For a sphygmomanometric method of indirect blood-pressure measurement to be accurate, the cuff must operate so that the intrabladder pressure is always the same as the pressure applied by the tissues of the arm to the artery wall. To determine under what conditions this occurs, analyses are presented assuming the arm to be a rotationary symmetric incompressible solid cylinder acted upon by various cuff pressure fields. The results indicate that the pressure applied to the artery wall is markedly influenced by longitudinal motion of the arm tissue, which must be constrained to have an accurate pressure transmission. It is shown that an optimal cuff size does effectively accomplish this under its central region. On the basis of these analyses, design criteria for a blood pressure cuff have been established.
