Investigational products
The test products for both studies were provided by Medtronic (Boulder, CO). Both devices are pulse oximetry sensors that are very similar in design, consisting of an optical region that houses the sensor and an associated fabric tail, as shown in Figure Image of optical (outlined in orange) and tail (outlined in blue) regions on the OxySoftN sensor. OxySoftN uses a silicone‐based skin‐contacting adhesive.
