Abstract
In the first place the principle and properties of a hood method for measurement of metabolism during sleep are described. In the next place the hood system built by authors as a trial is described. This system consists of a hood, an electric blower, a wet gas meter and 300-liter gas bags. The dead space of the hood is about 10 liters. The blow rate was adjusted at 25, 30 and 40 l/min. The VO2 and VCO2 values were measured for 3 adult men, the correlation coefficients between the hood method and the Dougles bag method were 0.978 and 0.980, respectively. No relationship appeared between blow rate and accuracy of measurement.
