Several deviations from normal standards have been noted in the cardiovascular functions of schizophrenic patients.1 The venous blood pressure seems to have received little attention. It was decided, therefore, to determine whether there are any differences between the venous blood pressure of schizophrenic patients and that of normal persons and whether peripheral cyanosis bears any detectable relationship to the level of the venous blood pressure.
As regards normal subjects, Moritz and von Tabora,2 Blumgart3 and Taylor and his associates4 reported 10 cm. of water as the upper limit; Villaret and his colleagues5 placed the upper limit at 13 cm., while Bedford and Wright6 found that forty-one of forty-seven values for normal subjects ranged between 5 and 15 cm. of water. Rothman7 stated that the normal venous blood pressure is between 4 and 6 cm., while Brown8 found from 3 to 9 cm.
