Evaluation of filtering methods for acquiring radial intra-artery blood pressure waveforms.

The methods for evaluating noninvasive blood pressure (NIBP) monitors using an intra-arterial reference are detailed in the ANSI/AAMI/ISO 81060-2:2009 standard. In a recent study, GE Healthcare obtained invasive radial arterial blood pressure waveforms. The work presented here describes the development of filtering strategies for obtaining high fidelity intra-arterial pressure waveforms for NIBP accuracy testing using the 81060-2 standard.

Validation of a conical cuff on the forearm for estimating radial artery blood pressure.

Introduction: There has been a growing need for and interest in measuring noninvasive blood pressure (NIBP) in obese patients. In many situations, available rectangular upper arm blood pressure cuffs do not fit properly, closing in a crisscross manner or overlapping the elbow. To address this issue, GE Healthcare has designed a conically shaped cuff for use on the forearm to estimate radial arterial blood pressure.
