Brief summary

The purpose of this study is to compare the hemoglobin results obtained with 1) the HemoCue™, 2) the Masimo SpHb™, and 3) the UCSF Clinical Laboratory. The goal is to determine if these three values differ from each other during various levels of blood loss in the clinical care of patients for spine revision and hip revision surgery.

Design outcomes

Primary

Measure	Time frame	Description
See description below	A minimum of three differences recorded during surgery	Primary outcome is based on the difference between SpHb (Masimo SpHb™ continuous hemoglobin reading ) - tHb (laboratory hemoglobin determination).

Secondary

Measure	Time frame	Description
See description below	A minimum of three differences recorded during surgery	Secondary outcome is based on the difference between a HemoCue™ derived hemoglobin determination - laboratory hemoglobin determination.
