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

A bag-mask device (BVM) is preferred for healthcare providers as it delivers more effective ventilations.

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

Encourage the victim to keep coughing instead of immediately intervening.

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

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

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

Excessive ventilation can cause complications like gastric inflation.

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.

Encourage the victim to keep coughing instead of immediately intervening.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

Reassessment should occur every 5 cycles of CPR (about 2 minutes) unless an AED prompts earlier evaluation.

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

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

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

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

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

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

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

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

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

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.

If a patient has a pulse but is not breathing adequately, healthcare providers should provide rescue breathing without chest compressions.

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.

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

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

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

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

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

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

For children, compress the chest at least 1/3 of its diameter (about 2 inches or 5 cm).

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

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

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