Healthcare BLS Provider Certification Course

High-quality CPR requires minimizing interruptions to maintain circulation.

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

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

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

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

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

Excessive ventilation can cause complications like gastric inflation.

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

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

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

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

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

Equal chest rise and fall confirms proper ventilation and airway placement.

The E-C clamp technique ensures a tight seal while lifting the jaw for an open airway.

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

High-quality CPR requires minimizing interruptions to maintain circulation.

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

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

Excessive ventilation can cause complications like gastric inflation.

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

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

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

Encourage the victim to keep coughing instead of immediately intervening.

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

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

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

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

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

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.

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

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

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

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

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

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

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

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

A firm surface is needed to ensure effective compressions.

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

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

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

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

A firm surface is needed to ensure effective compressions.

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

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

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

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

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

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

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

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

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

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.
