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

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

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

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

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

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

Naloxone should only be administered if opioid overdose is suspected.

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

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

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

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

Excessive ventilation can cause complications like gastric inflation.

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

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

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

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

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

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

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

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

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

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

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

Rescue breathing is the correct response if the patient has a pulse but no breathing.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

Encourage the victim to keep coughing instead of immediately intervening.

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

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

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

For a choking infant, back slaps and chest thrusts should be used instead of abdominal thrusts.

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

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

For children, compress the chest at least 1/3 of its diameter (about 2 inches or 5 cm).

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

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

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

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

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

Equal chest rise confirms proper ventilation and airway placement.

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