High-quality CPR requires minimizing interruptions to maintain circulation.

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

Encourage the victim to keep coughing instead of immediately intervening.

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

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

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

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

Shifting the uterus to the left reduces pressure on the inferior vena cava, improving circulation.

Effective compressions allow full chest recoil, ensuring proper circulation.

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

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

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

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

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

In a hospital setting, bag-mask ventilation is the preferred method for delivering rescue breaths.

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

Over-ventilation can lead to increased intrathoracic pressure, reducing venous return and cardiac output.

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

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

A firm surface is needed to ensure effective compressions.

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

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

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

AED pads should be placed at least 1 inch away from a pacemaker to ensure proper function.

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

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 (or 5 cycles of compressions) to maintain high-quality CPR.

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

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

Equal chest rise confirms proper ventilation and airway placement.

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

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

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

High-quality CPR requires minimizing interruptions to maintain circulation.

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

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

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

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

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

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

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

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

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

Agonal gasps are not normal breathing and should not delay CPR.

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.

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

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

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

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

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

Defibrillation should be performed as soon as a shockable rhythm is detected by the AED.

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

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

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