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

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

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

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

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

A firm surface is needed to ensure effective compressions.

High-quality chest compressions help circulate oxygenated blood to the brain and heart.

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

Excessive ventilation can cause complications like gastric inflation.

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

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

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

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

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

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

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

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

Gasping (agonal breathing) is not normal breathing and should not delay CPR.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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.

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

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

Encourage the victim to keep coughing instead of immediately intervening.

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

A firm surface is needed to ensure effective compressions.

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

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

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

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

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

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

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

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

High-quality CPR requires minimizing interruptions to maintain circulation.

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

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

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

For suspected spinal injury, the jaw thrust maneuver should be used instead of head tilt-chin lift.

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.

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