Excerpt from The Clinical Study of Blood-Pressure: A Guide to the Use of the Sphygmomanometer in Medical, Surgical, and Obstetrical Practice, With a Summary of the Experimental and Clinical Facts Relating to the Blood-Pressure in Health and in Disease

The modern physician's armamentarium is so complex that additions to it are far from an unmixed boon. Nevertheless, the sphygmomanometer has been welcomed in many quarters as an instrument of real value. Two questions, however, must be fairly and squarely answered, before its general use can be advocated; First, Does it yield accurate information, which can be had in no easier way? Second, Is this information worth the time expended in obtaining it?

The answer to the first question is simple. Five minutes' trial will convince the most sceptical that his previous judgments, based on his supposedly trained sense of touch, were often fallacious. High tension was certainly recognized before the introduction of the sphygmomanometer, but so was fever before the days of clinical thermometers. No physician would endorse the sentiments of the old colored mammy, who said, "What you want wif dese new-fangle fermometers, honey? I puts de babies in de baf, and if de water's too cole it turns 'em blue, if it's too hot it turns 'em red." In medicine, accuracy of observation is the first step toward a correct diagnosis, without which nothing but bald empiricism is possible.

The second query cannot have so prompt a reply. The value of a knowledge of the actual blood-pressure in a particular case must depend largely on the observer's acquaintance with the physiological and pathological causes for variation.
