Complete & 100% Verified Solutions
aerobic metabolism - Answer ✔️ ✔️ -Metabolism that can proceed only in the presence of oxygen. agonal gasps - Answer ✔️ ✔️ -Occasional, gasping breaths that occur after the heart has stopped. airway - Answer ✔️ ✔️ -The upper airway tract or the passage above the larynx, which includes the nose, mouth, and throat. alveolar minute volume - Answer ✔️ ✔️ -The volume of air moved through the lungs in 1 minute minus the dead space; calculated by multiplying tidal volume and respiratory rate. American Standard Safety System - Answer ✔️ ✔️ -A safety system for large oxygen cylinders, designed to prevent the accidental attachment of a regulator to a cylinder containing the wrong type of gas. anaerobic metabolism - Answer ✔️ ✔️ -The metabolism that takes place in the absence of oxygen; the principal product is lactic acid. apnea - Answer ✔️ ✔️ -Absence of spontaneous breathing. aspiration - Answer ✔️ ✔️ -In the context of airway, the introduction of vomitus or other foreign material into the lungs. ataxic respiration - Answer ✔️ ✔️ -Irregular, ineffective respirations that may or may not have an identifiable pattern. automatic transport ventilator - Answer ✔️ ✔️ -A ventilation device attached to a control box that allows the variable of ventilation to be set. It frees the EMT to perform other tasks while the patient is being ventilated.
bag-valve mask - Answer ✔️ ✔️ -A device with a one-way valve and a face mask attached to a ventilation bag; when attached to a reservoir and connected to oxygen, it delivers more than 90% supplemental oxygen. barrier device - Answer ✔️ ✔️ -A protective item, such as a pocket mask with a valve, that limits exposure to a patient's body fluids. bilateral - Answer ✔️ ✔️ -A body part or condition that appears on both sides of the midline. bronchioles - Answer ✔️ ✔️ -Subdivision of the smaller bronchi in the lungs; made of smooth muscle and dilate or constrict in response to various stimuli. capnography - Answer ✔️ ✔️ -A noninvasive method to quickly and efficiently provide information on a patient's ventilatory status, circulation, and metabolism. Effectively measures the concentration of carbon dioxide in expired air over time. capnometry - Answer ✔️ ✔️ -The use of a capnometer, a device that measure the amount of expired carbon dioxide. carina - Answer ✔️ ✔️ -Point at which the trachea bifurcates into the left and right mainstem bronchi. chemoreceptors - Answer ✔️ ✔️ -Monitor the levels of oxygen, carbon dioxide, and the pH of the cerebrospinal fluid and then provide feedback to the respiratory centers to modify the rate and depth of breathing based on the body's needs at any given time. compliance - Answer ✔️ ✔️ -The ability of the alveoli to expand when air is drawn in during inhalation. continuous positive airway pressure - Answer ✔️ ✔️ -A method of ventilation used primarily in the treatment of critically ill patients with respiratory distress; can prevent he need for endotracheal intubation. dead space - Answer ✔️ ✔️ -The portion of the tidal volume that does not reach the alveoli and thus does not participate in gas exchange.
hypoxic drive - Answer ✔️ ✔️ -A condition in which chronically low levels of oxygen in the blood stimulate the respiratory drive; seen in patients with chronic lung diseases. inhalation - Answer ✔️ ✔️ -The active, muscular part of breathing that draws air into the airway and lungs. internal respiration - Answer ✔️ ✔️ -The exchange of gases between the blood cells and the tissues. intrapulmonary shunting - Answer ✔️ ✔️ -Bypassing of oxygen poor blood past nonfunctional alveoli to the left side of the heart. 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. labored breathing - Answer ✔️ ✔️ -Breathing that requires greater than normal effort; may be slower or faster than normal and usually requires the use of accessory muscles. larynx - Answer ✔️ ✔️ -A complex structure formed by many independent cartilaginous structures that all work together; where the upper airway ends and the lower airway begins; also called the voice box. manually triggered ventilation device - Answer ✔️ ✔️ -A fixed flow rate ventilation device that delivers a breath every time its button is pushed; also referred to as a flow-restricted, oxygen- powered ventilation device. mediastinum - Answer ✔️ ✔️ -Space within the chest that contains the heart, major blood vessels, vagus nerve, trachea, major bronchi, and esophagus; located between the two lungs. metabolism - Answer ✔️ ✔️ -The biochemical process that results in production of energy from nutrients within cells. mild airway obstruction - Answer ✔️ ✔️ -Occurs when a foreign body partially obstructs the patient's airway. The patient is able to move adequate amounts of air, but also experiences some degree of respiratory distress.
