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

Encourage the victim to keep coughing instead of immediately intervening.

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

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

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

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

Excessive ventilation can cause complications like gastric inflation.

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

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

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

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

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

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

Excessive ventilation can cause complications like gastric inflation.

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

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

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

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

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

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

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

Effective compressions allow full chest recoil, ensuring proper circulation.

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

Equal chest rise confirms proper ventilation and airway placement.

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

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

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

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

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

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

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

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

An AED analyzes the heart rhythm and delivers a shock if a shockable rhythm is present.

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

High-quality CPR requires minimizing interruptions to maintain circulation.

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

High-quality CPR requires minimizing interruptions to maintain circulation.

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

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

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

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

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

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

Encourage the victim to keep coughing instead of immediately intervening.

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

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

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

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.

Encourage the victim to keep coughing instead of immediately intervening.

Each breath should be given over 1 second with just enough volume to see the chest rise.

The first step is to turn on the AED before attaching pads and following voice prompts.

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

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

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