Outcome Measures

Primary Outcomes (1)

  • Comparison of Masimo Rainbow technology to arterial blood samples taken during surgery

    Correlation between standard, lab-based, hemoglobin measurement and concurrent SpHb.

    Five year

Interventions

In addition to the standard pulse oximeter used for clinical care, up to six SpHb finger sensors will be applied to the patient. Additional sensors may also be applied to the forehead, neck, chest and ears. Masimo FDA cleared pulse CO-Oximeter devices: Radical-7, Rad-87, Rad-57, Pronto, Pronto-7, for the noninvasive measurement of SpO2, PR, PI, PVI, SpCO, SpMet, and SpHb, total hemoglobin and respiratory rate. No treatment decisions will be made based on the new technology and no extra medical procedures are required for the study.

4mL arterial blood samples (up to 1 per hour), outside standard of care, are drawn throughout the surgical procedure and sent to UCDMC lab/Masimo lab for analysis.
