1. A device for measuring a glucose concentration in a host, the device comprising:

  • a sensor operably connected to an electronic circuit and configured to continuously measure a signal indicative of a glucose concentration in a host for a period of time; and

    a membrane located over at least a portion of the sensor, the membrane comprising a layer configured to control a flux of oxygen and glucose;

    wherein the device is capable of exhibiting, at a glucose concentration of 400 mg/dL, no more than a 10% drop in sensor output over a range of pO2 from 150 mm Hg down to 30 mm Hg, and wherein the device is configured to use an in vitro calibration factor for initial calibration.
