Question

8) A patient is breathing through an oxygen mask that delivers 95% 0,13% N. They are in Baltimore, Maryland (oea level), so assume a total pressure of 760mm is the partial pressure of O that they are What 9) For the patient above, how does this increase in Poa in the "atmosphere" affect the partial pressure of CO2 in the alveolus? (hint: think about where the CO is coming from and compare this patient to a "normal" patient, not breathing through a mask) 10) As part of an assessment on an incoming student-athlete, you measure her resting respiratory rate at 9 breaths per minute and her tidal volume at 490ml. What is her minute volume? This student athlete happens to play basketball, which is not surprising, since she's 6-4” tall. The anatomical dead space of her respiratory system is 160 ml, what is her alveolar minute volume (at 9 breaths per minute and a tidal volume of 490 ml)? 11) 12) Now you put this student athlete on a treadmill and have her exercise to near maximal effort. Her respiratory rate rises to 19 breaths per minute and her respiratory volume increases to 3100 ml. What is her new minute volume (total, not alveolar)? Round this to the nearest liter

Explanation / Answer

8) inspired oxygen = 95% = 0.95

atmospheric pressure = 760 mmHg

partial pressure of O2 = 0.95*760 mmHg

= 722 mmHg
