Nov 22, 2019 · Mean oxygen consumption was 56 ± 8 ml/min/m 2, mean oxygen delivery was 281 ± 39 ml/min/m 2. Twenty-seven patients (42%) had an oxygen delivery lower than the previously mentioned critical value of 272 ml/min/m 2. None of the patients developed acute kidney injury according to …Author: Rik H. J. Hendrix, Yuri M. Ganushchak, Patrick W. Weerwind, Patrick W. Weerwind

Critical level of oxygen delivery in anesthetized man. Shibutani K, Komatsu T, Kubal K, Sanchala V, Kumar V, Bizzarri DV. Fifty-eight patients studied were anesthetized with diazepam, pancuronium, and a moderate dose of fentanyl; 99 sets of multiple hemodynamic variables were measured after sternotomy and before cardiopulmonary bypass.Author: Kinichi Shibutani, Toru Komatsu, Keshav Kubal, Vajubhai Sanchala, Vijaya Kumar, Dante V.

Introduction Low oxygen delivery during cardiopulmonary bypass is related to a range of adverse outcomes. Previous research specified certain critical oxygen delivery levels associated with acute kidney injury. However, a single universal critical oxygen delivery value is not sensible, as oxygen consumption has to be considered when determining critical delivery values. This study examined the ...Author: Rik H. J. Hendrix, Yuri M. Ganushchak, Patrick W. Weerwind, Patrick W. Weerwind

The C crit value determined for iron oxidation may be compared to the critical oxygen transfer rate in A. ferrooxidans cultures. Savić et al. (1998) and Veljković et al. (1999) reported that the maximum reaction rate constant for ferrous iron oxidation was not affected by oxygen transfer rate higher than approx. 1 mg O 2 l − 1 min − 1.Author: Martin Mandl, Eva Pakostova, Lenka Poskerova

Apr 09, 2019 · Oxygen extraction ratio (O2ER) is the ratio of oxygen consumption (VO2) to oxygen delivery (DO2) global oxygen delivery (DO2) is the total amount of oxygen delivered to the tissues per minute, irrespective of the distribution of blood flow; oxygen consumption (VO2) is the total amount of oxygen removed from the blood due to tissue oxidative ...

Tissue Oxygen Consumption & Tissue Carbon Dioxide Production. When cardiac output falls, so too does the delivery of oxygen [DO2] to tissue. Notably, as DO2 falls, the consumption of oxygen [VO2] by the tissues remains strikingly constant until a critical value of oxygen delivery [cDO2].
