4 Certifier™ Anesthesia Sensor Kit Model 4093
Multi-Gas Anesthetic Analyzer
The anesthesia sensor is a mainstream gas analyzer that works in
conjunction with the TSI®Certifier™Plus or Certifier™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.
Available Measurements
Symbol
Description
AA1
Anesthetic agent as a percentage of concentration (if
detected, that specific agent will be displayed).
CO2
Concentration of carbon dioxide as a percentage.
N2O
Concentration of nitrous oxide as a percentage.
PATM
Atmospheric pressure displayed in units cmH2O, kPa, Pa,
hPa, mbar, mmHg, inH2O, or psi.
User Manual 5
Connecting the Anesthesia Sensor
The anesthesia sensor is connected to the USB-A port of the
Certifier™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 Certifier™flow analyzer using the supplied DB-9 serial to
USB converter.
3. Power on the Certifier™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.

C A U T I O N
•DO NOT run anesthetic agents through Certifier™flow
modules/channels.
▪Use of the anesthesia sensor with Certifier™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 Certifier™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.
User Manual 7
The manufacturer (Masimo®) and serial number (ex. 914990) of the
anesthesia sensor are displayed in the heading of the module card
dialog screen.
Three different levels of oxygen concentration can be selected based
on the oxygen percentage present in the gas flowing through the
anesthesia sensor.
If an anesthetic agent is detected, it will be displayed in this dialog
screen. “No Agent” will be displayed if the sensor does not detect an
anesthetic agent.
NOTICE
Anesthetic agents cannot be selected by the user but instead are
automatically detected by the anesthesia sensor.
Selecting Measurements
From the Parameter screen, access the measurement selection screen
by pressing on any of the currently displayed measurement symbols,
readings, or units of measurement, or by pressing the pencil icon in the
right navigation bar.
8 Certifier™ Anesthesia Sensor Kit Model 4093
Press the (+) ADD tile to select an additional measurement, or press
the measurement symbol of a currently selected measurement to
change that measurement parameter.
Once pressed, a list of available measurements will be displayed in
alphabetical order. If more than one module is connected, a letter (ex.
M, A, B) will indicate which module the measurement is coming from.
The letter “M” is used to indicate measurements coming from the
Masimo®anesthesia sensor module. Swipe up and down to scroll
through the list options then tap to select.
Press the orange Xbutton in the right navigation bar at any time
to disregard all changes and return to the Parameter screen.
Press the green checkmark button in the right navigation bar
to save changes and returns you to the Parameter screen.
User Manual 9
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 Certifier™ 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.
10 Certifier™ Anesthesia Sensor Kit Model 4093
Expose the anesthesia sensor to ambient air and press CONFIRM.
A dialog screen will appear while the anesthesia sensor goes through
the zeroing process. It takes approximately 5–10 seconds to zero the
anesthesia sensor.
A message will be displayed once the zeroing process has completed.
Press DONE to return to the previous screen.
