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

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

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

Excessive ventilation can cause complications like gastric inflation.

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

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

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

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

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

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

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

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

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

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

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

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

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

Excessive ventilation can cause complications like gastric inflation.

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

Encourage the victim to keep coughing instead of immediately intervening.

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

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

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

Naloxone should only be administered if opioid overdose is suspected.

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

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

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

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

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

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

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

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

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

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

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

Closed-loop communication ensures that orders are acknowledged and carried out correctly.

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

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

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

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

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

For adult CPR, compressions should be performed with two hands, one on top of the other, placed on the lower half of the sternum.

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

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

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

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

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

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

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

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

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

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

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

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

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