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

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

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

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

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

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

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

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

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

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

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

Equal chest rise confirms proper ventilation and airway placement.

Encourage the victim to keep coughing instead of immediately intervening.

Naloxone should only be administered if opioid overdose is suspected.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

Visible chest rise confirms that breaths are being delivered effectively.

Effective compressions allow full chest recoil, ensuring proper circulation.

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

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

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

A firm surface is needed to ensure effective compressions.

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

If a choking victim becomes unresponsive, emergency services should be activated, and CPR should begin immediately.

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

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

For adult CPR, compressions should be performed with two hands, one on top of the other, placed on the lower half of the sternum.

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

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

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

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

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

A firm surface is needed to ensure effective compressions.

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

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