In normal oxygenation conditions, the culture medium corresponded to one-tenth of the volume of the culture vial volume, and one-half for reduced oxygenation conditions.
Reduced oxygenation causes dynamic reorganisation of the actin cytoskeleton resulting in changes of cell contractility, shape and motility [ 27] thereby providing important information on cell state and activation.
In the present study we have used flow cytometric DNA measurements on synchronised human NHIK 3025 cells to measure cell cycle progression under various conditions of reduced oxygenation.
In this study we compared PEEP optimization performed by FOT with the one based on oxygenation data as suggested by the ARDSNet.
The most common form of fMRI uses standard clinical magnetic resonance imaging scanners to create images based on blood oxygenation level-dependent (BOLD) contrast.
Current practice is largely based on optimal oxygenation being unknown and instead adopts the assumption that maximal oxygenation is of maximal benefit [ 1, 2].
In the derivation cohort, a model based on age, oxygenation index on day 3, and cardiovascular failure on day 3 predicted death and/or ventilator dependence.
When PEEP was set to the value that maximized the reactance, higher PEEP levels, improved lung mechanics, and better oxygenation were observed compared with those measured when PEEP was set following standard clinical protocols based on oxygenation (ARDSNet).
Progression through each ACA phase occurred based on assessments of oxygenation, air exchange, wheezing, accessory muscle use, and respiratory rate performed at prescribed intervals.
Thus, NIRS measures cortical activation based on oxygenation of hemoglobin, similar to the fMRI BOLD response.
