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

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

Clear role assignment and minimizing interruptions optimize CPR quality in a team setting.

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

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

Encourage the victim to keep coughing instead of immediately intervening.

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

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

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

A firm surface is needed to ensure effective compressions.

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

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

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

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

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

A firm surface is needed to ensure effective compressions.

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

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

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

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

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

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

For adults with a pulse but not breathing, provide 1 breath every 5-6 seconds.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

High-quality CPR requires minimizing interruptions to maintain circulation.

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

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

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

A firm surface is needed to ensure effective compressions.

Encourage the victim to keep coughing instead of immediately intervening.

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

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

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

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