  1. Define anoxia
    condition of being wtithout oxygen
  2. What is the most common cause of respiratory insufficiency?
    obstruction of the airway
  3. How are airway obstructions reversed?
    positioning and suctioning
  4. Define hypoxemia
    • decreased amount of oxygen in the blood stream
    • may lead to hypoxia
  5. Define hypoxia
    reduced amount of oxygen available to meet cellular needs
  6. hypercapnia
    too much carbon dioxide in the bloodg
  7. What are the symptoms of hypoxia
    • restlessness
    • tachypnea
    • stridor
    • cyanosis
    • retractions (muscles move in during inspiration)
  8. Patients suffering from hypoxia are susceptible to....
    • respiratory infections due to insufficient inflation of the lungs
    • secretions pool providing a growth medium for microorganisms
  9. What does the pulse oximeter measure?
    • changes in arterial oxygen saturation
    • intravenous dye and jaundice reduce accuracy
    • levels below 90% is a signal of hypoxia
  10. What are the 2 standard methods of clearing secretions?
    deep breathing and coughing
  11. What is postural drainage
    • placing the patient in different positions to clear secretions in different segments of the lungs
    • each position should be done for 5 - 15 minutes
    • use a nebulizer to help make secretions thinner
    • ususally done in the AM 45 - 60 min before breakfast
  12. What are the 5 different instruments used to deliver oxygen?
    • cannula
    • mask
    • tent
    • croupette
    • catheter
  13. Which pieces of equipment are needed for oxygen therapy?
    • oxygen source
    • flowmeter
    • humidifier (optional)
    • tubing
    • required appliance
  14. What is the normal flow rate for administering oxygen?
    • 2 - 5 L/min (pg520)
    • 4 - 6 L/min (pg521)
  15. What are the (4) purposes of an artificial airway
    • relieve an obstruction
    • protect teh airway
    • facilitate suctioning
    • provide artificial ventilation
  16. Name the 2 types of pharyngeal airways
    • nasopharyngeal
    • oropharyngeal
  17. pharyngeal suctioning is required for
    • infants
    • gravely debilatated or unconcious
    • pts with ineffective cough
  18. Recommneded suction pressure
    80 - 120 mm hg
  19. When suction the _____ aseptic technique is mandatory
    trachea
