Claim Text:
1. An apparatus for facilitating blood pressure measurement, including a fluid reservoir arranged to be connected in fluid communication with a blood pressure arm cuff, the fluid reservoir providing an additional fluid volume to the fluid volume of the cuff during measurement of blood pressure of a patient, and wherein the fluid reservoir has a compliance such that the fluid reservoir is arranged to change volume when a change of pressure is applied, adding little or no pressure back into the system comprising the fluid reservoir and the blood pressure cuff, when the fluid reservoir changes volume, and the fluid reservoir being operable during deflation of the blood pressure cuff to slow the rate of change in pressure, and wherein the compliance is arranged such that oscillations of pressure from the blood pressure cuff are not damped by the fluid reservoir, wherein the fluid reservoir is arranged to expand as the blood pressure cuff is inflated to increase the potential volume by 25 mls to 40 mls over an operating range of 60 mm Hg to 180 mm Hg, and the apparatus further including a controller that controls measurement of blood pressure in a deflation mode.
