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

Effective compressions allow full chest recoil, ensuring proper circulation.

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

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

For infants, the correct pulse check location is the brachial artery (inside the upper arm).

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

A firm surface is needed to ensure effective compressions.

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

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

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

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

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.

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

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

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

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

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

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

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

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

Naloxone should only be administered if opioid overdose is suspected.

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

High-quality CPR requires minimizing interruptions to maintain circulation.

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

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

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

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

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

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.

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

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

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

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

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

AED pads should be placed at least 1 inch away from a pacemaker to avoid interference.

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

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

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

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

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

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

A firm surface is needed to ensure effective compressions.

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

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

For infants, responsiveness is assessed by tapping the bottom of the foot and shouting.

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.

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

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

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

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

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