Abstract: In blood pressure measurement of a vertebrate through use of an inflatable pressure cuff disposed about a limb of the vertebrate limb and inflated by pump driven by a motor, the air pressure within the cuff is determined at any given time during the inflation of the cuff by calculating the incremental change in pressure in the pressure cuff over a series of small time increments and summing the calculated incremental pressure changes from the initiation of cuff inflation to a desired point in time during the inflation of the pressure cuff. The incremental change in pressure within the cuff is calculated as a function of the incremental change in current drawn by the pump motor over the time increment.

Abstract: The diastolic blood pressure and a systolic blood pressure of a vertebrate are measured using an inflatable pressure cuff disposed about a limb of the vertebrate and connected to an inflation device through a single conduit. A pressure sensor is pneumatically connected to the cuff through the same common conduit. The sensed pressures at the diastolic and systolic points are corrected for a pressure differential associated with the flow of an inflation fluid through the common conduit. The sensed pressures at the diastolic point and the systolic point may be measured during inflation of the cuff or during controlled deflation of the cuff.

Abstract: A method is provided for blood pressure measurement by means of an inflatable cuff (50) applied to a limb of a vertebrate and pneumatically coupled to a first port (112A) and a second port (112B) of a blood pressure measurement apparatus (100). A pump (160) coupled to the second port inflates the cuff pneumatically. During an initial cuff inflation period, a first pressure sensor (180) pneumatically coupled to the first port senses a first pressure and a second pressure sensor (182) pneumatically coupled to the second port senses a second pressure. An analysis module (142) compares the magnitude of the first pressure to the magnitude of the second pressure to determine the relative relationship between the respective magnitudes of the first pressure and the second pressure.

Abstract: Adaptive attachments used in combination with a blood pressure cuff enable various blood pressure measurements to be taken in a hospital or other setting having various single and/or dual lumen manual or electronic blood pressure measuring equipment with a single patient-worn cuff.
