A human calorimeter for the direct and indirect measurement of 24 h energy expenditure.
1. A calorimeter for the continuous measurement of heat production and heat loss in the human subject, for at least 24 h, is described. The calorimeter operated on the heat-sink principle for direct calorimetry and an open-circuit system for indirect calorimetry. 2. Sensible heat loss was measured using a water-cooled heat exchanger, and the temperature of water entering the heat exchanger was ...
متن کاملEnergy expenditure measured using indirect calorimeter after minimally invasive esophagectomy in ventilated postoperative patients.
Minimally invasive esophagectomy has recently become popular after the laparoscopic technique was developed. However, the postoperative energy expenditure in patients undergoing this procedure has not been evaluated. Therefore, we hypothesized that postoperative resting energy expenditure (REE) following minimally invasive esophagectomy is lower than that estimated using the Harris-Benedict equ...
متن کاملReproducibility of 24 h energy expenditure measurements using a human whole body indirect calorimeter.
Ten female subjects completed two similar experimental procedures (periods 1 and 2) to obtain values of reproducibility of energy intake and 24 h energy expenditure (24hEE) measurements in a whole body indirect calorimeter. The periods consisted of consumption of a provided weight-maintenance diet for 6-8 d, faeces and urine collection during the last 4 d and occupation of the calorimeter durin...
متن کاملA gradient-layer calorimeter for measurement of energy expenditure of infants.
We have developed and validated a gradient-layer calorimeter for direct measurement of energy expenditure of preterm infants. Infant calorimeters must be operated and tested differently from adult calorimeters, because the calorimeter must be warmed during operation to limit heat loss from the infant, the calorimeter wall temperature (which is selected on the basis of the infant's maturity) mus...
متن کاملA self-correcting indirect calorimeter system for the measurement of energy balance in small animals.
Indirect calorimetry involves measurement of CO(2) produced and O(2) consumed by an organism. These measurements are then used to calculate energy output, metabolic rate (MR), and respiratory quotient (RQ), a relative assessment of carbohydrate and lipid oxidation. By far the most difficult aspect of indirect calorimetry is measurement of O(2). Moreover, the abundance of O(2) (20.95%) relative ...
