    Non-rebreather and partial non-rebreather masks
  3. For high-humidity. Oral surgery or non-compliance of other masks. Not for increase FiO2
    Face tents
  4. Fraction of inspired O2. Percent of gas patient is breathing that's made of O2.
  5. FiO2 of room air
  6. % 1 liter of oxygen increases FiO2
  7. % FiO2 of O2 with 1 liter per nasal cannula
  8. % FiO2 of O2 with 2 liters per nasal cannula?
  9. Can be standard or High-flow. usually 1-4 or 1-6 lpm. Needs humidity if >4L. May need humidity with less
    Nasal Cannula
  10. Low-flow
    simple mask
  11. Is oxygen a medication?
  12. FiO2 is > or = 50% for 24-48 hours
    Oxygen Toxicity
  13. Symptoms of oxygen toxicity.
    Sub-sternal chest pain. Dyspnea, Hypoxemia
  14. What is the target Sp O2 for patients with chronic hypercapnia?
  15. Which breathing technique strengthens the diaphragm?
  16. Breathing technique that prolongs expiration, increases airway pressure during expiration and reduces air trapping.
    Pursed lip breathing
  17. Is trach care a sterile or clean technique?
    In the hospital we use a sterile technique. The pt may use a clean technique at home.
  18. Precautions used for particles >; 5 microns. Influenza/Pneumonic Plague/Some Pneumonias (mycoplasma, meningococcal)
  19. Precautions for particles <; 5 microns including Shingles/TB/SARS
  20. Shingles Precautions
    Regular mask until lesions are dry.
  21. Precautions for TB
    N95 respiratory mask and negative pressure room
  22. Precautions for SARS
    N95 respiratory mask and contact precautions
  23. Precautions for MRSA & VRE
    Contact precautions only
  24. The two types of Positive Pressure Ventilation
    NIPPV (non-invasive positive pressure ventilation) and mechanical ventilation
  25. The two types of Non-invasive PPV
    CPAP and BiPAP
  26. What are the differences in the CPAP and BiPAP?
    CPAP is a continuous positive airway pressure to keep small airways open. BiPAP has a Bi-level positive airway pressure, different pressures for inhalation and exhalation
  27. Do endotracheal tubes need to be humidified?
  28. What is the normal cuff pressure on an endotracheal tube for an adult?
    15-25 mm/Hg
  29. What is a common problem with Trach cuffs?
    Pressure ulcers
  30. If a patient is ambulatory and has a chest tube, what needs to be done before they can get up?
    Disconnect the suction and leave it open to air
  31. What three things do you need to do after removal of the chest tube?
    Put an occlusive dressing such as Duoderm over the opening. Get a Chest X-ray. Monitor the patient.
  32. The 3 jobs of any chest tube.
    Prevent air from entering the pleural space. Drain air and/or fluid from the chest. Control suction (possibly).
  33. Will a trach always have a cuff?
  34. Best benefit of a trach?
    Decreased risk for aspiration
  35. Usual cause of URI's
    virus possibly strep
  36. What do you do for a nosebleed?
    Head forward, pinch bridge of nose for 15 minutes.
  37. How is Sleep Apnea diagnosed?
    O2 sats But 85% of the cases go undiagnosed.
  38. How effective are the BiPAP and CPAP for Sleep Apnea?
    95% effective
  39. What is Provigil?
    Drug used for Sleep Apnea. Has no cardiac side effects and has a low risk for abuse
  40. How effective is a tracheostomy for Sleep Apnea?
    100% But it is very invasive
  41. When can you clamp a chest tube?
    If the MD orders it or to change the system or check for leaks but be quick!!!
  42. What do you do if the chest tube is accidentally disconnected?
    Put the end in sterile saline or water. (This seals the system until it can be reconnected.)
  43. What should you do if the chest tube is accidentally dislodged for the patient?
    Use gauze and tape 3 sides. This will allow the air to be exhaled but not inhaled through the hole. If the air goes in the hole it will accumulate in the chest area and cause pressure on the lung.
  44. How will vitamin C help with URI's?
    May help with prevention.
  45. How will Echinacea help with URI's?
    May help treat symptoms-some may help decrease the duration.
  46. Do Probiotics help with URI's?
    They may help some.
  47. Will Ginsing help with treatment of URI's?
    Only if it is taken daily for 4 months before the symptoms first appear. It may cause HTN and agitation.
  48. What is Epitaxis? What is it a risk for? How can it be cured?
    It's a nosebleed. There is an increased risk for sinusitis if packing is used to stop it. Epi can be used on the packing to help decrrease the blood flow.
  49. Biggest thing to watch for with a nose fracture.
    May have a C-spine fracture. Monitor for clear fluid drainage (may be CSF). There may be rings on the dressing from the CSF mixing with the blood. Dipstick the clear fluid. If it is positive then it is CSF.
  50. Three things to do for a nose fracture.
    Elevate head/Use ice. Protect from re-injury for 6 weeks. May need ENT to realign bones.

    Sleep Study
  62. How do CNS depressants affect OSA?
