Oxygen is known to play a key role in cellular energetics. Both oxidation and other forms of
energy production depend on a continuous supply of oxygen to the cells. In mammals …

A compartmental model is formulated for oxygen transport in the cerebrovascular bed of the
brain. The model considers the arteriolar, capillary and venular vessels. The vascular bed is …

The classical view of oxygen (O 2) uptake in pulmonary capillaries assumes implicitly that
capillary blood can be regarded as a continuous homogeneous hemoglobin solution. In this …

The impacts of the particulate nature of blood upon capillary O 2 release have been studied
extensively by Federspiel and Sarelius [8] and by Federspiel and Popel [9]. The latter …

Tissue oxygenation in the proximity of single capillaries was investigated mathematically,
with the red blood cells (RBC) modeled as discrete oxygen sources separated by plasma …

Anesthetized mechanically ventilated rabbits were subjected to progressive hypoxemia (n=
7) to determine the relationship of venous PO2 (PvO2) to skeletal muscle PO2 (PtiO2) …

Calculations indicate that the PO2 in plasma falls to zero approximately 3 microns from an
erythrocyte at O2 consumption (VO2) characteristic of myocardium (Federspiel, WA, and A …

Is venous PO 2 an index of tissue PO 2, of end capillary PO 2, or neither of these because of
diffusive shunting from arterioles to venules? To evaluate diffusive shunting and venous PO …

Abstract Characteristic of a Krogh (1919, 1929) analysis is a polygonal array of cells with
oxygen supplied by capillaries at each cell vertex. Because of the symmetry of the …

The process of gas exchange in systemic capillaries and its surrounding tissue is simulated
numerically in a hyperbaric environment, taking into account the molecular diffusion …
