Clear role assignment and minimizing interruptions optimize CPR quality in a team setting.

Unless a valid DNR order is confirmed, resuscitation efforts should begin.

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

A firm surface is needed to ensure effective compressions.

Infant chest compressions should be at least 1/3 of the chest depth, approximately 1.5 inches (4 cm).

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

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

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

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

Equal chest rise confirms proper ventilation and airway placement.

Shifting the uterus to the left reduces pressure on the inferior vena cava, improving circulation.

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

Switching roles every 2 minutes prevents rescuer fatigue and ensures continuous, high-quality CPR.

Ventilations should be given every 6 seconds when an advanced airway is in place.

Defibrillation should be performed as soon as a shockable rhythm is detected by the AED.

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

High-quality CPR for adults requires compressions at least 2 inches deep at a rate of 100-120 per minute.

Encourage the victim to keep coughing instead of immediately intervening.

If a choking victim can cough or speak, encourage them to keep coughing rather than immediately performing abdominal thrusts.

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

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

Excessive ventilation can cause complications like gastric inflation.

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

For two-rescuer infant CPR, the correct ratio is 15:2, not 30:2.

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

A bag-mask device (BVM) is preferred for healthcare providers as it delivers more effective ventilations.

For infants, the correct pulse check location is the brachial artery (inside the upper arm).

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

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

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

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

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

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

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

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

High-quality CPR requires minimizing interruptions to maintain circulation.

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

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

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

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

Excessive ventilation can cause complications like gastric inflation.

Once an advanced airway is in place, continuous compressions are given with 1 breath every 6 seconds.

An AED analyzes the heart rhythm and delivers a shock if a shockable rhythm is present.

Visible chest rise confirms that breaths are being delivered effectively.

Pulse checks should be performed approximately every 2 minutes when providing rescue breathing.

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

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

For two-rescuer infant CPR, the correct compression-to-ventilation ratio is 15:2.

AED pads should be placed at least 1 inch away from a pacemaker to avoid interference.

Pulse checks should be limited to 10 seconds to avoid delaying CPR.

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

To minimize interruptions in care, breathing and pulse checks should be performed simultaneously, taking no more than 10 seconds.

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

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

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