For adult CPR, compressions should be performed with two hands, one on top of the other, placed on the lower half of the sternum.

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

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

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

Encourage the victim to keep coughing instead of immediately intervening.

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

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

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

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

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

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

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

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

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

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

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

Excessive ventilation can cause complications like gastric inflation.

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

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

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

High-quality CPR requires minimizing interruptions to maintain circulation.

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

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

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

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

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

Switching roles every 2 minutes minimizes interruptions and maintains high-quality CPR.

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

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.

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

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

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

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

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

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

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

Chest compressions maintain circulation and deliver oxygenated blood to the brain and heart.

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

Naloxone should only be administered if opioid overdose is suspected.

Encourage the victim to keep coughing instead of immediately intervening.

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.

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

Encourage the victim to keep coughing instead of immediately intervening.

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

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

Excessive ventilation can cause complications like gastric inflation.

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

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

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

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

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

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

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