The relation between the blood pressure and the peripheral flow of blood is of interest in view of certain recent opinions on the mechanism of surgical shock (Freeman,¹ Meek,² Roome³). It has been suggested, and supported to various extents, by these authors that shock arises by the following mechanism: A marked reduction of the peripheral flow occurs as the result of a diminished blood volume and/or sympathicoadrenal activity; this ischemia produces capillary injury, with increased permeability, permitting a generalized loss of blood plasma, which finally progresses to peripheral circulatory failure.

Poiseuille and others⁴ have exhaustively studied the relation existing between the head of pressure (P) and the volume flow (F) of homogeneous fluids in small rigid tubes. Under these conditions F is proportional to P, the ratio P/F is a constant and the relation is graphically linear. These observations, however, cannot be directly applied to the . . .
