EMT AIRWAY EXAM QUESTIONS WITH UPDATED&VERIFIED ANSWERS AND A GUARANTED 100% PASS vocal cords thin whit bands of tough muscular tissue that are lateral borders of the glottis and serve as a the primary center for speech production poor air exchange term used to describe the degree of distress in a patient with a mild airway obstruction. This causes the patient to have a weak ineffective cough, increased difficulty breathing or possible cyanosis and may produce high pitched noise during inhalation pulse oximetry an assessment tool that measure oxygen saturation of hemoglobin in the capillary beds recovery position a side lying position used to maintain a clear airway in unconscious patients without injuries who are breathing adequately wheezing the production of whistling sounds during expiration such as occurs in asthma and bronchiolitis Acidosis The buildup of excess acid in the blood or body tissues that results from a primary illness Adventitious breath sounds abnormal breath sounds such as wheezing stridor rhonchi and crackles Bronchioles Subdivision of the smaller bronchi in the lungs; made of smooth muscle and dilate or constrict in response to various stimuli Copnography a noninvasive method to quickly and efficiently provide information on a patient's ventilatory status, circulation and metabolism. Effectively measures the concentration of CO2 in expired over time Capnometry A device that measures the amount of expired CO2, capnometer Carina point at which the trachea bifurcates into the left and right mainstem bronchi Chemoreceptors monitor the levels of O2, CO2, and the pH of the cerbrospinal fluid and then provide feedback to the resp. centers to modify the rate and depth of breathing based on the body's needs Compliance Ability of the alveoli to expand when air is drawn in during inhalation Continous Positive airway pressure (CPAP) method of ventilation used primarily in the treatment of critically ill patients with resp. distress; can prevent the need for endotracheal intubation dead space portion of the tidal volume that does not reach the alveoli and thus does not participate in gas exchange gag reflex a normal reflex mechanism that causes retching; activated by touching the soft palate or the back of the throat. gastric distention condition in which are fills the stomach, often as a result of hight volume and pressure during artificial ventilation glottis the space in between the vocalcords that is the narrowest portion of the adult's airway; also caled the glottic opening good air exchange a term used to distinguish the degree of distress in a patient with a mild airway obstruction. with good air exchanged the patient is still conscious and able to cough forcefully, although wheezing may be heard. head-tilt-chin lift maneuver combination of two movements to open the airway by tilting the forehead back and lifting the chin; not used for trauma patients hypercarbia increased carbon dioxide level in the bloodstream hypoxia a dangerous condition in which chronically low levels of oxygen in the blood stimulate the respiratory drive; seen in patients with chronic lung diseases. inhalation the active muscular part of breathing that draws air into the airway and lungs internal respiration the exchanged of gases between the blood cells and the tissues intrapulmonary shunting bypassing of oxygen-poor blood past nonfunctional alveoli to the left side of the heart jaw-thrust maneuver 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 breathing that requires greater than normal effort; may be slower or faster than normal and usually requires the use of accessory muscles What is the amount of air that normally reaches the alveoli in an adult? 350 mL An unresponsive 43 year old male is cool, pale, diaphoretic and breathing 6 times a minute. Which device should you use to administer oxygen? BVM How should you insert a nasopharyngeal airway? Face the bevel towards the septum. (The first correct step when inserting a NPA is to face the bevel towards the septum. Apply a H2O soluble lubricant, do not use an oil base lubricant) A febrile 44 year old male complains of shortness of breath and has dull chest pain. he has been coughing up rusty sputum for the last 3 days. What is the most likely cause? Pneumonia Larynx 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 voicebox manually triggered ventilation device 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 space within the chest that contains the heart, major blood vessels, vagus nerve, trachea, major bronchi, and esophagus; located between the two lungs metabolism/cellular respiration the biochemical process that result in production of energy from nutrients within the cell
