? Benedict-Roth Apparatus

--- Content provided by​ FirstRanker.com ---

? Calculates an amount of

Oxygen consumed under a

? Calculated per sq.m of body surface per

hour
? Indirect Calorimetry:

Calculates Respiratory Quotient

? Oxygen Consumption

? Carbon Dioxide Production

an amount of Oxygen

consumed and Carbon dioxide

produced.

? Respiratory Quotient (RQ) is

ratio of volume of carbon

dioxide produced to volume of

Oxygen consumed by an

individual in a given interval of

time.

Respiratory Quotient (RQ)
