Oxygen delivery to tissues

    https://erj.ersjournals.com/content/erj/4/10/1258.full.pdf
    Tissue hypoxia occurs when cellular oxygen delivery does not fulfill cellular oxy­ gen demand. Cellular oxygen delivery involves a co-ordinated sequence of pulmonary oxygen transfer, convection of blood to tissue, and diffusion of oxy­ gen from capillary to cell.Author: R. W. Samsel, P. T. Schumacker

Oxygen delivery to tissues.

    https://www.ncbi.nlm.nih.gov/pubmed/1804674
    Tissue hypoxia supervenes when tissue oxygen tension (PO2) falls below a critical point, and the point where this occurs can be predicted from the systemic oxygen delivery or extraction ratio. A growing body of evidence suggest that tissue oxygen extraction may be impaired in adult respiratory distress syndrome (ARDS) and sepsis.Author: R. W. Samsel, P. T. Schumacker

    Aug 01, 2004 · Oxygen is carried in arterial blood dissolved in solution (<2% when breathing air) and combined with haemoglobin (>98% in air). Tissue hypoxia is a deficiency of oxygen at the tissue level; it may be caused by increased demand, decreased supply or abnormal cellular utilization.Author: S. A. McLellan, T. S. Walsh

Heterogeneity of oxygen delivery impairs oxygen extraction ...

    The hypothesis that the distribution of oxygen demand in relation to oxygen supply (dO2/qO2) effects oxygen extraction in peripheral tissues was tested. By using a simple theoretical model, realistic biphasic oxygen consumption-delivery relationships were predicted from dO2/qO2 distributions.Author: K. R. Walley

Multiple Causes of Low Oxygen (Hypoxia)

    https://drsircus.com/oxygen/multiple-causes-of-low-oxygen-hypoxia/
    Aug 16, 2018 · Tissue hypoxia, as a result of cardiopulmonary dysfunction or reduced oxygen-carrying capacity, is a frequently encountered clinical problem. high altitude; anemia: Red blood cells transport oxygen from the lungs to the body organs and tissues via a carrier molecule called hemoglobin. A deficiency of red blood cells, or anemia, limits the oxygen-carrying capacity of the blood, potentially leading to reduced total oxygen …

ABC of oxygen: Oxygen transport—2. Tissue hypoxia

    https://www.ncbi.nlm.nih.gov/pmc/articles/PMC1114253/
    Nov 14, 1998 · Mathematical models of tissue hypoxia show that the fall in cellular oxygen resulting from an increase in intercapillary distance is more severe if delivery of oxygen to tissues is reduced because of “hypoxic” hypoxia (a fall in Pao 2 ) rather than “stagnant” (a fall in flow) or “anaemic” (reduced haemoglobin) hypoxia.Author: R M Leach, D F Treacher
