A blood pressure recorder
Summary: An instrument is described which has the following features: (1) an indirect method of measurement with a brachial cuff the only attachment to the subject; (2) fully automatic measurement and print-out system; (3) minimum discomfort in use; (4) compact, self-contained, and fully flameproof; (5) minimal loss of accuracy in peripherally vasoconstricted subjects; (6) rejection of patient movement artefact. The techniques used are considered in relation to other described systems. Clinical applications and future development are discussed. © 1968 John Sherratt and Son Ltd.
