Healthcare BLS Provider Certification Course

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

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

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

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

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

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

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

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

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

A firm surface is needed to ensure effective compressions.

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

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

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

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

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

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

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

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

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

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

High-quality CPR requires minimizing interruptions to maintain circulation.

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.

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

Encourage the victim to keep coughing instead of immediately intervening.

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

Naloxone should only be administered if opioid overdose is suspected.

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

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

Excessive ventilation can cause complications like gastric inflation.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

Switching roles every 2 minutes prevents rescuer fatigue and ensures continuous, high-quality CPR.

Visible chest rise confirms that breaths are being delivered effectively.

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

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

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.

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

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

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

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