Show Answers:

  1. A safety system for oxygen cylinders, designed to prevent the accidental attachment of a regulator to a cylinder containing the wrong type of gas.
    American Standard System
  2. A protective item, such as a pocket mask with a valve, that limits exposure to a patient''s body fluids.
    barrier device
  3. The active, muscular part of breathing that draws air into the airway and lungs.
  4. The upper airway tract or the passage above the larynx, which includes the nose, mouth, and throat.
  5. The biochemical processes that result in production of energy from nutrients within the cells.
  6. The passive part of the breathing process in which the diaphragm and the intercostal muscles relax, forcing air out of the lungs.
  7. Occurs when a foreign body completely obstructs the patient''s airway. Patients cannot breathe, talk, or cough.
    complete airway obstruction
  8. A condition in which chronically low levels of oxygen in the blood stimulate the respiratory drive; seen in patients with chronic lung diseases.
    hypoxic drive
  9. Airway adjunct inserted into the nostril of a conscious patient who is unable to maintain airway patency independently.
    nasopharangeal adjunct
  10. A lack of oxygen that deprives tissues of necessary nutrients.
  11. Condition in which an obstruction leaves the patient able to exchange some air, but also causes some degree of respiratory distress.
    partial airway obstruction
  12. Pressure on the cricoid cartilage; applied to occlude the esophagus in order to inhibit gastric distention and regurgitation of vomitus in the unconscious patient.
    cricoid pressure
  13. Movements in which the skin pulls in around the ribs during inspiration.
  14. A side-lying position used to maintain a clear airway in unconscious patients without injuries who are breathing adequately.
    recovery position
  15. Exchange of air between the lungs and the environment, spontaneously by the patient or with assistance from another person, such as an EMT-B.
  16. The amount of air moved in or out of the lungs during one breath.
    tidal volume
  17. A process in which molecules move from an area of higher concentration to an area of lower concentration.
  18. 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.
    nasal cannula
  19. A normal reflex mechanism that causes retching; activated by touching the soft palate or the back of the throat.
    gag reflex
  20. A term used to distinguish the degree of distress in a patient with a partial airway obstruction. With good air exchange, the patient is still conscious and able to cough forcefully, although wheezing may be heard.
    good air exchange
  21. 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, delivers more than 90% supplemental oxygen.
  22. A hollow, cylindrical device used to remove fluid from the patient''s airway.
    suction catheter
  23. A partial or complete accumulation of air in the pleural space.
  24. A dangerous condition in which the body tissues and cells do not have enough oxygen.
  25. Difficulty breathing.
  26. An opening through the skin and into an organ or other structure; a stoma in the neck connects the trachea directly to the skin.
  27. Airway adjunct inserted into the mouth to keep the tongue from blocking the upper airway and to facilitate suctioning the airway.
    oropharangeal airway
  28. The volume of air moved through the lungs in 1 minute; calculated by multiplying tidal volume and respiratory rate.
    minute volume
  29. The ability of the alveoli to expand when air is drawn in during inhalation.
  30. 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.
    jaw-thrust maneuver
  31. A combination of two movements to open the airway by tilting the forehead back and lifting the chin; not used for trauma patients.
    head tilt-chin lift maneuver
  32. Open, clear of obstruction.
  33. 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 (carbon dioxide).
  34. Occasional, gasping breaths that occur after the heart has stopped.
    agonal respiration
  35. The introduction of vomitus or other foreign material into the lungs.
  36. A technique that is used to prevent gastric distention in which pressure is applied to the cricoid cartilage; also referred to as cricoid pressure.
    Sellick maneuver
  37. A system established for portable cylinders to ensure that a regulator is not connected to a cylinder containing the wrong type of gas.
    pin-indexing system
  38. Breathing that requires greater than normal effort; may be slower or faster than normal and usually requires the use of accessory muscles.
    labored breathing
  39. A condition in which air fills the stomach, often as a result of high volume and pressure during artificial ventilation.
    gastric distention
  40. A term used to describe the degree of distress in a patient with a partial airway obstruction. With poor air exchange, the patient often has a weak, ineffective cough, increased difficulty breathing, or possible cyanosis and may produce a high-pitched noise during inhalation (stridor).
    poor air exchange
  41. tonsil tips
    Large, semirigid suction tips recommended for suctioning the pharynx; also called Yankauer tips.
  42. bilateral
    A body part that appears on both sides of the midline.
  43. apnea
    A period of not breathing.
  44. ataxic respirations
    Irregular, ineffective respirations that may or may not have an identifiable pattern.
