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

Excessive ventilation can cause complications like gastric inflation.

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

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

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

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

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

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

Excessive ventilation can cause complications like gastric inflation.

If a patient has a pulse but is not breathing adequately, healthcare providers should provide rescue breathing without chest compressions.

Effective compressions allow full chest recoil, ensuring proper circulation.

A firm surface is needed to ensure effective compressions.

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

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

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

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

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

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

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

A firm surface is needed to ensure effective compressions.

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

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

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

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

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

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

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

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

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

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

Equal chest rise confirms proper ventilation and airway placement.

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

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

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

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

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

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

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

Visible chest rise confirms that breaths are being delivered effectively.

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

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

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

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

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

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

Gasping (agonal breathing) is not normal breathing and should not delay CPR.

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

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

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

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

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

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

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

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

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