The two-thumb encircling technique is preferred for two-rescuer infant CPR, while single rescuers typically use two fingers.

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.

Effective compressions allow full chest recoil, ensuring proper circulation.

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

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

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

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.

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

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

High-quality CPR requires minimizing interruptions to maintain circulation.

High-quality CPR requires minimizing interruptions to maintain circulation.

Encourage the victim to keep coughing instead of immediately intervening.

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

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

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

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

Visible chest rise confirms that breaths are being delivered effectively.

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

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

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

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

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

Excessive ventilation can cause complications like gastric inflation.

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

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

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

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

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

Equal chest rise confirms proper ventilation and airway placement.

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

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

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

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

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

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

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

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

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

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

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

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

Breathing assessment should take no more than 10 seconds to avoid delaying CPR.

A firm surface is needed to ensure effective compressions.

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

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

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

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

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

For single-rescuer infant CPR, use two fingers just below the nipple line to perform compressions.

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

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

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