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

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

Equal chest rise confirms proper ventilation and airway placement.

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

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

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

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

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

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

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

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

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

Visible chest rise confirms that breaths are being delivered effectively.

Over-ventilation can increase intrathoracic pressure, reducing venous return and cardiac output.

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

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

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

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

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

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

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

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

Encourage the victim to keep coughing instead of immediately intervening.

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

Excessive ventilation can cause complications like gastric inflation.

High-quality CPR requires minimizing interruptions to maintain circulation.

Visible chest rise is the best indicator that rescue breaths are effectively ventilating the lungs.

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

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

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

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

If a patient is unresponsive with a suspected airway obstruction, chest compressions should be initiated immediately to help clear the airway.

High-quality chest compressions help circulate oxygenated blood to the brain and heart.

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

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

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

A firm surface is needed to ensure effective compressions.

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

The best way to ensure effective ventilation is by observing visible chest rise with each breath.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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