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

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

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

Equal chest rise confirms proper ventilation and airway placement.

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

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

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

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

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

Encourage the victim to keep coughing instead of immediately intervening.

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

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

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

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

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

Excessive ventilation can cause complications like gastric inflation.

Encourage the victim to keep coughing instead of immediately intervening.

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

High-quality CPR requires minimizing interruptions to maintain circulation.

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

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

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

An AED is used on patients who are unresponsive, pulseless, and not breathing.

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

High-quality CPR requires minimizing interruptions to maintain circulation.

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

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

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

Excessive ventilation can cause complications like gastric inflation.

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

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

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

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

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

Naloxone should only be administered if opioid overdose is suspected.

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

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

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

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

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

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

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

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

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

After a shock is delivered, chest compressions should resume immediately to maintain circulation.

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

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

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

Effective compressions allow full chest recoil, ensuring proper circulation.

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

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

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

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

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

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