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

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

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

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

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

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

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

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

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

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

Effective compressions allow full chest recoil, ensuring proper circulation.

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

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

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

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

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

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

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

Visible chest rise confirms that breaths are being delivered effectively.

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

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

Excessive ventilation can cause complications like gastric inflation.

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

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

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

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

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

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

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

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

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

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

Naloxone should only be administered if opioid overdose is suspected.

An AED is used on patients who are unresponsive, pulseless, and not breathing.

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

The first step is to turn on the AED before attaching pads and following voice prompts.

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

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

A firm surface is needed to ensure effective compressions.

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

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

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

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

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

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

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.

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

Encourage the victim to keep coughing instead of immediately intervening.

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

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

A firm surface is needed to ensure effective compressions.

Encourage the victim to keep coughing instead of immediately intervening.

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

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