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

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

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

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

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

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

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

Excessive ventilation can cause complications like gastric inflation.

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

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

Excessive ventilation can cause complications like gastric inflation.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

Unlike adults, the most common cause of cardiac arrest in infants and children is respiratory failure leading to hypoxia.

High-quality CPR requires minimizing interruptions to maintain circulation.

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

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

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

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

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

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

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

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

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

Naloxone should only be administered if opioid overdose is suspected.

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

High-quality CPR requires minimizing interruptions to maintain circulation.

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

Excessive ventilation can cause complications like gastric inflation.

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

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

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

Visible chest rise confirms that breaths are being delivered effectively.

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

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

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

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

Encourage the victim to keep coughing instead of immediately intervening.

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

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

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

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