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

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

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

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

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

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

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

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

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

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

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

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

Equal chest rise and fall confirms proper ventilation and airway placement.

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

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.

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

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

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

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.

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.

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

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

Encourage the victim to keep coughing instead of immediately intervening.

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

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

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

Chest compressions keep oxygenated blood circulating to the brain and heart until normal function is restored.

For a choking infant, back slaps and chest thrusts should be used instead of abdominal thrusts.

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

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

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

Encourage the victim to keep coughing instead of immediately intervening.

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

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

A firm surface is needed to ensure effective compressions.

Excessive ventilation can cause complications like gastric inflation.

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

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

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

Each breath should be given over 1 second with just enough volume to see the chest rise.

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

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

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

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

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

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

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

Naloxone should only be administered if opioid overdose is suspected.

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

High-quality CPR requires minimizing interruptions to maintain circulation.

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

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