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

Effective compressions allow full chest recoil, ensuring proper circulation.

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

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

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

High-quality CPR requires minimizing interruptions to maintain circulation.

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

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

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

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

Naloxone should only be administered if opioid overdose is suspected.

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

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

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

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

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

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

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

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

Encourage the victim to keep coughing instead of immediately intervening.

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

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

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

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

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

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

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

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

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

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.

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

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

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

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

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

Encourage the victim to keep coughing instead of immediately intervening.

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

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

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

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

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

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

For children with a pulse but no normal breathing, provide rescue breaths at a rate of 12-20 per minute.

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

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

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

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

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

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

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

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

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

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