Chapter 14- BLS Resucitation

Question 1

The combination of chest compressions and rescue breathing used to establish adequate berating and circulation in a patient who is not breathing and has no pulse.

Answer 1

cardiopulmonary resuscitation

Question 2

The exchange of air between the lungs and the environment; occurs spontaneously by the patient or with assistance from another person, such as an EMT.

Answer 2

ventilation

Question 3

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

Answer 3

return of spontaneous circulation

Question 4

The preferred method to dislodge a severe airway obstruction in adults and children; also called the Heimlich maneuver.

Answer 4

abdominal thrust maneuver

Question 5

Advanced life-saving procedures, some of which are now being provided by the EMT.

Answer 5

advanced life support

Question 6

The total percentage of time during a resuscitation attempt in which active chest compressions are being performed.

Answer 6

chest compression fraction

Question 7

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

Answer 7

gastric distention

Question 8

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

Answer 8

load-distributing band

Question 9

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

Answer 9

mechanical piston device

Question 10

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.

Answer 10

recovery position

Question 11

Technique to open the airway by placing the fingers behind the angle of the jaw AB’s bringing the jaw forward; used for patients who may have a cervical spine injury.

Answer 11

jaw-thrust maneuver

Question 12

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

Answer 12

rigor mortis

Question 13

A valve device placed between the endotracheal tube and a bag-mask device that limits the amount of air entering the lungs during the recoil phase between chest compressions.

Answer 13

impedance threshold device

Question 14

A combination of two movements to open the airway by tilting the forehead back and lifting the chin; not used for trauma patients.

Answer 14

head tilt-chin lift maneuver

Question 15

A harsh, high-pitched respiratory sound, generally heard during inspiration, that is caused by partial blockage and narrowing of the upper airway; may be audible without a stethoscope.

Answer 15

stridor

Question 16

A lack of oxygen that deprives tissues of necessary nutrients, resulting from partial or complete blockage of blood flow; potentially reversible because permanent injury has not yet occurred.

Answer 16

ischemia

Question 17

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

Answer 17

basic life support

Question 18

A technique that involves compressing the chest and then actively pulling it back up to its neutral position or beyond (decompression); may increase the amount of blood ejected from the heart during the compression phase.

Answer 18

active compression-decompression CPR

Question 19

Rapid or deep breathing that lowers the blood carbon dioxide level below normal; may lead to increased intrathoracic pressure, decreased venous return, and hypotension when associated with bad-mask device use.

Answer 19

hyperventilation

Question 20

Blood settling to the lowest point of the body, causing discoloration of the skin; a definitive sign of death.

Answer 20

dependent lividity
