Unformatted text preview: ice that because c is proportional to P, that increasing P by 4x would likewise increase c by 4x. So c-99=4*5e-4. To find the volume, substitute into the ideal gas law: pV nRT V nRT / p n (c c0 ) *5L 0.0015*5 .0075mol T 37C 273.15 Latm R 0.082057 molK p 0.79atm V 0.242L 5. (10 points) The total lung capacity of a patient is 5.9 L. If the patient's inspiratory capacity was found to be 3.3 L using spirometry, what would be the patient's functional residual capacity? What would you need to measure to determine the patient's residual volume? (Question and answer taken from Introduction to biomedical engineering by John Denis Enderle, Joseph D. Bronzino and Susan M. Blanchard) a. TLC = IC + FRC; 5.9L = 3.3L + FRC; Therefore, FRC = 2.6 L b. RV = TLC VC. You would need to measure the patient's vital capacity (VC)....
