BLS resuscitation
| Term | Definition |
|---|---|
| Advanced Life Support | advanced lifesaving procedures used to treat medical conditions, such as cardiac monitoring |
| Basic Life Support | noninvasive emergency lifesaving care that is used to treat medical conditions, including airway obstruction, respiratory arrest and cardiac arrest |
| 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 |
| 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 BVM use |
| impedance threshold device | 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 chase 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 occured |
| load distributing band | 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 |
| return of spontaneous circulation | the return of a pulse and effective blood flow to the body in a patient who previously was in cardiac arrest |
| rigor mortis | stiffening of the body muscles; 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 |
| ventilation | exchange of air between the lungs and the environment, spontaneously by the patient or with assistance from another person such as an EMT |
