The impact of sensor application site on continuous noninvasive haemoglobin trends.

ABSTRACT:

Purpose

This prospective observational clinical study investigated discrepancy between noninvasive continuous haemoglobin (SpHb, Masimo Corp., Irvine, CA) measurements with sensors placed on three fingertips during elective cardiac surgery.

Materials and methods

The study included 12 adult patients who underwent elective coronary artery bypass grafting (CABG) under cardiopulmonary bypass (CPB). Three identical versions of SpHb sensors were placed on the fingers of the same hand and connected to dedicated Masimo Radical-7 monitors. Data were continuously recorded throughout the surgery. Multiple group comparison tests-Kruskal-Wallis and Alexander-Govern tests-were used to compare three sets of SpHb data (trends). Bland-Altman and Giavarina plots were used to compare the SpHb
