Noninvasive hemoglobin monitoring: how accurate is enough?
Evaluating the accuracy of medical devices has traditionally been a blend of statistical analyses, at times without contextualizing the clinical application. There have been a number of recent publications on the accuracy of a continuous noninvasive hemoglobin measurement device, the Masimo Radical-7 Pulse Co-oximeter, focusing on the traditional statistical metrics of bias and precision. In th...
متن کاملComparison of the accuracy of noninvasive hemoglobin monitoring by spectrophotometry (SpHb) and HemoCue® with automated laboratory hemoglobin measurement.
BACKGROUND The reference method for hemoglobin concentration measurement remains automated analysis in the laboratory. Although point-of-care devices such as the HemoCue® 201+ (HemoCue, Ängelholm, Sweden) provide immediate hemoglobin values, a noninvasive, spectrophotometry-based technology (Radical-7®; Masimo Corp., Irvine, CA) that provides continuous online hemoglobin (SpHb) measurements has...
متن کاملNoninvasive monitoring of hemoglobin. The effects of WBC counts on measurement.
The efficacy of a noninvasive hemoglobin monitoring device (Astrin, Sysmex, Kobe, Japan) was evaluated for healthy volunteers and for patients with hematologic disorders. At the same time, the effects of WBC counts on noninvasive monitoring were studied by clinical evaluation and in ex vivo experiments. The hemoglobin levels determined by the device (Ast-Hb) and a conventional analyzer (T-Hb) w...
متن کاملEvaluation of Electrical and Optical Plethysmography Sensors for Noninvasive Monitoring of Hemoglobin Concentration
Completely noninvasive monitoring of hemoglobin concentration has not yet been fully realized in the clinical setting. This study investigates the viability of measuring hemoglobin concentration noninvasively by evaluating the performance of two types of sensor using a tissue phantom perfused with a blood substitute. An electrical sensor designed to measure blood volume changes during the cardi...
متن کاملTransforming hemoglobin measurement in trauma patients: noninvasive spot check hemoglobin.
BACKGROUND Technological advances now allow for noninvasive Hbg measurements. Previous studies have reported on the efficacy of continuous noninvasive Hgb devices. Recently, a new device, Pronto-7, a spot check pulse CO-oximeter has become available. The aim of our study was to assess noninvasive Hgb measurement in trauma patients. METHODS We performed a prospective cohort analysis of all tra...
