Not illustrated. 1914 edition. Excerpt: ...Qxp On this hypothesis it is possible to institute a direct experimental test as to whether the amount of oxygen which left the capillary varied directly with the pressure of oxygen in the capillary. The amount of oxygen can of course be directly measured from a knowledge of the oxygen in the blood going to and leaving the organ in question, and of the quantity of blood which goes through it in a given time. The measurement of p offers a much more diflicult problem. Theoretically Verzar should in each experiment have gone through the whole gamut of determinations we have set forth in the example given above. In practice we had to approximate. A first approximation to the capillary oxygen pressure will be arrived at by an application of the percentage saturation of the arterial and venous blood to the dissociation curve of the arterial blood of an animal of the same species. The measurement of Q involves the amount of oxygen in the blood: if the oxygen capacity be also known the percentage saturation is arrived at. We can, then, determine the percentage saturation of the arterial and venous bloods and, by laying them off on the dissociation curve, we can determine the pressure of oxygen in the artery and the vein, and in that way at least ascertain within limits the pressure in the capillary at a given time. We need scarcely interrupt the course of our discussion to point out to the reader the extreme fallibility of the methods in which we are engaged. We are in the position of one navigating a diflicult channel in foggy weather. Nevertheless, it may be that the points which we _ have to observe are sufliciently obvious to stand out even in the fog, that in short there are fixed laws determining the pressure in the tissues which can be...
