    Jun 05, 2001 · Thereto, we examined human brain oxygen transport by using a more general model of oxygen delivery and diffusion (16, 17). This approach, used by Hudetz ( 18 ) to examine oxygen delivery in rat brain, makes no assumptions regarding oxygen content or whether oxygen diffusion out of the capillary is bidirectional.Author: Mark A. Mintun, Brian N. Lundstrom, Abraham Z. Snyder, Andrei G. Vlassenko, Gordon L. Shulman, Marcu...

    the assumption that oxygen content in the brain tissue is negligible was critical to the conclusion that CBF and CMRO2 are tightly coupled. Thereto, we examined human brain oxygen transport by using a more general model of oxygen delivery and diffusion (16, 17). This approach, used by Hudetz (18) toAuthor: Mark A. Mintun, Brian N.

    Matthew A. Rainaldi MD, Jeffrey M. Perlman MBChB, in Assisted Ventilation of the Neonate (Sixth Edition), 2017. Oxygen and Brain Injury. Fraction of inspired oxygen (FiO 2) is a parameter that must be chosen by the provider when respiratory support is initiated—this may range from room air to 100% O 2.Clinicians often use oxygen saturation (SpO 2) and PaO 2 to subsequently guide their ...

The physics of functional magnetic resonance imaging (fMRI)

    https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4376284/
    Functional magnetic resonance imaging (fMRI) is a methodology for detecting dynamic patterns of activity in the working human brain. Although the initial discoveries that led to fMRI are only about 20 years old, this new field has revolutionized the study of brain function.Author: Richard B Buxton

    Aug 01, 2004 · Increased oxygen extraction by the tissues occurs during anaemia by improved matching of oxygen delivery to oxygen demand. There is a redistribution of blood flow to areas of high demand, such as the myocardium and the brain. In the microcirculation a number of mechanisms help to maintain tissue oxygenation.Author: S. A. McLellan, T. S. Walsh

DO2 Equation – Peripheral Brain

    https://pbrainmd.wordpress.com/2016/01/21/do2-equation/
    Jan 21, 2016 · The human body does not care much about pO2 or FiO2. What is important to the body is the amount of oxygen actually being delivered to the tissues. Focusing on the pO2 in the ABG results, or the FiO2 settings of O2 support, without understanding how oxygen is delivered to body tissues can have dire consequences. The formula…
