1Push the sensor into the holder until it clicks into
position.
2Clamp the holder onto an IV pole, a shelf or
another appropriate location.
To remove the sensor from the holder, release the clip
and pull the sensor out of the holder.

Removing Exhaust Gases from the System

WARNING Anesthetics: When using the sidestream CO2 measurement on patients who are receiving or have
recently received anesthetics, connect the outlet to a scavenging system, or to the anesthesia machine/
ventilator, to avoid exposing medical staff to anesthetics.
Use an exhaust tube to remove the sample gas to a scavenging system. Attach it to the sidestream sensor
at the outlet connector.
Using the Mainstream CO2 Extension (M3016A)
The M3016A Measurement Server Extension measures partial pressure of carbon dioxide in a patient’s
expired gas using the mainstream method. When using the appropriate accessories you can use the
mainstream CO2 measurement with ventilated adults, pediatric and neonatal patients.
WARNING Infra-red radiation: Do not expose the airway adapter or M1460A transducer to infra-red radiation
during use. This may cause incorrect readings.
Preparing to Measure Mainstream CO2
1Attach the transducer connector to the CO2 connector on the measurement extension.
2Wait 20 minutes, allowing the transducer to reach its operating temperature and a stable thermal
condition.
3Perform an accuracy check and then, if necessary, calibrate the transducer.

Checking Transducer Accuracy

WARNING Check transducer accuracy at least once a week or if you doubt the CO2 readings.
1In Setup CO2 menu, select Cal. Mode to switch on calibration mode.
2Look at the calibration value displayed in the Setup CO2 menu next to Start Cal 1:. Is it
the same as the value on the calstick? If not, calibrate the transducer now.
3Place the transducer on the low cell of the calstick (labelled 0.0 mmHg or “ZERO”). The reading
on the screen should be zero within ±1 mmHg within one minute.
