Blood Density Is Nearly Equal to Water Density: A Validation Study of the Gravimetric Method of Measuring Intraoperative Blood Loss
Purpose. The gravimetric method of weighing surgical sponges is used to quantify intraoperative blood loss. The dry mass minus the wet mass of the gauze equals the volume of blood lost. This method assumes that the density of blood is equivalent to water (1 gm/mL). This study's purpose was to validate the assumption that the density of blood is equivalent to water and to correlate density with ...
متن کاملA Novel Method for Measuring Energy Loss in Electron Rings
∗ This work was supported by the U.S. Department of Energy under Contract No. DE-AC03-76SF00098. Abstract We present a novel method for measuring the energy loss per turn in an electron storage ring. The method involves the accurate measurement of the change in the rotation period of an uncaptured electron bunch using a dual-sweep streak camera. In our opinion, this method is more direct and ac...
متن کاملA Microcolorimetric Method for Measuring the Oxygen Saturation of Blood
For purposes of measuring oxygen saturation in the arterial blood of newly born infants (1) it became necessary to develop a rapid and reasonably accurate method for small blood samples. It was further necessary to demonstrate that cutaneous blood samples could be considered identical with specimens drawn directly from an artery. The present communication describes the calorimetric method evolv...
متن کاملAn improved method for measuring blood concentrations of phenylpyruvic acid.
We describe an improved determination of phenylpyruvic acid (PPA) in blood plasma by ultraviolet spectrophotometric measurement of an enolborate complex. Sensitivity and recovery are well suited for accurate analy. sis in the range of 1.25 to 25 mg/liter. Sera from 10 fasting phenylketonuric subjects averaged 15.3 mg/liter (range, 4.8 to 25.0 mg/liter). A pronounced diurnal rhythm in plasma PPA...
