A
= 6 CO2/6 O2 = 1.0
2
Q
what is the RQ of palmitic acid?
A
= 16 CO2 / 23 O2 = 0.696
3
Q

A
63 CO2/ 77 O2 = 0.818
4
Q
What is the calculation of VO2?
A
(FIO2 - FEO2) x ventilatory rate
5
Q
what is FIO2?
A
it’s the rooms air value as a percentage
6
Q
what is FEO2?
A
it’s the exhaled gas value as a percentage
7
Q
what is the ventilatory rate?
A
total volume of exhaled gas
8
Q
what is the calculation of VCO2?
A
(FECO2 - FICO2) x ventilatory rate
9
Q
if we’re using kcal/min, what is the equation for EE?
A
3.94 VO2 (ml/min) + 1.10 VCO2 (ml/min)
10
Q
How to convert from ml/min to kcal/min?
A
dividing the value by 1000
11
Q
What is the equation, if we use the Weir equation to calculate EE in kcal?
A
- 90 VO2 (l) + 1.10 VCO2 (l)
note: it’s in L
