Encourage the victim to keep coughing instead of immediately intervening.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

High-quality CPR for children requires compressing at least 1/3 of the chest depth (about 2 inches or 5 cm).

A firm surface is needed to ensure effective compressions.

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

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

Once an advanced airway is in place, continuous compressions should be given at 100-120 per minute without pausing for breaths.

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.

Excessive ventilation can cause complications like gastric inflation.

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

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

Visible chest rise confirms that breaths are being delivered effectively.

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

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

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

Excessive ventilation can cause complications like gastric inflation.

Excessive ventilation can cause complications like gastric inflation.

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

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

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

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

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

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

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.

AED pads should be placed at least 1 inch away from a pacemaker to avoid interference.

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

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

High-quality CPR requires minimizing interruptions to maintain circulation.

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

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

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

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.

If the AED does not advise a shock, rescuers should immediately resume CPR.

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

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

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