100

This is used to re-establish circulation and artificial ventilation i a patient who is not breathing and has no pulse.

What is Cardiopulmonary Resuscitation (CPR)

100

This is step 3 in the links of the chain of survival and it offers the best opportunity to achieve a successful patient outcome.

What is rapid defibrillation?

100

In two-rescuer CPR this is the compression to breaths ratio in an adult.

What is 30:2

100

A technique that involves compressing the chest and then actively pulling it back up to its neutral position or beyond.

What is active compression-decompression CPR?

100

The total percentage of time during a high-quality CPR resuscitation attempt in which chest compressions are being performed.

What is Chest Compression Fraction?

200

The noninvasive emergency life-saving care that is used to treat medical conditions, including airway obstruction, respiratory arrest, and cardiac arrest.

What is Basic Life Support (BLS)

200

This step is physical and emotional and can take a year or longer for people who are eventually resuscitated.

What is step 6, Recovery?

200

This is the rate of compressions for CPR in an adults.

What is 100-120?

200

A device that depresses the sternum via a compressed gas-powered or electric-powered plunger mounted on a backboard.

What is a mechanical piston device?

200
A side-lying position used to maintain a clear airway in unresponsive patients who are breathing adequately and do not have suspected injuries to the spine, hips, or pelvis.

What is the recovery position?

300

If the brain is deprived of oxygen for this range of time, brain damage is possible.

What is 4-6 minutes?

300

In step 2 this will keep blood and therefor oxygen, flowing to the vital organs to keep the patient alive until the other components of the chain are available.

What is CPR?

300

In two-rescuer CPR, the compressor and the ventilator should switch positions this often.

What is 2 minutes?

300

A mechanical pump that is implanted in the chest and helps pump blood from the left ventricle to the aorta. It must have an external power source that is typically worn on the pt's belt or over the shoulder harness.

What is an LVAD?

300

The return of a pulse and effective blood flow to the body in a patient who previously was in cardiac arrest.

What is ROSC?


400

This involves advanced life-saving procedures such as cardiac monitoring, administration of IV fluids and medications, and the use of advanced airway adjuncts.

What is Advanced Life Support (ALS)?

400

Recognition and activation of the emergency response system is this step in the links of the chain of survival.

What is step 1?

400

In one-rescuer CPR this is the compression to breaths ratio in an adult.

What is 30:2

400

A circumferential chest compression device composed of a constricting band and backboard. It is either electronically or pneumatically driven to compress the heart by putting inward pressure on the thorax.

What is a load-distributing band(LBD)?

400

Stiffening of the body muscles; a definitive sign of death.

What is rigor mortis?

500

High quality these with minimal interruptions and early defibrillation have been proven to be independent predictors of successful resuscitation from cardiac arrest and survival to hospital discharge.

What are chest compressions?

500

The 5th step in the link of the chain of survival.

What is Advanced life support and postarrest care?

500

It should take no longer than this for compressor and ventilator to switch positions.

What is 10 seconds?

500

A valve device placed between the ET tube and a bag-mask device and it's designed to limit the amount of air entering the lungs during the recoil phase between chest compressions.

What is an impedance threshold device (ITD)?

500

A condition in which air fills the stomach, often as a result of high volume and pressure during artificial ventilation.

What is gastric distention?
