* Errors are approximate and may vary based on exposure times and concentrations.
These performances meet or exceed the requirements of ISO 7767: 1997 (E).
CAUTION: The TED 200-T should not be used in the presence of flam-
mable anesthetics such as diethyl ether or cyclopropane.

2.2.2.2 Care after use in nitrous oxide

CAUTION: The T-7 sensor should not be left in nitrous oxide mixtures
any longer than absolutely necessary.
After exposure to nitrous oxide mixtures, the sensor should be left in 100% oxygen
overnight (e.g., left in a breathing circuit that has been flushed with pure oxygen). If this
is not practical, the plastic flow diverter should be removed and the sensor left in room
air. If the oxygen reading continues to drop after each use in nitrous oxide the sensor
should be removed from service. If the sensor can no longer be calibrated or if there is
any sign of electrolyte leakage, the sensor should be disposed of in accordance with
local regulations and the Material Safety Data Sheet (MSDS) located in Chapter 4.0:
Appendices.

2.2.3 Sterilization

The T-7 sensor and interconnecting cable may be gas sterilized using low tempera-
ture ethylene oxide. A vacuum must not be drawn on the sensor during the sterilization
process.
The TED 200-T itself cannot be liquid sterilized or autoclaved. The surface of the
case may be wiped with isopropyl alcohol and allowed to air dry. In extreme cases, a
mild detergent may be used.
