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

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

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

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

Visible chest rise confirms that breaths are being delivered effectively.

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

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

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.

A firm surface is needed to ensure effective compressions.

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

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

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

High-quality CPR requires minimizing interruptions to maintain circulation.

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

Equal chest rise confirms proper ventilation and airway placement.

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

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

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

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

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

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

Excessive ventilation can cause complications like gastric inflation.

Unless a valid DNR order is confirmed, resuscitation efforts should begin.

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

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

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

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

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

Encourage the victim to keep coughing instead of immediately intervening.

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

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

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

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

Encourage the victim to keep coughing instead of immediately intervening.

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

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

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

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

In BLS, medication administration is not a designated role—this falls under ACLS-level care.

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

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

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

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

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

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

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

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

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

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

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

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

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.

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