Multi-Gas Anesthetic Analyzer

Principle of Operation: The measurement of CO2, N2O, and
anesthetic agents in gas mixtures is based on the fact that
different gas components absorb infrared light at specific
wavelengths. A beam of infrared light is directed through the gas
flow in the anesthesia sensor adapter. As the beam passes through
the adapter, some of the light is absorbed by the gas mixture. The
amount of absorbed light is measured by a miniaturized spectrometer
which incorporates multiple light filters and an infrared detector
that converts the light beam to an electrical signal and then a
digital value. The ratio of light measured through the filters is
used to calculate the gas concentration.

Available Measurements

Multi-Gas Anesthetic Analyzer
The anesthesia sensor is a mainstream gas analyzer that works in conjunction with the TSI® CertifierTM Plus or CertifierTM Pro test systems to measure real-time gas concentrations of CO2, N2O, and anesthetic agents Halothane, Enflurane, Isoflurane, Sevoflurane, and Desflurane.
Principle of Operation
The measurement of CO2, N2O, and anesthetic agents in gas mixtures is based on the fact that different gas components absorb infrared light at specific wavelengths. A beam of infrared light is directed through the gas flow in the anesthesia sensor adapter. As the beam passes through the adapter, some of the light is absorbed by the gas mixture.
The amount of absorbed light is measured by a miniaturized spectrometer which incorporates multiple light filters and an infrared detector that converts the light beam to an electrical signal and then a digital value. The ratio of light measured through the filters is used to calculate the gas concentration.

Connecting the Anesthesia Sensor
The anesthesia sensor is connected to the USB-A port of the CertifierTM flow analyzer which provides power and user control from its instrument display.
An airway adapter is inserted into the sensor module which can then connect to the test circuit. There are two types of airway adapters that can be used with the anesthesia sensor: adult/pediatric and infant.
Follow the steps below to setup the anesthesia sensor:
1. Attach an airway adapter to the anesthesia sensor. The adapter will click when properly seated.

2. Connect the anesthesia sensor cable to either USB-A port on the CertifierTM flow analyzer using the supplied DB-9 serial to USB converter.
3. Power on the CertifierTM instrument and configure the anesthesia sensor measurements.
4. Wait a minimum of 30 seconds then perform the zeroing procedure.
5. The green status LED on the anesthesia sensor illuminates when the sensor is ready for use.
6. Connect the attached airway adapter to the anesthesia test circuit.
7. Position the anesthesia sensor with the status LED pointing upwards.

CAUTION
· DO NOT run anesthetic agents through CertifierTM flow modules/channels.
Use of the anesthesia sensor with CertifierTM Flow Analyzers is for testing purposes only and should not be used for human measurements.
Touchscreen Operation
Once the anesthesia sensor is connected to the CertifierTM flow analyzer, a module card will be generated at the top of the dashboard for the connected sensor.
Module Card
The module card will display the model number of the connected sensor (IRMA AX+) and the anesthetic agent detected by the anesthesia sensor. If no anesthetic agent is detected, the module card will display “No Agent.”
Press the IRMA AX+ module card to view and edit settings for the anesthesia sensor.

Zeroing the Anesthesia Sensor
Zeroing should be performed every time the airway adapter is replaced, or whenever an offset in gas values or an unspecified gas accuracy message is displayed.
Before proceeding with the zeroing procedure, allow 30 seconds for warm up after powering on the anesthesia sensor or after changing the adapter. The green LED on the sensor will be blinking for approximately 5 seconds while zeroing is in process.
Zeroing Procedure
Zeroing is performed by snapping a new airway adapter on the anesthesia sensor without connecting to the test circuit and then using the CertifierTM flow analyzer to transmit a zero reference command to the anesthesia sensor.
NOTICE The presence of ambient air (0% CO2) in the airway adapter is of crucial importance for a successful zeroing. No span zeroing is required.
Press the flow module card for the anesthesia sensor.
On the anesthesia sensor module card, select the ZERO button.
