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

Effective compressions allow full chest recoil, ensuring proper circulation.

Rescuers should switch every 2 minutes (or 5 cycles of compressions) to maintain high-quality CPR.

Excessive ventilation can cause complications like gastric inflation.

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

Encourage the victim to keep coughing instead of immediately intervening.

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

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

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

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

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

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

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

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.

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

Encourage the victim to keep coughing instead of immediately intervening.

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

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

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

High-quality CPR requires minimizing interruptions to maintain circulation.

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

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

The first step is to turn on the AED before attaching pads and following voice prompts.

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

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

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

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

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

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

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

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

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

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

A firm surface is needed to ensure effective compressions.

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

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

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

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

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

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

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

Visible chest rise confirms that breaths are being delivered effectively.

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

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.

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

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

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

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

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

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

Equal chest rise confirms proper ventilation and airway placement.

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

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