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

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

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

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

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

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

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

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

Visible chest rise confirms that breaths are being delivered effectively.

High-quality CPR requires minimizing interruptions to maintain circulation.

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

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

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

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

A firm surface is needed to ensure effective compressions.

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

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

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

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

Encourage the victim to keep coughing instead of immediately intervening.

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

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

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

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

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

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

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

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

A firm surface is needed to ensure effective compressions.

Rescuers should switch every 2 minutes to maintain high-quality CPR and prevent fatigue.

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

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.

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

CPR should continue until the patient shows signs of life, an AED prompts a shock or no shock, or another trained provider takes over.

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

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

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

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

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

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

Effective compressions allow full chest recoil, ensuring proper circulation.

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

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

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

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

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

The carotid artery is the preferred site for pulse assessment in unresponsive adults.

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

Equal chest rise confirms proper ventilation and airway placement.

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

Encourage the victim to keep coughing instead of immediately intervening.

High-quality CPR requires minimizing interruptions to maintain circulation.

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

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