Performance of the new SmartCardia wireless, wearable oximeter: a comparison with arterial SaO2 in healthy volunteers.

Background: Our goal was to evaluate the performance of a new wearable arm located pulse oximeter.

Methods: Twelve volunteers were monitored with three pulse oximeters and underwent desaturation to 70% SaO. We compared the accuracy of SpO reading from the SmartCardia system with SpO using two well established devices (Masimo and Nellcor) as reference.
