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

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.

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

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

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

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

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

Effective compressions allow full chest recoil, ensuring proper circulation.

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

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

If the patient has a pulse but is not breathing, rescue breathing should be provided with continuous monitoring.

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

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

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

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

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

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

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

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.

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

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

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

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

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

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

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

Shifting the uterus to the left reduces pressure on the inferior vena cava, improving circulation.

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

Excessive ventilation can cause complications like gastric inflation.

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

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

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

High-quality CPR requires minimizing interruptions to maintain circulation.

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

Visible chest rise is the best indicator that rescue breaths are effectively ventilating the lungs.

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

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

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

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

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

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

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

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

Encourage the victim to keep coughing instead of immediately intervening.

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

Rescuers should switch every 2 minutes to maintain high-quality CPR and prevent fatigue.

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

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

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

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

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

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

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