General Issues

How often should my Morgan system be serviced and have Preventive Maintenance?
All Morgan systems should be checked annually and have a PM service performed.This includes changing the Oxygen cell, evaluating the CO cell and installing a a comprehensive PM kit which replaces all items that can leak and cause potential problems. Included is a procedure where we set all system voltages and recalibrate all of your pneumotachs and analyzers. Included with a service agreeement is the certification of your calibration syringe. This is recommended by the ATS to be performed annually. Email us or call 800 399-0250 for a PM quote for your specific system and location.
How do I get replacement parts for my Morgan system?
Parts are listed on a document you can view as a download on our downloads page. Download or view the Morgan Accessory List under Morgan on our downloads page. Call 800-399-0250 and ask for customer service. If they cannot assist you please ask for the service department or email us your request. We will be sure you get the proper item and process your order the same day.

Calibration Issues

My Morgan pneumotach will not calibrate

Check that your gas pressures are on and set at 55 PSI +- 5 PSI.

Sometimes when doing the calibration check, the calibration will fall outside of the calibration ranges. This typically happens if the screen in the pneumotach is cleaned or changed. This can usually be remedied by "creating a new span factor" for the pneumotach. First, check that the connection to the patient valve has integrity. Be sure your calibration syringe and the connecting tube to the patient valve are firmly connected and the tube has no leaks in it. Check that the two small blue and red tubes are pushed firmly into the top of the pneumotach and that the tubes are in line next to each other and have no kinks. Check the certification date of your syringe. If it has not been certified within the last year it is out of American Thoractic Society's recommendations for syringe certification. Click here for syringe certification information.

To complete the span procedure for the pneumotach, open the ComPAS software. Click Tools - Diagnostics and a diagnostics screen will open. The "setup" tab along the right should be selected. Click on the "Create New Span Factor" button. Select the "Span F/V Pneumotach" button the bottom. Perform a calibration using at least two strokes in the low flow yellow areas and 1 in each of the two higher flow levels both expiratory and inspiratory. Repeat the same process using the "Span DLCO Pneumotach" button.

After completion, click the "Exit Service Mode" button to return to the regular calibration screen. Try calibrating again. If calibration still does not pass, repeat the above "span factor" procedure. If the problem persists call our serivce department at 800-399-0250. If your unit is not covered under a service agreement, there may be a fee for the call.

My Spiroair Spirometer will not calibrate or reports an error while centering

Check that your gas pressures are on and set at 55 PSI +- 5 PSI.

Sometimes when doing the calibration check, the spirometer calibration will fall outside of the calibration ranges. This typically happens if a calibration is interrupted or power is interrupted to the Spiroair. This can usually be remedied by recentering the spirometer and by "creating a new span factor" for the spirometer. First, check that the connection to the patient valve has integrity. Be sure your calibration syringe and the connecting tube to the patient valve are firmly connected and the tube has no leaks in it. Check the certification date of your syringe. If it has not been certified within the last year it is out of American Thoractic Society's recommendations for syringe certification. Click here for syringe certification information.

To complete the spirometer centering procedure, open the ComPAS software. Click on Tools - Diagnostics and a diagnostics screen will open. Select the "setup" tab on the right. Click on the "First Time Setup" button. The system will move the internal rolling seal spirometer back and forth and prepare it for calibration. After this first time setup procedure you must perform the span procedure detailed in the next paragraph.

To complete the span procedure for the spirometer, open the ComPAS software. Click Tools - Diagnostics and a diagnostics screen will open. The "setup" tab on the right should be selected. Click on the "Create New Span Factor" button. Select the "Span Spirometer" button at the bottom. Follow the syringe instructions until the "done" button appears.

After completion, click the "Exit Service Mode" button to return to the regular calibration screen. Try calibrating the spirometer again. If the spirometer still does not pass calibration, repeat the above "span factor" procedure. If the problem persists call our service department at 800-399-0250. If your unit is not covered under a service agreement, there may be a fee for the call.

My Gas Calibration will not pass or gives me an error

Check that your gas pressures are on and set at 55 PSI +- 5 PSI.

Several things can contribute to gas calibrations not passing. The most common problem is the small drierite/sodasorb canister (on the right side of the unit - Spiroair, left side - Bodybox, or front - Transair) or a leaking inspirate (large) bag on the patient valve. Try replacing the large bag and retry calibration. If this doesn't fix the issue, check the small canister on the right of the unit. Small crystals will sometimes get caught under the red rubber caps, and even more frequently the canister is not seated properly. Remove the canister and one end at a time, remove the red caps and clean any dust or crystals out of the grooves. Reseat the rubber caps and twist them slightly while pressing them down. Next reseat the canister making sure the red caps are seated properly on the black mount. Press the locking lever all the way down. Check that you are using the proper gas values (.3% CO, 10% He, 21% O2 with Balance N2) perform another gas calibration.

Sometimes an error will occur indicating that there has been a large change in the calibration of one of the gases in reference to the master record. This can be several things. Run a calibration and record the maximum voltages, during the time the lines are going up record the highest voltages of CO, He, and O2; at the time the three gas lines on the screen cross the 2nd vertical line. The voltages should be at or above the minimum acceptable values listed below. ***NOTE*** The CO voltage should plateau on intersection of the second vertical line. A CO voltage that does not plateau on intersection indicates a more serious problem requiring a service call.

NORMAL SPAN VOLTAGES = (From the Morgan troubleshooting document in downloads)

Helium: 4 - 8 volt range, typical voltages are 5.5 - 6.5. Below 4 volts the software will generate an
error message
Oxygen: 1 - 8 volt range, below 1 volt will flag the software and indicates that the cell should be
replaced
CO: 4 - 8.5 volt range, below 4 volts the software will generate an error message

 

IF THE VOLTAGES ARE NOT WITHIN THE ACCEPTABLE RANGES you need to call our service department at 800-399-0250, and schedule cell replacement and the equipment recalibration. If the system is not under warranty or a service agreement with Respitech Medical, there is a fee for this service. DO NOT RESET THE GAS MASTER RECORD or damage can occur.

ONLY IF THE VOLTAGES ARE NORMAL you can reset the gas master record. To accomplish this open the ComPAS software and click on Tools - Diagnostics and then click on the "Gas" tab along the right side. Click on the "Create Master Record" button. Exit the Screen and run another gas calibration. If this does not fix the problem, call our Service Department to schedule a service call. If the unit is not under warranty or under a service agreement with Respitech, there will be a fee for this service.

I need to have a change made on my PFT Report
If your unit is under warranty or under service agreement with us, changing reports to your desired design is performed at no charge. If not there may be a fee. It is desirable to have as many changes as you need made at one time to keep the cost of report designing down. Call our service department at 800-399-0250 to schedule a time to update your reports. We will request that you email our support department with the exact changes you desire. If your computer is online (has Internet) this cost is greatly reduced because we can update your report online vs having a technician come on-site.
How do I know my Values are correct?

The built in calibrations should ensure your system is calibrated and accurate. The best way to ensure your system is accurate is to have one or two "subjects" in the department who know their normal values. This can be determined by testing a few times to determine normal values. Using a clean filter, test your known subjects to see if their measured PFT values are reporting values as expected compared to their known values.

The Morgan uses "linear analyzers". This means the the analyzers do not need to be corrected for linear inaccuracies over the ranges they are used in. Because of this we recommend you test a known healthy subject to ensure the numbers are accurate. On our download page is an article from ATS which describes how to use a standard calibration syringe to check the low end (near zero) for a DLCO maneuver. View or download the article on our downloads page entitled "ATS DLCO QC Zero Procedure".
