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

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

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

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

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

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

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

A firm surface is needed to ensure effective compressions.

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

For an unresponsive, pulseless patient, immediate chest compressions are the priority.

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

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.

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

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

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

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

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

Visible chest rise confirms that breaths are being delivered effectively.

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

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 should be initiated for a patient with a pulse but no normal breathing.

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

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

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

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

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

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

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

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

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

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

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

Encourage the victim to keep coughing instead of immediately intervening.

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

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

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

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

Excessive ventilation can cause complications like gastric inflation.

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

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

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

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

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.

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

Chest compressions should continue while the AED is charging to maintain circulation.

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

High-quality CPR requires minimizing interruptions to maintain circulation.

A firm surface is needed to ensure effective compressions.

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

Effective compressions allow full chest recoil, ensuring proper circulation.

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

Excessive ventilation can cause complications like gastric inflation.
