Chapter 13 Flashcards
Abdominal-thrust maneuver
Also called Heinrich maneuver, preferred method to dislodge a severe airway obstruction in adults and children
Chest compression fraction
The total percentage of time during a resuscitation attempt that in which active chest compressions are being preformed.
Dependent lividity
Look settling to the lower point of the body, causing discoloration of the skin; a definitive sign of death
Gastric distention
A condition in which air fills the stomach, often as a result of high volume and pressure during artificial ventilations
Hyperventilation
Rapid or deep breathing that lowers the blood carbon dioxide level below normal.
Impedance threshold device (ITD)
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
Ischemia
A lack of oxygen that deprives tissues of necessary nutrients, resulting from partial or complete blockage of blood flow
Load-distributing band (LDB)
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.
Mechanical piston device
a device that depresses the sternum via a compressed gas-powered or electric-powered plunger mounted on a backboard.
Recovery position
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
Rigor Morris
Stiffening of the body muscles; a definitive sign of death
Stridor
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
Ventilation
Exchange of air between the lungs and the environment
Compression rate on infants, children, and adults
100-120 Beats a minute
Compression depth for children and infants
Children- 2 inches and 5 centimeters
Infants- 1.5 inches
