tight seal while lifting the jaw for an open airway.

If the patient has a pulse but is not breathing, rescue breathing should be provided with continuous monitoring.

Rescuers should switch every 2 minutes to maintain high-quality CPR and prevent fatigue.

For a single rescuer, the correct ratio is 30 compressions to 2 breaths.

High-quality CPR for children requires compressing at least 1/3 of the chest depth (about 2 inches or 5 cm).

If a choking victim becomes unresponsive, emergency services should be activated, and CPR should begin immediately.

An AED is used on patients who are unresponsive, pulseless, and not breathing.

For adults with a pulse but not breathing, provide 1 breath every 5-6 seconds.

The first step is to turn on the AED before attaching pads and following voice prompts.
