High-quality CPR requires minimizing interruptions to maintain circulation.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

Encourage the victim to keep coughing instead of immediately intervening.

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

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

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

For adults with a pulse but not breathing, provide 1 breath every 5-6 seconds.

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.

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

A firm surface is needed to ensure effective compressions.

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

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

High-quality CPR requires minimizing interruptions to maintain circulation.

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

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

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

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

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

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

Infant chest compressions should be at least 1/3 of the chest depth, approximately 1.5 inches (4 cm).

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

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

For infants, responsiveness is assessed by tapping the bottom of the foot and shouting.

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

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

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

Effective compressions allow full chest recoil, ensuring proper circulation.

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

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

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

After a shock is delivered, chest compressions should resume immediately to maintain circulation.

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

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.

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

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

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