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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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.

Effective compressions allow full chest recoil, ensuring proper circulation.

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

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

Encourage the victim to keep coughing instead of immediately intervening.

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

A firm surface is needed to ensure effective compressions.

For suspected spinal injury, the jaw thrust maneuver should be used instead of head tilt-chin lift.

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

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

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

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

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

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

Encourage the victim to keep coughing instead of immediately intervening.

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

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

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

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

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

High-quality CPR requires minimizing interruptions to maintain circulation.

Encourage the victim to keep coughing instead of immediately intervening.

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

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

A firm surface is needed to ensure effective compressions.

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

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

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

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

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

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

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

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

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

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

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

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

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

Excessive ventilation can cause complications like gastric inflation.
