High-quality CPR requires minimizing interruptions to maintain circulation.

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

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

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

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

Effective compressions allow full chest recoil, ensuring proper circulation.

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

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

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

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

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

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

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

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.

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

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

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

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

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

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

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

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

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

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

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

A firm surface is needed to ensure effective compressions.

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

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

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

Naloxone should only be administered if opioid overdose is suspected.

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

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

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

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.

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

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

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

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

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

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

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

Encourage the victim to keep coughing instead of immediately intervening.

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

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

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

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

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

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

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

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

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

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

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