(a) The concentration-dependent change in the optical density at 430 nm upon WST-1 oxidation by CS exposure with different dilution flow rates of 0.1-3.0 0.1-3.07-69% CS).
Our purpose was to evaluate the use of a more concentrated bicarbonate replacement fluid in order to customize the buffers supply in individual patients, through the modulation of the post-dilution flow rate according to their acid-base status.
The input fields were as follows: Qb (ml/minute), citrate solution concentration (mmol/l), citrate solution flow rate (l/hour), bicarbonate and ionized calcium replacement solution concentration (mmol/l), post-dilution flow rate (l/hour), patient's bicarbonate and ionized calcium (mmol/l), patient's hematocrit and serum protein (g/dl), net ultrafiltration rate (l/hour).
Input fields: blood flow rate (ml/min), citrate solution concentration (mmol/l), citrate solution flow rate (l/h), bicarbonate and ionized calcium dialysate and/or replacement solution concentration (mmol/l), dialysate flow rate (l/h), post-dilution flow rate (l/h), patient's bicarbonate and ionized calcium (mmol/l), patient's hematocrit and serum protein (g/dl), net ultrafiltration rate (l/h).
Post-dilution flow rate (Prismasol 2 for protocol A, Phoxilium for protocol B) was adjusted to achieve a prescribed dialysis dose, corrected for pre-dilution [correction factor = blood flow rate/ blood flow rate + Pre-dilution infusion rate)], of at least 25 ml/kg/h.
Filtration may be efficient, but with a high sample dilution, low flow rate and optimized geometry.
This problem cannot be easily overcome by an increase of pre-dilution citrate flow rate, which invariably results in a significant increase of effluent rate with the consequent loss of more citrate and bicarbonate in the ultrafiltrate.
As a consequence, despite optimization of CVVH parameters (that is, citrate infusion rate and/or post-dilution bicarbonate flow rate) the persistence of a mild metabolic acidosis required additional bicarbonate infusion.
This paper also presents an application of the dilution method to flow rate measurement of an industrial outfall and the uncertainty analysis associated with the obtained values.
Oxygenates are optimized at C6H14/O2≈2.5 and are favored by low preheat temperature, some dilution, and intermediate flow rate (catalyst contact time).
It is shown that soft plasma conditions such as high pressure, low dilution, high toluene flow rate, low power, and low temperature were necessary to incorporate phenyl rings in the film.
