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

Excessive ventilation can cause complications like gastric inflation.

Over-ventilation can lead to increased 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.

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

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

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

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

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

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

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

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

For children, compress the chest at least 1/3 of its diameter (about 2 inches or 5 cm).

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

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

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

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

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

Encourage the victim to keep coughing instead of immediately intervening.

High-quality CPR requires minimizing interruptions to maintain circulation.

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

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.

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

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

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

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

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

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

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

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

High-quality CPR requires minimizing interruptions to maintain circulation.

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

A firm surface is needed to ensure effective compressions.

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

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

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

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

Visible chest rise confirms that breaths are being delivered effectively.

Encourage the victim to keep coughing instead of immediately intervening.

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

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

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

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

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

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

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

Excessive ventilation can cause complications like gastric inflation.

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

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

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

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

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

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

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