Chapter 14 - BLS Resuscitation Flashcards
(20 cards)
Abdominal thrust maneuver
The preferred method to dislodge as severe airway obstruction in adult and children; also called the Heimlich maneuver
Active compression-decompression CPR
A technique that involves compressing the chest, and then actively pulling it back up to who its neutral position or beyond (decompression); they increase the amount of blood that returns to the heart, and, thus, the amount of blood ejected from the heart during the compression phase
Advanced Life Support (ALS)
Advanced, life-saving procedures, some of which are now being provided by the EMT
Basic Life Support (BLS)
Non-invasive emergency, life-saving care that is used to treat medical conditions, including airway obstruction, respiratory arrest, and cardiac arrest
Cardiopulmonary resuscitation (CPR)
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
Chest compression fraction
The total percentage of time during a resuscitation attempt in which active chest compressions are being performed
Dependent lividity
Blood settling to the lowest 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 ventilation
Head tilt-chin lift maneuver
A combination of two movements to open the airway by tilting the forehead back and lifting the chin; not used for trauma patients
Hyperventilation
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
Impedance Threshold Device (ITD)
A valve device placed between the endotracheal tube and a bag-mask device that limits the amount of air entering the lungs during the recall phase between chest compressions
Ischemia
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
Jaw-thrust maneuver
Technique to open the airway by placing the fingers behind the ankle of the jaw and bringing the jaw forward; use for patients who may have a cervical spine injury
Load-distributing band (LDB)
A circumferential chest compression device composed of a constricting band and backboard that is either electronically 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 i. unresponsive patients who are breathing adequately and do not have suspected injuries to the spine, hips, pelvis.
Return of Spontaneous Circulation (ROSC)
The return of a pulse and effective blood flow to the body in a patient who previously was in cardiac arrest
Rigor mortis
Stephanie of the body muscle; a definitive sign of death
Stridor
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
Ventilation
The exchange of air between the lungs and the environment, spontaneously by the patient or with assistance from another person, such as an EMT
