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.
