The flashcards below were created by user lbethune on FreezingBlue Flashcards. What would you like to do?


  1. injectable

    • deliver 100% O2 for 3 min
    • gradually increase to 5% iso
    • either maintain on mask or intubate
  32. prevents cardiac arythmias
    allows for patient adjustment to the smell of iso
    struggling may occur after 2-3 min
    purpose of gradual increase with mask technique
  33. analgesia
    unpleasant sensory or emotional experience associated with actual or potential tissue damage, relief of pai without loss of consciousness
  34. mild, moderate and severe
    3 classifications of pain intensity
  35. acute
    abrupt onset, relatively short, usually treatable (type of pain)
  36. chronic
    slow onset, long duration, potentially manageable (type of pain)
  37. increased heart rate, blood pressure, respirations and dilated pupils
    physiological signs of pain
  38. endorphins

    anesthetist ensures that an increased volume of air is delivered to the patient, although patient initiates each inspiration
  61. controlled ventilation
    externally initiated by anesthetist, patient does not make spontaneous repirations
  62. positive pressure ventilation (PPV)
    ensures patient receives adequate O2 and is able to exhale adequate amounts of O2
  63. hypercarbia
