Indirect Calorimetry

VO2 (mL/min)
VCO2 (mL/min)

Energy Expenditure
kCal/d
Respiratory Quotient

NB : precision is limited when FiO2>0.5.

Estimation of Qualitative Expenditure :

Carbohydrates
g/d
Lipids
g/d

Estimations based on Single Parameter :

Expenditure estimated from VO2
kCal/d
Expenditure estimated from VCO2
