JB Learning: EMT Basic Chapter 13: BLS Resuscitation Exam Questions and Answers 100% Pass abdominal-thrust maneuver - Answer-The preferred method to dislodge a severe airway obstruction in adults and children; also called the Heimlich maneuver. active compression-decompression CPR - Answer-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. advanced life support (ALS) - Answer-Advanced lifesaving procedures, some of which are now being provided by the EMT. basic life support (BLS) - Answer-Noninvasive emergency lifesaving care that is used to treat medical conditions, including airway obstruction, respiratory arrest, and cardiac arrest. cardiopulmonary resuscitation (CPR) - Answer-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 - Answer-The total percentage of time during a resuscitation attempt in which active chest compressions are being performed. dependent lividity - Answer-Blood settling to the lowest point of the body, causing discoloration of the skin. gastric distention - Answer-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 - Answer-A combination of two movements to open the airway by tilting the forehead back and lifting the chin; not used for trauma patients. Hyperventilation - Answer-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. impendace threshold device (ITD) - Answer-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 - Answer-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 - Answer-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. load-distributing band (LDB) - Answer-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 - Answer-A device that depresses the sternum via a compressed gas-powered plunger mounted on a backboard. recovery position - Answer-A side-lying position used to maintain a clear airway in unconscious patients without injuries who are breathing adequately
