Low‐flow anaesthesia at a fixed flow rate
Acta Anaesthesiologica Scandinavica, 2009Aims and Objectives: This study attempts to assess the safety of low‐flow anaesthesia (LFA) at fixed flow rates with particular reference to the incidence of a decline in FiO2 below safe levels of 0.3 and to determine whether LFA can be used safely in the absence of an FiO2 monitor.Methods: A total of 100 patients undergoing procedures under general ...

High-flow-rate hydroxylapatites
Analytical Biochemistry, 1985We have established a novel and simple method for preparing rigidly crystallized or granulated hydroxylapatites, which showed flow rates one order of magnitude higher in column chromatography than those of the Tiselius specimen (1). The essential difference in the procedures from the Tiselius method is that calcium phosphate, the precursor of ...

Estimation of heat-flow rate from fluid-flow rate
Journal of Petroleum Science and Engineering, 2020Abstract This paper presents a simplified analytical model to translate the fluid-flow rate into the heat-flow rate by incorporating the Joule-Thompson effect. Single-phase fluid flow in the formation and into the wellbore is the prime consideration of this study. The proposed approach combines the Darcy flow equation with that of Fourier's heat flow

Maximum Flow Rates for Microcatheters
Radiology, 1977Microcatheters are defined as those with outer diameters of 4 French gauge or less. Authors tested five sizes of catheters from 2 to 4 French, inclusive to determine the bursting and maximum safe flow rates with automatic injectors. This communication describes the maximum flow rates for various sizes and lenghts, as well as the feasibility of ...

Urinary flow rates in hypospadias
British Journal of Plastic Surgery, 1997Uroflowmetry has been performed on 140 occasions in 90 patients with hypospadias before and after reconstructive surgery. Children with hypospadias tend to have a lower maximum urinary flow rate for volume voided than the general population, lying around the population 5th centile.

Glycosaminoglycans and Urine Flow Rate
Nephron, 2008The value of glycosaminoglycans determination in urine has been challenged because the relation between the glycosaminoglycans concentration and other signs of kidney damage is a matter of controversy. It is quite possible that the observed discrepancies could be due to the influence of the urine flow rate, the urine concentration and the time of day ...

The flow rates of the 18- to 24-gauge catheters most commonly used in pediatrics were studied to determine which catheters and infusion techniques allowed for rapid volume replacement in infants and children. As expected, short, large-diameter catheters were found to have a higher flow rate, and flows under pressure in the largest catheters tested were

Measurement of urinary flow rate
Urology, 1983The various methods for measuring urinary flow rate from the first attempt by Rehfisch in 1897 to current techniques are described. The benefits or deficiencies of each method are considered, and it is concluded that while some of the more technically sophisticated pieces of equipment are necessary for the accurate determination of flow rates in the ...

From the Force Vital Capacity tracing obtained in 174 healthy school boys between 7 and 16 years of age, the flow over the initial 500 ml. (M.E.F.R. 1–700), middle half (M.M.F.) and third arter (E.F.R. 50–75) were calculated. data were statistically analysed and results compared with Western data.
