Noninvasive blood pressure measurements with single and twin‐hose systems—do mixtures matter?

Summary Noninvasive blood pressure monitors which use twin‐ and single‐hose cuffs complicate the movement of patients between bed spaces with different cuff‐hose systems. We assessed, using a commercially available noninvasive blood pressure monitor function analyser, the use of single‐hose cuffs coupled via a Y‐piece adaptor to the twin‐hose of noninvasive monitors designed for use with twin‐hose cuffs. Assessments were made at three simulated pressures (200/150 mmHg, 120/80 mmHg, and 60/30 mmHg) and at normal and weak arterial pulsations. The use of a single‐hose cuff attached with the Y‐piece adaptor did not adversely affect the performance of the monitors.
