Invacare Check O2 Plus Oxygen Analyzer (Invacare IRC450 replaces IRC400) is an efficient and cost-effective tester designed with technicians in mind. It includes the connection to make three separate checks: 1) oxygen purity concentration percentage, 2) flow rate in liters per minute, and 3) oxygen outlet pressure (psi/kPa) on any home or portable Oxygen Concentrator. This Oxygen Analyzer is very low maintenance and never needs to be calibrated. This tester features simple, two button operation. The device is powered by two AA batteries that provide over 16,000 readings before they need replacing or recharging. the Invacare oxygen analyzer is very efficient and will even shut off automatically after four minutes to extend battery life.

Low Oxygen Levels
Periodically checking the oxygen output levels of your oxygen concentrator is important. Settings can change. The altitude the concentrator is operating at can degrade the performance of the concentrator. Checking the actual output and adjusting the controls accordingly can help ensure you always get the amount of oxygen your need. Below are some symptoms experienced by oxygen patients when their oxygen level is too low.
- Shortness of Breath
- Chest Pain
- Rapid Breathing
- High Blood Pressure

Does the device need to be calibrated?
This device provides self-diagnostics and does not require any in-field calibration.
To check oxygen concentration, flow and pressure of the gas sample from a concentrator:
- Connect the gas sample tubing to the gas inlet port of the device.
- Attach the other end of the gas sample tubing to the oxygen concentrator.
- Initiate the flow of gas to the device at a rate of 1-10 liters per minute (2 liters per minute recommended). Ensure the concentrator’s output is stable per the concentrator manufacturer’s recommendations.
- Turn on the device.
- Allow the oxygen reading to stabilize for approximately 10 seconds before reading the oxygen concentration and flow.
- To check pressure, cover the gas sample outlet with thumb or finger while gas is flowing.
- Wait 5 seconds for the display to read pressure.
Self Diagnostic Features
The device has self diagnostic features built into the software to detect faulty readings outside of normal operating ranges. The codes, descriptions and recommended actions are as follows:
- E01: Oxygen measurement out of range Hi ( ³ 102.0% calculated by algorithm). Recommended Action: Verify that the device Plus is being used in the correct mode (Concentrator or Calibration Verification mode). If error code repeats; perform a calibration verification. If error code repeats again; Call Service Provider.
- E02: Oxygen measurement out of range Low ( £ -2.0% calculated by algorithm). Recommended Action: Verify that the device is being used in the correct mode (Concentrator or Calibration Verification mode). If error code repeats; perform a calibration verification. If error code repeats again; Call Service Provider
- E03: Device memory corrupt or missing. Recommended Action: Call Service Provider.
- E04: Signal reading not stable. Recommended Action: Call Service Provider.
- E05: Pressure measurement out of Range Hi ( ³ 50 PSI). Recommended Action: Check the pressure on a known gas source pressure. If error code repeats; Call Service Provider. • E06: Outside of operating temperature Hi ( ³ 40° C). Recommended action: The device is too hot, cool the device closer to room temperature before use.
- E07: Outside of operating temperature Low ( £ 15° C). Recommended action: The device is too cold, warm the device closer to room temperature before use.
- E08: Device self check found error. Recommended Action: Remove and replace the batteries. If error code repeats; Call Service Provider.
Improper use of the device can cause inaccurate oxygen readings leading to improper treatment or patient harm. Follow the procedures outlined in the user manual.
- Users must become thoroughly familiar with the information contained in this User Manual before use. Strict adherence to the operating instructions is necessary for safe, effective product performance. This product will perform only as designed if operated according to the manufacturer’s operating instructions.
- DO NOT use the device to measure the oxygen concentration of a concentrator when flowing at rates lower than its optimal performance as specified by the concentrator manufacturer; generally 4 LPM or less on concentrators that have a maximum flow of 10 LPM, and 1 LPM or less on concentrators that have a maximum flow of 5 LPM.
- Use of the device near devices that generate electrical fields may cause erratic readings.
- Exposure of the device to liquids from a spill or immersion requires immediate removal of the batteries. Let the device dry completely. When dry, replace the batteries and check for proper operation.
- DO NOT autoclave or expose the device to high temperatures (>60° C [140° F]).
- DO NOT use ethylene oxide sterilization.
- DO NOT expose the device to irradiation, vacuum, steam, or harsh chemicals. DO NOT expose the device to pressure greater than 50 psi. Exposure to pressure above 50 psi could cause leaks in the device which may adversely affect flow and pressure readings.
- Repair or alteration of the device by anyone other than a qualified technician could cause the product to fail to perform as designed.
- Not for use in anesthesia applications or for measuring oxygen concentration from any sources other than conventional oxygen concentrators.
- Not for use with inhalation agents. Operating the device in flammable or explosive environments may result in fire or explosion.
- Not suitable for use in the presence of flammable anesthetic mixtures.
- Oxygen rapidly accelerates combustion. Do not smoke while using the device for checking oxygen concentrators.
- NOT for use in an MRI environment.
- Replace the batteries with high-quality AA Alkaline or Lithium batteries. DO NOT use rechargeable batteries.
- When not in use for periods greater than 30 days remove the batteries to protect the device from potential battery leakage.
- Avoid dropping the device to prevent damage which may adversely affect its performance. If damage to the device is suspected, perform 4.3 Calibration Verification Procedure, page 10 of the User Manual.
- Avoid foreign matter entry into the unit.
- DO NOT use the device to check a concentrator with a humidifier in place. Humidity could damage the device.
- DO NOT check a concentrator while holding the mode button or the reading will be inaccurate.
- Following storage in extremely hot or cold conditions, allow the gas to flow through the unit long enough for the internal sensors to reach the gas stream temperature, or wait for the machine to equilibrate to room temperature before use.