minute volume - Answer ✔️ ✔️ -The volume of air moved through the lungs in 1 minute; calculated by multiplying tidal volume and respiratory rate; also referred to as minute ventilation. nasal cannula - Answer ✔️ ✔️ -An oxygen-delivery device in which oxygen flows through two small, tubelike prongs that fit into the patient's nostrils; delivers 24% to 44% supplemental oxygen, depending on the flow rate. nasopharyngeal airway - Answer ✔️ ✔️ -Airway adjunct inserted into the nostril of an unresponsive patient or a patient with an altered level of consciousness who is unable to maintain airway patency independently. nasopharynx - Answer ✔️ ✔️ -The nasal cavity; formed by the union of facial bones and protects the respiratory tract form contaminants. nonrebreathing mask - Answer ✔️ ✔️ -A combination mask and reservoir bag system that is the preferred way to give oxygen in the prehospital setting; delivers up to 90% inspired oxygen and prevents inhaling the exhaled gases. oropharyngeal airway - Answer ✔️ ✔️ -Airway adjunct inserted into the mouth of an unresponsive patient to keep the tongue from blocking the upper airway and to facilitate suctioning the airway, if necessary. oropharynx - Answer ✔️ ✔️ -Forms the posterior portion of the oral cavity, which is bordered superiorly by the hard and soft palates, laterally by the cheeks, and inferiorly by the tongue. oxygenation - Answer ✔️ ✔️ -The process of delivering oxygen to the blood by diffusion from the alveoli following inhalation into the lungs. oxygen toxicity - Answer ✔️ ✔️ -A condition of excessive oxygen consumption resulting in cellular and tissue damage. parietal pleura - Answer ✔️ ✔️ -Thin membrane that lines the chest cavity. partial pressure - Answer ✔️ ✔️ -The term used to describe the amount of gas in air or dissolved in fluid, such as blood.
suction catheter - Answer ✔️ ✔️ -A hollow, cylindrical device used to remove fluid from the patient's airway. surfactant - Answer ✔️ ✔️ -A liquid protein substance that coats the alveoli in the lungs, decreases alveolar surface tension, and keeps the alveoli expanded; a low level in a premature infant contributes to respiratory distress syndrome. tension pneumothorax - Answer ✔️ ✔️ -A life-threatening collection of air within the pleural space; the volume and pressure have both collapsed the involved lung and cause a shift of the mediastinal structures to the opposite side. tidal volume - Answer ✔️ ✔️ -The amount of air that is moved in or out of the lungs during one breath. tonsil tips - Answer ✔️ ✔️ -Large, semirigid suction tips recommended for suctioning the pharynx; also called Yankauer tips. tracheostomy - Answer ✔️ ✔️ -Surgical opening into the trachea. ventilation - Answer ✔️ ✔️ -Exchange of air between the lungs and the environment, spontaneously by the patient or with assistance form another person, such as an EMT. visceral pleura - Answer ✔️ ✔️ -Thin membrane that covers the lungs. vital capacity - Answer ✔️ ✔️ -The amount of air that can be forcibly expelled from the lungs after breathing in as deeply as possible. vocal cords - Answer ✔️ ✔️ -Thin white bands of tough muscular tissue that are lateral borders of the glottis and serve as the primary center for speech production. wheezing - Answer ✔️ ✔️ -The production of whistling sounds during expiration such as occurs in asthma and bronchiolitis.
