unit 2- respiration & pulse oximetry
Show Answers:

  1. define ventilation
    exchange of oxygen and carbon dioxide in the lungs.
  2. define diffusion
    passage of oxygen and carbon dioxide between the alveoli and RBC, you measure it w/ pulse oximetry
  3. define perfusion.
    flow of blood to and from the pulmonary capillaries.
  4. Defien respiration. name 3 ways to describe it.
    • VS responsible for evaluating the ffectiveness of the ventilatory process of oxygen adn carbon dioxide exchange
    • rate= 12 to 20/min
    • depth
    • rhythm
  5. what are the normal value for pulse ox? what are the acceptable values?
    • 95-100%

  12. what is hypoxemia? what are complication and nursing interventions?
    • SaO2 <90%
    • ensure prope is on properly
    • confirm that oxygen delivery system is functioning
    • place client in semi-fowlers or fowlers position to maximize ventillation
    • encourage deep breathing
    • assess for signs of hypoexmia
    • assess/monitor VS, report significant findings to primary care provider
    • remain w/ the client and provide emotional support to decrease anxiety
  13. what are signs of hypoexmia?
    • tachypnea
    • tachycardia
