Agonal Respiration Apnea Chapter 7 Chapter 7 Aspiration Complete Airway Obstruction Chapter 7 Chapter 7 Cricoid Pressure Chapter 7 Gastric Distention Chapter 7 Diffusion Chapter 7 Hypoxia Chapter 7 A period of not breathing. Slow, gasping respiration, sometimes seen in dying patients. These respirations are not sufficient to support life. Occurs when a foreign body completely obstructs the patient's airway. Patients cannot breathe, talk, or cough. Cough is ineffective. The introduction of vomitus or other foreign material into the lungs. A process in which molecules move from an area of higher concentration to an area of lower concentration. Pressure on the cricoid cartilage; applied to occlude the esophagus in order to inhibit gastric distention and regurgitation of vomitus in the unconscious patient. A dangerous condition in which the body tissues and cells do not have enough oxygen. A condition in which air fills the stomach, often as a result of high volume and pressure during artificial ventilation. Hypoxic Drive Inhalation Chapter 7 Chapter 7 Ischemic Metabolism Chapter 7 Chapter 7 Nasopharyngeal airway Chapter 7 Recovery Position Oropharyngeal airway Chapter 7 Retractions Chapter 7 Chapter 7 The active, muscular part of breathing that draws air into the airway and lungs. A "backup system" to control respiration; senses drops in the oxygen level in the blood. The biochemical processes that result in production of energy from nutrients within the cells. A restriction in blood supply, generally due to factors in the blood vessels, with resultant damage or dysfunction of tissue. A curved piece of plastic inserted over the tongue that creates an air passage way between the mouth and the posterior pharyngeal wall. Airway that is inserted through one nostril to create an air passage between the nose and the nasopharynx. The NPA is preferred to the OPA in conscious patients because it is better tolerated and less likely to induce a gag reflex. Movements in which the skin pulls in around the ribs during inspiration A side-lying position used to maintain a clear airway in unconscious patients without injuries who are breathing adequately. Sellick Maneuver Chapter 7 Compliance Tidal Volume Chapter 7 Cheyne-Stokes Respirations Chapter 7 Chapter 7 Exhalation Dyspnea Chapter 7 Chapter 7 Pin-Indexing System Pneumothorax Chapter 7 Chapter 7 The amount of air that is exchanged with each breath. An abnormal pattern of breathing characterized by period’s rapid deep respirations followed by periods of apnea. A technique that is used to prevent gastric distention in which pressure is applied to the cricoid cartilage; also referred to as cricoid pressure. The ability of the alveoli to expand when air is drawn in during inhalation. Difficulty breathing. The passive part of the breathing process in which the diaphragm and the inter-costal muscles relax, forcing air out of the lungs. A partial or complete accumulation of air in the pleural space. A system established for portable cylinders to ensure that a regulator is not connected to a cylinder containing the wrong type of gas. Stoma Ventilation Chapter 7 Chapter 7 Minute Volume Surfactants Chapter 7 Chapter 7 Edema Rhonchi Chapter 7 Chapter 7 BVM Chapter 7 NRB Chapter 7 Exchange of air between the lungs and the environment, spontaneously by the patient or with assistance from another person, such as an EMT-B. An opening through the skin and into an organ or other structure; a stoma in the neck connects the trachea directly to the skin. Wetting agents that lower the surface tension of a liquid, allowing easier spreading, and lower the interfacial tension between two liquids. The volume of air moved through the lungs in 1 minute; calculated by multiplying tidal volume and respiratory rate. These are low pitched, snore-like sounds. They are caused by airway secretions and airway narrowing. They usually clear after coughing. Swelling of any organ or tissue due to an accumulation of excess fluid without an increase of the number of cells in the affected tissue.
