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

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

Encourage the victim to keep coughing instead of immediately intervening.

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

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

Breaths should be delivered over 1 second each to produce visible chest rise.

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

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

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

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

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

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

Excessive ventilation can cause complications like gastric inflation.

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

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

Encourage the victim to keep coughing instead of immediately intervening.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

High-quality CPR requires minimizing interruptions to maintain circulation.

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

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

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

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

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.

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

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

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

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

A firm surface is needed to ensure effective compressions.

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

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

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

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

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

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

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

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