A firm surface is needed to ensure effective compressions.

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

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

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

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

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

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

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

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

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

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

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

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

Closed-loop communication ensures that orders are acknowledged and carried out correctly.

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

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

Excessive ventilation can cause complications like gastric inflation.

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

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

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

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

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

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

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

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

Visible chest rise confirms that breaths are being delivered effectively.

Excessive ventilation can cause complications like gastric inflation.

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

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

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

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

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

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

Effective compressions allow full chest recoil, ensuring proper circulation.

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

Encourage the victim to keep coughing instead of immediately intervening.

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

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

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

Reassessment should occur every 5 cycles of CPR (about 2 minutes) unless an AED prompts earlier evaluation.

Switching roles every 2 minutes prevents rescuer fatigue and ensures continuous, high-quality CPR.

Naloxone should only be administered if opioid overdose is suspected.

A firm surface is needed to ensure effective compressions.

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

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

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

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

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.

Equal chest rise confirms proper ventilation and airway placement.

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

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

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

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

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