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

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

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

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

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

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

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

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.

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

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

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

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

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

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.

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

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

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

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

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

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

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

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

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

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

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

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

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

Naloxone should only be administered if opioid overdose is suspected.

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

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

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

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

Excessive ventilation can cause complications like gastric inflation.

A firm surface is needed to ensure effective compressions.

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

Effective compressions allow full chest recoil, ensuring proper circulation.

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

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.

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

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

High-quality CPR requires minimizing interruptions to maintain circulation.

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

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

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

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

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

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

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

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.

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

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