The present invention includes oximetry devices (12), open oxygen delivery system oximetry devices, and method for controlling oxygen saturation. According to one aspect of the present invention, an oximetry device includes an oxygen saturation sensor (16) adapted to couple with an individual, and configured to provide oxygen saturation information of the individual; an oxygen flow sensor (30) adapted to couple with an oxygen source (14), and configured to provide flow rate information of supplemental oxygen delivered to the individual; a controller (22) coupled with the oxygen saturation sensor, and adapted to control a flow valve (28) to control the flow rate of supplemental oxygen delivered to the individual responsive to the oxygen saturation information provided by the oxygen saturation sensor; and a memory device (46) coupled with the controller to store the oxygen saturation information, and flow rate information of supplemental oxygen. |
