INTRODUCTION

The TED 191 Portable Oxygen Monitor is an easy-to-use, portable instrument that provides fast

and accurate oxygen monitoring and audio-visual alarm capability. The TED 191 is designed to

monitor concentrations of up to 100% oxygen in medical gas mixtures.

The TED 191 Portable Oxygen Monitor is designed and manufactured in accordance with strict

performance and quality protocols and subject to ISO 9002 Quality System protocols. When used

correctly, this instrument will provide you with many years of trouble free service.

The TED 191 Portable Oxygen Monitor is a compact, self-contained unit, which is battery powered

by four (4) dry cell batteries (size AA/penlight).

TELEDYNE ELECTRONIC TECHNOLOGIES

Analytical Instruments

APPLICATIONS

The instrument is designed for the measurement of oxygen concentrations in a variety of medical

gas mixtures. It is recommended that the instrument be used only as a secondary measuring

device to verify the concentration of oxygen in gas mixtures prepared using a gas blender or

similar apparatus. The use of this monitor as a primary or only means of preparing gas mixtures is

not advised.

The monitor is capable of verifying oxygen concentrations in gas mixtures used in:

•Anesthesia

•Neonatal Intensive care

•Adult Intensive care

•Respiratory / Oxygen Therapy

DESCRIPTION OF FUNCTIONAL ZONES

FRONT PANEL

On / Off Switch Allows the operator to turn the instrument on and off.

Alarm Mute Switch Allows the operator to “mute” the sound of the audible alarm

signal for ± 60 seconds. During this time, a red signal lamp will

flash, indicating a “muted” alarm condition is in force.

Calibration Control Allows the operator to calibrate the instrument to one primary set

point (usually 100%) in accordance with the designated calibration

protocol. This protocol is defined further in this manual and also.

Instructions in abbreviated form can be found on the top of the

monitor casing.

High Alarm Setting Allows the operator to define a high alarm threshold limit. Range

18% to 102% - if the actual measured value as displayed on the

LCD exceeds this set threshold, an audible and visual alarm

condition will be invoked.

Low alarm setting Knob Allows the operator to define a low alarm threshold limit. Range

18% to 100% - if the actual measured value as displayed on the

LCD falls below this set threshold, an audible and visual alarm

condition will be invoked.

Liquid Crystal Display Displays measured oxygen concentration, low battery condition

and provides a visual indication of either a high (+) or low (-) alarm

threshold violation.

OPERATIONS

1.2 INSTALLING THE BATTERIES

Withdraw the battery drawer from the monitor casing, by grasping the side lugs located on

either side of the battery drawer, and, firmly pinching them inwards, simultaneously pull the

drawer outwards. When new, this action can be somewhat stiff and difficult to execute. Care

should be taken not to damage either the drawer or the casing of the monitor when

executing this procedure.

Fresh batteries must be inserted into the four battery recepticles located within the battery

drawer assembly. Care should be taken to ensure that the correct battery polarity is

maintained.

Caution : Improper installation of the batteries may result in heat damage to the

batteries.

Re-insert the battery drawer into the monitor casing, and close.

OPERATIONS

1.3 INSTALLING THE OXYGEN SENSOR

The T-7 Oxygen Sensor must be installed before the instrument can be used.

Ensure that the monitor is switched off.

Remove the sensor from its protective bag. Inspect the sensor for damage or electrolyte

leakage. If the sensor is damaged obtain a replacement. Do not use the defective sensor as

it may be damaged.

Caution: the sensor electrolyte is caustic. Do not let it come into contact with skin. If it does,

immediately flush the affective area with water. Consult the Emergency First Aid procedures

as set out in the Material Safety Data Sheet for the sensor. Do not attempt to open or repair

the sensor. Leaking or exhausted sensors should be disposed of in accordance with local

regulations. Consult the Material safety Data Sheet supplied with the sensor.

Plug one end of the coiled cable into the telephone jack receptacle on the end of the

sensor. The jack will only fit one way, so if it does not fit, rotate it until it slides in easily.

Plug the other end of the coiled cable into the receptacle located on the right hand side of

the rear panel of the instrument. This jack will only fit one way, so do not force it.

Note : For sterilization procedures on the Oxygen Cell, see Section 3 on Page 15 below.

Caution : Do NOT autoclave the oxygen sensor
