1
Q

Abdominal-thrust maneuver

A

Also called Heinrich maneuver, preferred method to dislodge a severe airway obstruction in adults and children

2
Q

Chest compression fraction

A

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

3
Q

Dependent lividity

A

Look settling to the lower point of the body, causing discoloration of the skin; a definitive sign of death

4
Q

Gastric distention

A

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

5
Q

Hyperventilation

A

Rapid or deep breathing that lowers the blood carbon dioxide level below normal.

6
Q

Impedance threshold device (ITD)

A

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

7
Q

Ischemia

A

A lack of oxygen that deprives tissues of necessary nutrients, resulting from partial or complete blockage of blood flow

8
Q

Load-distributing band (LDB)

A

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.

9
Q

Mechanical piston device

A

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

10
Q

Recovery position

A

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

11
Q

Rigor Morris

A

Stiffening of the body muscles; a definitive sign of death

12
Q

Stridor

A

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

13
Q

Ventilation

A

Exchange of air between the lungs and the environment

14
Q

Compression rate on infants, children, and adults

A

100-120 Beats a minute

15
Q

Compression depth for children and infants

A

Children- 2 inches and 5 centimeters

Infants- 1.5 inches

16
Q

Compression area in children and infants

A

Children- in the center of the chest, in between the nipples

Infants- just below the nipple line

17
Q

Pulse check for infants and children

A

Children- carotid or femoral

Infants- brachial

18
Q

Compression to ventilation ratio in infants

A

30: 2 with one rescuer
15: 2 with two rescuers

19
Q

Compression to ventilation rate for children

A

30: 2 with one rescuer
15: 2 with two rescuers

20
Q

Ventilation rate for children and infants

A

1 breath every 3 to 5 seconds; about 1 second per breath; visible chest rise (12-20 breaths/min)

21
Q

Ventilations with advanced airway placed for children and infants

A

1 breath every 6 seconds (a rate of 10 breaths/min)
