Chapter 14 Basic Life Support (BLS) Resuscitation Flashcards
(20 cards)
Advanced life-saving procedures, some of which are now being provided by the EMT
advanced life support
A device that depresses the sternum via a compressed gas powered or electric-powered plunger mounted on a backboard
mechanical piston device
The exchanged of air between the lungs and the environment; occurs spontaneously by the patient or with assistance from another person, such as an EMT
ventilation
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
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
recovery position
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
ischemia
Blood settling to the lowest point of the body, causing discoloration of the skin; a definitive sign of death
dependent lividity
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
impedance threshold device
A harsh, high-pitched respiratory sound, generally heard during inspiration, that is caused by partial blockage or narrowing of the upper airway; may be audible without a stethoscope
stridor
A technique that involes 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
The total percentage of time during a resuscitation attempt in which active chest compressions are being performed
Chest compression fraction
The return of a pulse and effective blood flow to the body in a patient who previously was in cardiac arrest
return of spontaneous circulation
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
cardiopulmonary resuscitation
The preferred method to dislodge a severe airway obstruction in adults and children; also called the Heimlich maneuver
abdominal thrust maneuver
Stiffening of the body muscles; a definitive sign of death
rigor mortis
A circumferential chest compression device composed of a constricting band and backboard that is either electrically or pneaumatically driven to compress the heart by putting inward pressure on the thorax.
load-distributing band
Noninvasive emergency life-saving care that is used to treat medical conditions, including airway obstruction, respiratory arrest, and cardiac arrest
Basic Life Support (BLS)
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 bag-mask device use
hyperventilation
A condition in which air fills the stomach, often as a result of high volume and pressure during artifical ventilation
gastric distention
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
