Utility of gas inlet pressure monitoring in extracorporeal membrane oxygenation.

Purpose: Purpose: Condensation that clogs the hollow fibers of the oxygenation and accumulation of plasma leaks reduces oxygenated lung capacity. In this study, artificial We evaluated whether monitoring changes in lung gas inlet pressure was a way to predict these complications.

Methods: Changes in gas inlet pressure and oxygenation capacity of three different prostheses (BIOCUBE6000, EXCELUNG PRIME, and Capiox-LX) Evaluated the relationship.

Real-Time Measurement of Polyvinylpyrrolidone Eluted from Polysulfone Membrane Dialyzers Based on the Ultraviolet Spectrum.

The objective of this study was to develop a new method for measuring polyvinylpyrrolidone (PVP) eluted from polysulfone (PSu) membrane dialyzers. The Müller method is generally used for the measurement of PVP, in which the PVP concentration is determined by measuring the absorbance after a red color is generated by the formation of PVP-iodine complexes when iodine is added to a sample. In contrast, our method does not require any reagents and allows real-time measurement of PVP by the ultraviolet absorption spectrum (UV-s method).

Influence of Sterilization and Storage Period on Elution of Polyvinylpyrrolidone from Wet-Type Polysulfone Membrane Dialyzers.

The objectives of this study were to investigate the influence of the sterilization and storage period on elution of polyvinylpyrrolidone (PVP) from wet-type polysulfone (PSu) membrane dialyzers. APS-15SA (APS) dialyzers sterilized by gamma-radiation and RENAK PS-1.6 (RENAK) dialyzers sterilized by autoclaving were compared in this study.
