MEASURING SYSTOLIC PRESSURE 81 Without care in The scale is not The connections All these defects readily broken, at least in my experience,packing, the mercury is apt to be spilled,easily read and the tube calibre is too smallare made with distensible rubber tubing,would be compensated for by its simphcity and compactness,but it possesses, hke its original model, the serious defect ofproviding much too narrow an armlet (see page 57). Its read-ings, therefore, tend to be too high in all adults, much too. Fig. 32.—Cxks spiiyomomakometer.(From Cook and Briggs.) high in stout ones. In children this does not enter into theconsideration, and the instrument was first used by Dr. Cookin a childrens hospital. For comparative readings on thesame patient the error will be constant and negligible, thus itmay be used in surgical operations and acute disease for fol-lowing variations in tension, but its results are not trustworthyfor diagnosis.
