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

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

High-quality CPR requires minimizing interruptions to maintain circulation.

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

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

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

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

Visible chest rise confirms that breaths are being delivered effectively.

A firm surface is needed to ensure effective compressions.

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

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

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

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

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

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

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

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

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

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

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

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

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

Encourage the victim to keep coughing instead of immediately intervening.

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

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

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

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

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

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

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

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

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

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

High-quality CPR requires minimizing interruptions to maintain circulation.

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

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

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

Encourage the victim to keep coughing instead of immediately intervening.

Equal chest rise confirms proper ventilation and airway placement.

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

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

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

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

Effective compressions allow full chest recoil, ensuring proper circulation.

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

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

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

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.

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

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

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

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

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