Chapter 13 Vocab Flashcards
(19 cards)
the preferred method to dislodge a severe airway obstruction in adults and children; also called the heimlich maneuver
abdominal-thrust maneuver
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 that returns to the heart and, thus, the amount of blood ejected from the heart during the compression phase
active compression-decompression CPR
advanced life saving procedures used to treat medical conditions, such as cardiac monitoring, administration of intravenous fluids and medications, and the use of advance airway adjuncts. EMTs may be trained in some of these areas
ALS
advance life support
the combination of chest compressions and rescue breathing used to establish adequate ventilation and circulation in a patient who is not breathing and has no pulse
CPR
cardiopulmonary resuscitation
the total percentage of time during a resuscitation attempt in which active chest compressions are being performed
chest compression fraction
blood settling to the lowest point of the body, causing discoloration of the skin; a definitive sign of death
dependent lividity
a condition in which air fills the stomach, often as a result of high volume and pressure during artificial ventilation
gastric distention
a combination of two movements to open the airway by tilting the forehead back and lifting the chin; not used for trauma patients
head tilt-chin lift maneuver
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 BVM sue
hyperventilation
a valve device placed between the endotracheal tube and a bag-valve mask that limits the amout of air entering the lungs during the recoil phase between chest compressions
ITD
impedance threshold device
a lack of oxygen that deprives tissues of necessary nutrients, resulting form partial or complete blockage of blood flow; potentially reversible because permanent injury has not yet occured
ischemia
technique to open the airway by placing the fingers behind the angle of the jaw and bringing the jaw forward; used for patients who may have a cervical spine injury
jaw-thrust maneuver
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
LDB
load-distributing band
a device that depresses the sternum via a compressed gas-powered or electrical-powered plunger mounted on a backboard
mechanical piston device
a side-lying potion 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
recovery postion
the return of a pulse and effective blood flow to the body in a patient who previously was in cardiac arrest
ROSC
return of spontaneous circulation
stiffening of the body muscles; a definitive sign of death
rigor mortis
a harsh, high-pitched respiratory sound, generally heard during inspirations, that is caused by partial blockage or narrowing of the upper airway; may be audible without a stethescope
stridor
exchange of air between the lungs and the environment, spontaneously by the patient or with assistance from another person, such as an EMT
ventilation
