Excessive ventilation can cause complications like gastric inflation.

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

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

Encourage the victim to keep coughing instead of immediately intervening.

A firm surface is needed to ensure effective compressions.

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

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

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

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

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

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

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

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

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

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

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

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

High-quality CPR requires minimizing interruptions to maintain circulation.

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

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

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

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

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

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

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

High-quality CPR requires minimizing interruptions to maintain circulation.

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

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

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

Effective compressions allow full chest recoil, ensuring proper circulation.

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

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

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

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

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

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

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

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

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

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

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

Naloxone should only be administered if opioid overdose is suspected.

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

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

Before starting CPR, check for a pulse for no more than 10 seconds to determine if compressions are needed.

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

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

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

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

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

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

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

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

A firm surface is needed to ensure effective compressions.

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