The Effect of Changing Arterial Transducer Position on Stroke Volume Measurements Using FloTrac System Version 4.0: A Pilot Experimental Study.

ABSTRACT:

Objectives

We conducted a pilot study using an experimental study protocol to evaluate the measurement error of arterial pulse contour analysis-derived stroke volume due to improper transducer leveling during the passive leg raising test and the impact of such error on the determination of fluid responsiveness.

Design

Prospective observational study.

Setting

A medical-surgical ICU at a tertiary referral center in Kobe, Japan.

Patients

Consecutive critically ill adult patients using the FloTrac system Version 4.0 (Edwards Lifesciences, Irvine, CA) for hemodynamic monitoring between September 1, 2018, and November 31, 2018.

Interventions

None.

Measurements and main results

Using 20 patients, we estimated the change in the zero-reference level of an
