Sentence examples for oxygenation extraction from inspiring English sources

A point wise correlation was found, showing the proof of principle of using PCA based reconstruction for blood volume and oxygenation extraction.

We also demonstrate that PCA based reconstruction can indeed be used as a quantitative tool for blood volume and oxygenation extraction.

For this reason, the noise level of − ln [ R d (r, λ ) ] and its impacts on the performance of the Hb oxygenation extraction algorithm were evaluated.

To facilitate the identification and localization of a specific spectral feature in ε S a t O 2, a DWT technique was employed in the Hb oxygenation extraction algorithm.

We have shown previously [ 12, 37] that PCA applied to multi-spectral imaging data from the skin in the wavelength range between 750nm and 850nm can be used for blood volume and oxygenation extraction and mapping.

To demonstrate its clinical utility, the proposed Hb oxygenation extraction algorithm was applied to the diffuse reflectance spectra acquired from tissue phantoms and in vivo tissue, using a fiber-optic spectroscopy system.

Regional cerebral oxygenation and cerebral oxygen extraction were not different between groups immediately after the sustained inflation, or at any time during ventilation between groups (data not shown: p = 0.850 and 0.126 respectively).

However, a rise in lactate level may be delayed compared with markers of tissue oxygenation adequacy, such as oxygen extraction [ 16], and could be not sensitive enough to reflect tissue hypoperfusion [ 14].

Homogeneity of perfusion is more important than blood velocity in assuring tissue oxygenation, because cells are able to regulate oxygen extraction in the presence of variable flow.

Beyond the confirmation that ScvO2 of 70% is an important threshold for patient outcome, our study also suggests that, in septic patients, ScvO2 of 75% could be an even more relevant target that best ensures that overall tissue oxygenation is adequate in the context of septic oxygen extraction impairment.

In addition, the reduction in the coefficient of variation associated with the RBC velocity could have contributed an improvement of the tissue oxygenation because of the critical role of heterogeneity in oxygen extraction [25].
