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

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

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

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

Visible chest rise confirms that breaths are being delivered effectively.

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

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

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

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

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

Encourage the victim to keep coughing instead of immediately intervening.

Equal chest rise confirms proper ventilation and airway placement.

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

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

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

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

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

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

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

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

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

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

If the AED does not advise a shock, rescuers should immediately resume CPR.

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

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

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

A firm surface is needed to ensure effective compressions.

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

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

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

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

Single-rescuer infant CPR follows the 30:2 compression-to-ventilation ratio, just like adults.

High-quality CPR requires minimizing interruptions to maintain circulation.

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

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

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

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

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

A firm surface is needed to ensure effective compressions.

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

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

Early defibrillation is the most critical step in increasing survival rates for patients in cardiac arrest with a shockable rhythm.

For suspected spinal injuries, the jaw thrust maneuver is used instead of head tilt-chin lift to maintain spinal alignment.

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

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

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

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

In a hospital setting, bag-mask ventilation is the preferred method for delivering rescue breaths.

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

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

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

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

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

For a choking infant, back slaps and chest thrusts should be used instead of abdominal thrusts.

Agonal gasps are not normal breathing and should not delay CPR.
