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

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

A firm surface is needed to ensure effective compressions.

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

Equal chest rise confirms proper ventilation and airway placement.

Once an advanced airway is in place, continuous compressions should be given at 100-120 per minute without pausing for breaths.

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

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

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

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

Encourage the victim to keep coughing instead of immediately intervening.

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

A firm surface is needed to ensure effective compressions.

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

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

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

Effective compressions allow full chest recoil, ensuring proper circulation.

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

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

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

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

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

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

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

Excessive ventilation can cause complications like gastric inflation.

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

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

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

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

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

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

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.

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

Excessive ventilation can cause complications like gastric inflation.

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.

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

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

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

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

Excessive ventilation can cause complications like gastric inflation.

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

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.

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

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

Naloxone should only be administered if opioid overdose is suspected.

High-quality CPR requires minimizing interruptions to maintain circulation.

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

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

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.

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

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