Equal chest rise confirms proper ventilation and airway placement.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

To minimize interruptions in care, breathing and pulse checks should be performed simultaneously, taking no more than 10 seconds.

A firm surface is needed to ensure effective compressions.

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

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

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

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

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

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

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

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

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

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

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

In BLS, medication administration is not a designated role—this falls under ACLS-level care.

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

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

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

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

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

Encourage the victim to keep coughing instead of immediately intervening.

A firm surface is needed to ensure effective compressions.

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

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

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

A firm surface is needed to ensure effective compressions.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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