  1. which pts are at a greater risk of upper airway obstruction
    macroglossia- enlarged tongue
  2. if the pt iis conscious and has a partial airways obstruction, the pt should be
    monitored closely and allowed to try to relieve the obstruction on their own
  3. what should the RT do if the pt is conscious and has a COMPLETE airway obstruction caused by food or a foreign object,
    abdominal thrusts CPR
  4. if the pt is unconscious and has a partial or complete airway obstruction what should the RT do
    head tilt and chin lift
  5. oropharyngeal airway must only be used on what type of pts
    unconscious pt
  6. oropharyngeal airway maintains a patent airway by lying between the ____ of the tongue and the _____ wall of the pharynx
    • base
    • posterior
  7. measure the oropharyngeal airways from the
    corner of the lip to the angle of the jaw
  8. nasopharyngeal airway maintains a patent airway by lying btwn the ____ of the tongue and the ____ wall of the pharynx
    • base
    • posterior
  9. measure the nasopharyngeal airway from the
    tip of the nose to the earlobe
  10. lubricate the airway with a
    water-soluable gel
  11. the nasopharyngeal airway is tolerated with what type of pts
  12. nasopharyngeal airway is most commonly used to facilitate
    nasotracheal suctioning
  13. laryngeal mask airway LMA is designed to be used as an
    alternative to a face mask for achieving and maintaining control of the airway during SURGERY when tracheal intubation is not necessary or in emergencies when ET intubation CANNOT be accomplished after several attempts
  14. LMA are available in which sizes
    all sizes in all ages
  15. what do you use to advance the LMA until resistance is met
    index finger
  16. indications for esophageal tracheal combitube ETC
    • difficult face mask fit
    • unsuccessful intubation and difficulty ventilating w/ bag mask
    • no one available that has been trained in endotracheal intubation
  17. indications for ET tubes
    relief of upper airway obstruction resulting from laryngosparm, epiglottitis or glottic edema
  18. laryngoscope- miller has what type of blade
  19. laryngoscope- mcintosh has what type of blade
  20. the curved blad- mcintosh should be inserted ____ the ____ and the ____ of the tongue which is the _____
    • btwn
    • epiglottis
    • base
    • vallecula
  21. the straight blade- miller should be placed ___ the ____ and lifted upward and forward to expose the _____
    • under
    • epiglottis
    • vocal cords
  22. end tidal CO2 levels are generally around
  23. if the tube is in the esophagus, the end tidal CO2 reading remains near
  24. during the resuscitative procedures when cardiac output and blood pressure are low, gas exchange is reduced and the CO2 detector may read near zero even when the ET tube is in the
  25. avg distance from the teeth to the carina is
  26. the end of the tube should rest __ to ___ cm above the carina
    2 to 5
  27. what is considered nonemergent tubes
    nasotracheal tubes
  28. magill forceps are used to facillitate
    nasotracheal intubation
  29. this tube has a port to allow for continuous or intermittent suctioning of subglottic secretions
    high lo evac tube
  30. high lo evac tube are used to help prevent
    VAP- vent acquired pneumonia
  31. if after changing a tracheostomy tube, you observe subq emphysema and resp distress and can auscultate little or no air movement, the tube is
    malpositioned and must be revoved immediately; ventilate the pt's lungs by bag-mask
  32. this tube is used to aid in weaning the pt from a tracheostomy tube and to allow the pt to talk
    fenestrated tube
  33. this airway consists of a short, hallow tube that is used to replace the tracheostomy tube but can still maintain a patent stoma in case problems arise

    pt has complete use of the upper airway
    tracheostomy button
  34. this airway is used to wean pts from tracheostmy tubes while maintaining a patent stoma.

    they have one way valve on the proximal end of the tube.
    kistner tracheostomy tube
  35. tubes should employ what type of volumes and pressure
    • high vol
    • low pressure
  36. excessive air in the cuff will act as what type of pressure
    high pressure
  37. maximum cuff pressure is
    25mmHg or 34 cmHg
  38. if the cuff is inflated above maximum cuff pressure, continue inflating the cuff using the MLT or MOV it may be that the ET tube is
    too small, replace for a larger one
  39. another alternate to saline lavage is to instill
    • acetylcysteine (mucomyst)
    • sodium bicarbonate (2%)
  40. what is the acceptable size catheter inside a diameter of the ET tube
  41. formula to estimate proper catheter size
    multiply the internal diameter of the ET tube by 2, then use the next smallest catheter size
  42. what is the proper size of catheter to use when suctioning an 8.0 mm ETT
    8.0 X 2 = 16 = the next smallest size cath which would be 14 Fr
  43. closed suction catheter results in less potential for
    • cardiac arrhythmias
    • desaturating during the suction procedure
