Nomograms for calculation of heat loss.
Two nomograms are presented. The first enables the mean surface and body temperatures and the body heat content of a patient of given weight to be determined from measurements of skin temperature at three sites and of the core (rectal) temperature. The second enables the change in heat content of such a patient to be determined from the change in mean body temperature.
متن کاملNomograms for calculation of urea clearance.
Two nomograms are given for use in calculating standard, C3, or maximum, Cm, urea clearance. The first nomogram calculates the urine flow rate, f, from the urine collection time and volume data. With the second nomogram, values of f and urea nitrogen concentrations in blood serum (or plasma) and urine are used to calculate either C3 or Cm, according to the value of f. There is no intermediate c...
متن کاملNomograms for calculation of oxygen consumption and respiratory exchange ratio.
Nomograms have been prepared whereby the respiratory exchange ratio may be derived from the concentrations of carbon dioxide and oxygen in expired gas and oxygen consumption from the volume and oxygen concentration of expired gas; they apply only to patients breathing room air. The nomogram for the respiratory exchange ratio has an error of less than 0.01, which is the limit of visual discrimin...
متن کاملEarly weight loss nomograms for exclusively breastfed newborns.
BACKGROUND The majority of newborns are exclusively breastfed during the birth hospitalization, and weight loss is nearly universal for these neonates. The amount of weight lost varies substantially among newborns with higher amounts of weight loss increasing risk for morbidity. No hour-by-hour newborn weight loss nomogram exists to assist in early identification of those on a trajectory for ad...
متن کاملEntropy generation calculation for laminar fully developed forced flow and heat transfer of nanofluids inside annuli
In this paper, second law analysis for calculations of the entropy generation due to the flow andheat transfer of water-Al2O3 and ethylene glycol-Al2O3 nanofluids inside annuli is presented. Thephysical properties of the nanofluids are calculated using empirical correlations. Constant heatfluxes at inner surface of the annuli are considered and fully developed condition for fluid flowand heat t...
