Brief summary
Evaluation of the noninvasive oxygen saturation (SpO2) performance of the noninvasive Masimo MightySat against reference arterial blood samples analyzed by a laboratory CO-oximeter reference instrument. The study will include different subgroups to assess the performance across different genders and skin pigmentation.
