An evaluation of the BD RT2000 reusable transducer system for invasive blood pressure monitoring

Abstract

The static accuracy and zero offset meet the Association for the Advancement of Medical Instrumentation (AAMI) BP22:1994 standard. The zero drift is judged to be acceptable for arterial pressure measurement because a change of 3 mmHg is not clinically significant. The 15% bandwidth is judged to be adequate for fluid-filled pressure monitoring systems. It will be advantageous to couple the disposable dome to the reusable transducer when the disposable dome has a positive pressure.

Falsely low arterial blood pressure due to pressure transducer damage in three horses

“…Any air bubbles in the line will also increase damping because of the difference in density to water (step 6) 10 11. These potential errors have been described in the literature for both reusable and disposable blood pressure systems 16 18 19. In the case series, those reasons for damping were excluded and therefore at the end of the first case the blood pressure system was dismantled to check there was not any faulty equipment.…”
