BP-102

Overview

The BP-100/102 Intravascular Blood Pressure Transducer is a clinical blood

pressure transducer modified for use with digital recording equipment in research

applications. It consists of an active element and a separate (included) molded 5 ft.

extension cable. Although the elements are rugged and will stand up to repeated

use, they are not permanent. Replacement elements can be purchased directly

from iWorx Systems, Inc.

The BP-102 integrates a 3cc flush device and stopcock.

The sensor employed in this blood pressure (BP) transducer, and all disposable BP

transducers, is a strain gauge. The pressure output of the gauge is linear. This

makes transducer calibration very straightforward.

Page 2 Plug the DIN8 connector of the BP-100/102 into the DIN8 extension cable. 2) Attach the cannula from the subject's artery to either end of the BP-100 or to the 3-way stopcock on the BP-102. The cannula, stopcock, and transducer should be filled with heparinized saline solution to prevent clotting.
Page 3 50μV/mmHg x X400 gain = 20mV/mmHg Since the voltage applied to the transducer by any of these devices is 10V, the inverse of this factor can be used to convert the voltage output of the BP-100/102 to pressure: iWorx Systems, Inc.
