Single-rescuer infant CPR follows the 30:2 compression-to-ventilation ratio, just like adults.

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

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

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

Naloxone should only be administered if opioid overdose is suspected.

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

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

Visible chest rise confirms that breaths are being delivered effectively.

Encourage the victim to keep coughing instead of immediately intervening.

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

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

Once an advanced airway is in place, continuous compressions should be given at 100-120 per minute without pausing for breaths.

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

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

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

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

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

High-quality chest compressions are the top priority in cardiac arrest, with ventilation as a secondary focus.

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

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

Equal chest rise confirms proper ventilation and airway placement.

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

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

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

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

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

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

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

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

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

The E-C clamp technique ensures a tight seal while lifting the jaw for an open airway.

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

Encourage the victim to keep coughing instead of immediately intervening.

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

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

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

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

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

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

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

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

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

A firm surface is needed to ensure effective compressions.

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

The two-thumb encircling hands technique is the preferred method for two-rescuer infant CPR, as it provides better depth and control.

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

Excessive ventilation can cause complications like gastric inflation.

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

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

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

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

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

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

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

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