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

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

High-quality CPR requires minimizing interruptions to maintain circulation.

A firm surface is needed to ensure effective compressions.

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

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

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

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

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

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

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

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

Encourage the victim to keep coughing instead of immediately intervening.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

AED pads should be placed at least 1 inch away from a pacemaker to ensure proper function.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

When a shockable rhythm is detected, defibrillation should be performed as soon as possible.

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