Gas or Vapor Level

(Balance: Mixture of 30% O2 / 70% N2O, except where noted)

Gas or Vapor	Test Level	Oxygen Reading
		Error
Helium	50%, balance O2	0%
Nitrous Oxide	80%, balance O2	0%
Carbon Dioxide	10%, balance O2	0%
Halothane	4%	< 1.5% O2 *
Enflurane	5%	< 1.5% O2 *
Isoflurane	5%	< 1.5% O2 *
Sevoflurane	5%	< 1.5% O2 *
Desflurane	15%	< 1.5% O2 *

*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 AX300-I SHOULD NOT BE USED IN THE PRESENCE OF FLAMMABLE ANESTHETICS SUCH AS DIETHYL ETHER OR CYCLOPROPANE.

CAUTION: THE AX300-I, OXYGEN SENSOR AND ASSOCIATED HARDWARE ARE NON-STERILE DEVICES. DO NOT AUTOCLAVE THE INSTRUMENT OR SENSOR, AS THIS WILL DAMAGE THE EQUIPMENT.

2.3.5.2CARE AFTER USE IN NITROUS OXIDE

CAUTION: THE R17MED 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, when using the tee, remove the plastic flow diverter and leave the sensor in room air. If the
