A heart disease patient has an oximeter reading of 84%, use linear interpolation of the B. Use the alveolar equation PAO2-P102-PAC02/R assuming R8.B=565 mm C. Assume PACO2 will be constant at this value and calculate what PIO2 is needed so that table to estimate PaO2 FIO2 21 (pressurized airplane), PaO2 PAO2 and calculate PACO2. PA02-100 MM Hg D. Assume the subject is breathing at a constant 6 liters/min with a net inspired oxygen rate of 6*P102/(565-47) liters min, with x/2 suppled per minute from a nasal catheter (½ lost in expiration) supplied by an oxygen concentrator (100% O2), and the balance supplied from cabin air (21% oxygen)-use the P102 as calculated in C. Write the corresponding mass balance equation and calculate the required x value

Explanation / Answer

1. based on give data the pateient has on oximeter reading of 84% has the estimated PaO2 is 83.52

2. PAO2 = PIO2 - PACO2/R, R = 8, B = 565mm, FIO2= 21,

find PACO2

substituting above values

83.52 = (21+1)-PACO2/8

668 = 22 - PACO2

30.36 = PACO2

3. Find PIO2

PAO2 = PIO2-PACO2/R

83.52=PIO2-30.36/8

668=PIO2-30.36

22 = PIO2
