When a shockable rhythm is detected, defibrillation should be performed as soon as possible.

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

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

Rescue breathing should be initiated for a patient with a pulse but no normal breathing.

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

Breaths should be delivered over 1 second each to produce visible chest rise.

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

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

For an unresponsive, pulseless patient, immediate chest compressions are the priority.

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

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

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

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

High-quality CPR requires minimizing interruptions to maintain circulation.

After a shock is delivered, chest compressions should resume immediately to maintain circulation.

Gasping (agonal breathing) is not normal breathing and should not delay CPR.

Encourage the victim to keep coughing instead of immediately intervening.

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

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

Naloxone should only be administered if opioid overdose is suspected.

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

Effective compressions allow full chest recoil, ensuring proper circulation.

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

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

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

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

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

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

The carotid artery is the preferred site for pulse assessment in unresponsive adults.

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

Each breath should be given over 1 second with just enough volume to see the chest rise.

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

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

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

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

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

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

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

For children, compress the chest at least 1/3 of its diameter (about 2 inches or 5 cm).

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

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

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

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

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

The correct compression depth for adult CPR is at least 2 inches (5 cm).

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

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

Switching roles every 2 minutes ensures high-quality compressions without fatigue.

High-quality CPR requires minimizing interruptions to maintain circulation.

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

High-quality CPR requires minimizing interruptions to maintain circulation.

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

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

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

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