Locking Ring| Male Plugs have Locking Rings and must be engaged when in use.
Oxygen Sensor| Galvanic Oxygen Sensor
Diverter Fitting| Fitting is used to connect to the Oxygen Source.

Tee Adapter

| The Tee Adapter is used to connect the Oxygen Sensor and Diverter Fitting to an oxygen pathway circuit.

Operating Instructions

Sensor Installation

CAUTION

• Inspect the Oxygen Analyzer, Sensor and Cable for visual damage before use, DO NOT USE if damaged.

• Inspect the Oxygen Sensor and Diverter Fitting for visual damage or electrolyte leakage before use. DO NOT USE if damaged.

• Use ONLY an Oxygen Sensor specified by Precision Medical, Inc.

• The Oxygen Sensor should not be used in the presence of flammable anesthetics such as Diethyl Ether or Cyclopropane.

• DO NOT attempt to open or repair the Oxygen Sensor.

• The Sensor electrolyte is corrosive and contains lead.

• DO NOT let Sensor electrolyte come in contact with the skin. If it does, flush the affected area with water.
  Check the Sensor regularly for leaks.

• If the Sensor is leaking, replace it with NEW Sensor. Leaking or used Sensors should be handled and disposed of in accordance with local regulations.

• An SDS is available from Precision Medical, Inc.

• If the Oxygen Sensor is used in breathing circuits, the Diverter must be attached to the Sensor and must be used with the Tee Adapter.

• The Oxygen Sensor must be installed before the Oxygen Analyzer can be operated.

1. Screw the Diverter to the bottom of the Oxygen Sensor, tighten until snug.
2. If using the Tee Adapter, attach to the Diverter.
3. Insert the one end of the Coiled Cable into the top of the Sensor, and secure by tightening the Locking Ring.
4. Insert the other end of the Coiled Cable into the Sensor Cable Connection located on the top of the Oxygen Analyzer. Secure it in place by tightening the Locking Ring.
5. Wait approximately 20 minutes for the NEW Sensor to stabilize to the environment.
6. Calibrate the Oxygen Analyzer with the NEW Sensor.

CAUTION

• Calibrate the Oxygen Analyzer before each use, and when replacing the Oxygen Sensor or the batteries.
• To ensure accuracy, the Precision Medical Oxygen Analyzer should only be calibrated using 100% Oxygen.
• Using any other concentration will result in possible inaccurate readings.
• Air calibration is not recommended unless the Sensor can be exposed to a known source of clean air. Hospital room air is often enriched with excess oxygen.
• Calibrate the Oxygen Analyzer at a pressure and flow similar to your application.
• Before calibrating the Oxygen Analyzer, the oxygen concentration readout should be stable and not drifting more than 0.2%.
• DO NOT calibrate the Oxygen Analyzer in humidified gas.

Calibration

The new calibration is required when:

• The measured O2 percentage in 100% O2 is below 97.0% O2. The measured O2 percentage in 100% O2 is above 100.0% O2.

• The CAL reminder Icon is activated on the LCD.
  If you are unsure about the displayed O2 percentage.

• A simple calibration may be made with the Sensor open to static ambient air. For optimum accuracy Precision Medical Inc. recommends that the Sensor be placed in a closed loop oxygen circuit where gas flow is moving across the sensor in a controlled manner. Calibrate with the same type of circuit and flow that you will use in taking your readings.

1. Follow Sensor Installation instructions above.
2. Attach an open-ended reservoir to the end of the Tee Adapter. Start flow of 100% oxygen at a pressure and flow similar to your application. Six to 10 inches of corrugated tubing works well as a reservoir.
   • A calibration gas flow to the Oxygen Analyzer of two liters per minute or more is recommended to minimize the possibility of obtaining a “false” calibration value.
3. Allow the oxygen to saturate the Sensor. Although a stable value is usually observed within 30 seconds, allow at least two minutes to ensure that the sensor is completely saturated with the calibration gas.
4. If the Oxygen Analyzer is not already turned on, do so now by pressing the Analyzer “ON” button.
5.  Press and hold the Cal button on the Oxygen Analyzer for at least 3 seconds to activate calibration. The Analyzer will detect a stable Sensor signal. When obtained, the Analyzer will display the assumed calibration gas on the LCD.

Effects of Elevation/Barometric Pressure Changes

• This device does not automatically compensate for changes in barometric pressure. Calibration of the Analyzer shall be performed when elevation at which the device is being used changes more than 500 feet.

Effects of Temperature

To minimize temperature effects:

1. In a breathing circuit, place the Oxygen Sensor upstream of the heater.
2. Allow time for the Oxygen Sensor to stabilize to its new room temperature.
3. Perform the calibration procedure at a temperature close to or similar to your clinical application

Effects of Humidity

• High Moisture levels will dilute the oxygen concentration, decreasing the concentration of oxygen being monitored by the Oxygen Sensor.
• High humidity can cause condensation to collect on the Oxygen Sensor, obstructing the passages and reducing the effectiveness of the Oxygen Sensor.

CAUTION

To reduce the effects of humidity on the Sensor:

• DO NOT USE the Oxygen Sensor in environments with greater than 95% humidity.
• Place the Oxygen Sensor upstream from the Humidifier in a breathing circuit.

Effects of Pressure

CAUTION

• The Oxygen Analyzer is not equipped with automatic barometric pressure compensation.
• The following recommendation is provided to reduce the chances of pressure causing false readings.
• Calibrate the Precision Medical Oxygen Analyzer using 100% oxygen or room air at the same pressure and flow as the gas to be analyzed.

Effects of Anesthetic Gases

Anesthetic Agent| Test Concentration| Oxygen Concentration Error
---|---|---
Helium| 50%, Balance Oxygen| 0%
Nitrous Oxide| 80%, Balance Oxygen| 0%
Carbon Dioxide| 10%, Balance Oxygen| 0%
Halothane| 4%| <1.5% Oxygen
Enflurane| 5%| <1.5% Oxygen
Isoflurane| 5%| <1.5% Oxygen
Sevoflurane| 5%| <1.5% Oxygen
Desflurane| 15%| <1.5% Oxygen*

• Test mixture = 30% O2, balance 70% N2O except where noted.
• Errors may vary based on concentrations and exposure times.

CAUTION

• The Oxygen Sensor should not be used in the presence of flammable anesthetics such as Diethyl Ether or Cyclopropane.

Cleaning

CAUTION

• DO NOT steam autoclave.
• DO NOT immerse the Oxygen Analyzer into any liquid.
• DO NOT use any strong solvent or abrasive cleaners.
• DO NOT allow any liquid to enter the Oxygen Analyzer or the Oxygen Sensor; this will damage the Oxygen Analyzer or Oxygen Sensor and will void the Warranty.

1. Disconnect all connections before cleaning.
2. Clean exterior surfaces of the Oxygen Analyzer, Tee Adapter and Coiled Cable with a cloth dampened with mild detergent and water.
3. Wipe dry with a clean cloth.
4. Wipe Oxygen Sensor and Diverter using a lint free dry clean cloth.

Maintenance

Sensor Replacement

• Reference “SENSOR INSTALLATION”

CAUTION

• Sensor Replacement must be performed by Qualified Personnel.

1. Replace batteries when “Low Battery” icon is displayed.
2. Remove 4 screws located on the back and remove cover.
3. Remove and replaced batteries with 2 new AA Alkaline batteries. Verify correct polarity.
4. Secure back cover onto the Oxygen Analyzer with the 4 screws.
