Question
Given the following data, perform the appropriate calculations and evaluate the values related to oxygen content and oxygen consumption then determine whether each option below is correct or incorrect. Use A for correct and B for incorrect.
PaO2 = 95 mm Hg
SaO2 = 98%
Hb = 15 g/dl
PVO2 = 30 mm Hg
SVO2 = 50%
cardiac output = 3 l/min
CaO2 is approximately 20 cc O2/dl
a-v DO2 = 8 cc O2/dl
This patient's oxygen delivery is normal
VO2 is approximately 300 ml/minute
- A. B.CaO2 is approximately 20 cc O2/dl
- A. B.a-v DO2 = 8 cc O2/dl
- A. B.This patient's oxygen delivery is normal
- A. B.VO2 is approximately 300 ml/minute
Explanation / Answer
VO2 = Q (CaO2 - CvO2)
SvO2 = SaO2 - VO2/(Qx1.39x[Hb])
50 = 98 -VO2/ (3x1.39x15)
VO2 = 300.24 ml/ min which means approximately 300 ml/min
therefore, A
