Capillary blood pH by a dilution technic.
نویسندگان
چکیده
A technic is described for collecting arterialized capillary blood in a small heparinized polyethylenecentrifuge tube. The pH is measuredafter dilution and injection into a BeckmanmicrobloodpH Assembly. Dilution of the blood with saline results in an averageincreaseof 0.027 pH units. This changein pH on dilution is eliminated by inclusionof calcium in the diluent. The pH of capillary blood drawn and measuredasdescribeddoesnot differ significantly from that of undiluted arterial blooddrawn from the same patient.

متن کاملMeasurement of Pulmonary Blood Flow Using the Indicator-Dilution Technic in Patients with a Central Arteriovenous Shunt
The possibility of measuring pulmonary blood flow in patients with central arteriovenous shunts utilizing the initial portion of indicator-dilution curves was explored in 16 patients by comparing these values for pulmonary blood flow with determinations by the direct Fick method. A good correlation between Fick and indicator-dilution values was obtained, and no systematic differences were demon...

متن کاملAn appraisal of the double indicator-dilution method for the estimation of mitral regurgitation in human subjects.
T HE shape of an indicator-dilution curve is determined by at least 4 variables: cardiac output, the volume between the injection site and the sampling site, the presence of a left-to-right intracardiac shunt, and the presence of valvular regurgitation.1-3 In the absence of an intracardiac shunt and valvular regurgitation, one can predict the downslope of the arterial dilution curve, using the ...
متن کاملEvaluation of mitral insufficiency in dogs by electronic analog simulation of radioisotope dilution data.
Left atrial and left ventricular volumes, regurgitant flows and systolic efficiencies have been calculated for dogs with and without mitral valve insufficiency, using a technic of electric analog simulation of radioisotope dilution data. Amounts of blood between the valve of the pulmonary artery and the left atrium were calculated by use of mean transit time and flow, and compared to those of t...
