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

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

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

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

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

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

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

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

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

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

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

Agonal gasps are not normal breathing and should not delay CPR.

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

Naloxone should only be administered if opioid overdose is suspected.

A firm surface is needed to ensure effective compressions.

Encourage the victim to keep coughing instead of immediately intervening.

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

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

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

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

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

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

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

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

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

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

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

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

A firm surface is needed to ensure effective compressions.

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

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

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

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

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

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

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

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

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

If a choking victim becomes unresponsive, emergency services should be activated, and CPR should begin immediately.

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

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

Chest compressions keep oxygenated blood circulating to the brain and heart until normal function is restored.

Switching roles every 2 minutes minimizes interruptions and maintains high-quality CPR.

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

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

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

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

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

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

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

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

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

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

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

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