High-quality CPR requires minimizing interruptions to maintain circulation.

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

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

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

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

Excessive ventilation can cause complications like gastric inflation.

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

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

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

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

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

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

High-quality CPR requires minimizing interruptions to maintain circulation.

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

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

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

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

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

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

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

High-quality CPR for adults requires compressions at least 2 inches deep at a rate of 100-120 per minute.

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

Gasping (agonal breathing) is not normal breathing and should not delay CPR.

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

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

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

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

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.

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

Pediatric AED pads should be used for children under 8 years old, if available.

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

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

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

Visible chest rise confirms that breaths are being delivered effectively.

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

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

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

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

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

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

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

For a responsive choking adult, abdominal thrusts (Heimlich maneuver) should be used.

Encourage the victim to keep coughing instead of immediately intervening.

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

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

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

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

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

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

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

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

Excessive ventilation can cause complications like gastric inflation.

Effective compressions allow full chest recoil, ensuring proper circulation.

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