Well known in clinical settings for its line of noninvasive patient monitoring equipment, Masimo, Incorporated offers the $145 iSp02 tablet-driven pulse oximeter. Intended for extreme sports and aviation use, the iSp02 measures blood oxygenation, pulse rate and perfusion index, and presents the data in a free tablet app that’s compatible with iOS and Android.
The finger sensor attaches to a 30-inch cable that plugs into the tablet—an obvious drawback for extreme sports and cockpit use, in our view, compared with the new Nonin Bluetooth NoninConnect portable. The interface cable is barely long enough to reach a tablet that’s placed on the copilot seat. For panel-mounted tablets that sit in an AirGizmos dock mount, the device is nearly unusable without creative wire routing.
