A firm surface is needed to ensure effective compressions.

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

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

Excessive ventilation can cause complications like gastric inflation.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

Once an advanced airway is in place, continuous compressions should be given at 100-120 per minute without pausing for breaths.

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

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

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

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

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

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

High-quality CPR requires minimizing interruptions to maintain circulation.

Naloxone should only be administered if opioid overdose is suspected.

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

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

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

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

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

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

Rescue breathing should be initiated for a patient with a pulse but no normal breathing.

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

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

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

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

High-quality CPR requires minimizing interruptions to maintain circulation.

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

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

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

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

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

For suspected spinal injuries, the jaw thrust maneuver is used instead of head tilt-chin lift to maintain spinal alignment.

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

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

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

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

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

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

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