    • -deliver consistent Fio2 regradless of breathing pattern
    • -it is useful when accuracy of delivery is essential
  21. when doing a focused assessment you must assess the respiration?
    • -depth
    • -rate
    • -character
    • (Rationale: although rate may be within normal limits; the patient may be breathing very shallowly and consequently not oxygenating well.)
  22. what symptoms indicate the patient should be assessed for possible hypoxia?

    • (rational: these can all indicate that the patient is not obtaining enough oxygen)
  23. how can you reverse slight hypoxia?
    you can reverse slight hypoxia by turning, coughing, and deep breathing
  24. where is the best place to check for cyanosis in dark skinned people?
    inside the mouth
  25. Deep rattling cough indicates ___________.
    retained secretions
  26. shallow raspy cough may indicate ____________.
    throat irritation
  27. sputum produce in the morning may indicate _________ rather than _________
    sinus drainage, a problem in the lungs

    is the inability of the body to meet its oxygen needs and remove excess amounts of carbon dioxide
  30. what is the most common cause of respiratory insufficiency?
    Airway obstruction
  31. what is one of the first signs of hypoxia?
    irritability or restlessness
  32. what affects do hypoxia have on the body system?
