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

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

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

A firm surface is needed to ensure effective compressions.

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

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

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

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

Encourage the victim to keep coughing instead of immediately intervening.

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

Encourage the victim to keep coughing instead of immediately intervening.

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

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

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

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

Equal chest rise confirms proper ventilation and airway placement.

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

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

Encourage the victim to keep coughing instead of immediately intervening.

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

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

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

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

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

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

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

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

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

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

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

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

Visible chest rise confirms that breaths are being delivered effectively.

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

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

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

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

Effective compressions allow full chest recoil, ensuring proper circulation.

Naloxone should only be administered if opioid overdose is suspected.

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

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

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

High-quality CPR requires minimizing interruptions to maintain circulation.

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

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

If a patient is unresponsive with a suspected airway obstruction, chest compressions should be initiated immediately to help clear the airway.

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

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

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

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

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.

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.

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

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