What is the CEB®
Simply, it is a color coded index number that measures the degree of di-polarity of the cardiac electrical field. The cardiac electrical field of a healthy patient is primarily di-polar1, while occurrence of myocardial injury leads to the appearance of a multi polar cardiac electrical field2. A CEB® greater than 94 indicates an abnormal condition and further clinical assessment is necessary.

How do you use the CEB in a clinical setting?
It is used as an additional tool to alert clinicians that a patient may have an abnormal condition that requires additional assessment.

Warranty & Misc.

What is the warranty for the Universal ECG?
3-year hardware warranty on device – 1 year warranty on lead wires and PC connection cable.  For additional details, visit the hardware warranty page within Customer Care.

What if I break a lead wire?
Send the broken cable(s) to a certified VectraCor service center to repair the broken lead wire(s).  Request an RMA Number here.

Can I clean the device with alcohol?
No, you should only clean the cable with a clean cloth moistened with water. Alcohol will damage the plastic over time and may cause the case to crack.


Do I need to calibrate my spirometer? How often is calibration required?
The VectraCor spirometers are pre-calibrated, as are the mouthpieces. VectraCor spirometers do not require calibration, however, the software does allow for calibration checks in the field with a 3-liter calibration syringe. If you believe your device is out of calibration after testing several mouthpieces, please contact QRS Customer Care.
How much does the Orbit Portable Spirometer weigh?
0.5 lb.
Can I connect via a USB port?
Yes.  The Orbit directly connects to the PC via a USB cable.



How many times can I use the mouthpiece?
Mouthpieces are single patient use only but can be used up to 20 times over a 10 day period for that patient, if fabric does not become contaminated. The patient should open, handle and dispose of his/her own mouthpiece and should return it to its plastic bag to avoid contamination if future use is anticipated. Never use the same mouthpiece on different patients.
How does the mouthpiece handle cross-contamination?
Mouthpieces are single patient use only. The patient should open, handle and dispose of his/her own mouthpiece and should return it to its plastic bag to avoid contamination if future use is anticipated. Never use the same mouthpiece on different patients.  See the next question for additional details.
If I blow air down the pressure tube, how do I clean the spirometer?
Air doesn’t go down the tube; only pressure travels through the tube. There is a static pressure column created between the end of the mouthpiece and the pressure transducer inside the spirometer. The patient’s exhalation follows the path of least resistance, the vents on the side of the mouthpiece, thereby preventing moisture from entering the pressure tube.
To illustrate take a pressure tube that can be discarded. Attach the pressure tube to the mouthpiece and cover the opposite end of the pressure tube with your finger. Breathe through the mouthpiece. Notice the lack of moisture in the pressure tube and repeat. Moisture will never be present. This demonstrates that if used properly the pressure tube will not become contaminated. If a patient covers the vents on the mouthpiece or uses the pressure tube when it is not properly connected to the spirometer, the pressure tube must be replaced.

When do I need to replace the pressure tube?
The pressure tube can be reused on multiple patients (no quantity limit). QRS suggests replacing the pressure tube if condensation forms in the tube or if the tube is kinked or becomes occluded. If a patient covers the vents on the mouthpiece or uses the pressure tube when it is not properly connected to thespirometer, then the pressure tube must be replaced.  Store the pressure tube in a cool dry place to avoid condensation forming in the tube.
Why do I need to use a nose-clip when performing a spirometry test?
Nose clips are not required for spirometry tests, however the ATS Guidelines recommend using a nose clip to prevent air leaking out of the nose during the test. To get the most accurate results, no leaking can occur.



What parameters do QRS Spirometers measure?
FVC, FEV0.5, FEV1, FEV6, FEV3, FEV1/FEV6, FEV1/FVC, FEV3/FVC, PEFR, PEFT, FEF25%, FEF50%, FEF75%, FEF25-75%, FIVC, FIV0.5, FIV1, FIV3, FIV1/FIVC, FIV3/FVC, PIFR, FIF50%, FIF25-75%, FIF .2-1.2%, FVC/FIVC, Extrapolated Volume, EOTV, FET, MVV, RR, MTV, SVC
What tests can I perform with my spirometer?
• Pre/Post Testing
• Flow Volume Loop
What predicted value studies are options in your spirometry testing software?
FVC/SVC Predictors:

  • Adult: Crapo ’81, Cherniack ’72, Morris, Knudson ’83, Roberts ’91, NHANES III ’99, ECC/ERS/Quanjer ‘93
  • Pediatric: Hsu ’79, Knudson ’83, Polgar ’71, Warwick ’77, NHANES III ’99, Zapletal ’87, Wang ’93, Quanjer ‘95

MVV Predictors:

  • Adult: Cherniack ‘72
  • Pediatric: Polgar ’71, Zapletal ‘87

How is the lung age calculated?
Lung age is equal to the predicted FEV1 that matches the patient’s actual FEV1. Lung age is calculated for patients between 20-84 years old. If anyone falls outside this age range then the Lung Age will not be calculated. Also if anyone’s calculated Lung Age falls outside of 20-84 years old then a Lung Age will not be displayed by the software.  Note – lung age may differ based on the predicted equation chosen. Reference: Morris JP, Temple W.; Spirometric “lung age” estimation for motivating smoking cessation. Prev Med. 1985 Sep: 14)5):655-62. Age Range: 20-84.

What Operating System does my hardware run on?
Your hardware relies on drivers that ship with the Office Medic software. Refer to the System Requirements in Customer Care and choose your spirometer or the document that shipped with your product.


How do I turn on/off my Opti monitor?

To turn ON, press and hold the start/stop button until you hear a series of 3 quick beeps. To turn OFF, press and hold the start/stop button until you hear a series of five beeps.

Does the Opti or its cables contain Latex?

OptiFit Cuffs

Why is it important to use the correct size cuff on my patients?

The OptiFit cuffs are designed to meet the AAMI (Associate for the Advancement of Medical Instrumentation) clinical standards for blood pressure cuffs. These standards were devices in order to ensure adequate pressure on the artery of the upper arm, which is necessary to produce an accurate blood pressure measurement. If a cuff is used on an arm larger that the specified range, the resulting reading will be falsely high. If a cuff is used on an arm that is smaller than the specified range, the resulting reading will be falsely low.

How do I clean the OptiFit cuff?

The following cleaning methods have been applied 20 times to the cuff without any apparent negative effects:

  • Medical Disinfectant Spray – The cuff may be sprayed with a mild disinfectant solution, rinsed with distilled water, and line dried. Ensure that no liquid enters the bladder tubing.
  • Medical Disinfectant Wipe – Use a mild disinfectant wipe and thoroughly wet cuff surface and line dry.
  • Machine Wash – Remove bladder to machine wash the cuff shell. Machine wash warm (50-130° F, 10-54°C) with a mild detergent and line dry.


What Operating System can Opti-Insight run on?
The Opti-Insight software will run on the latest Operating Systems. Version 3 – Supported on Microsoft Windows 98, 2000, ME, XP. Version 2.x – Supported on all Microsoft Windows Operating Systems 95 and above.

Can Opti-Insight export data to be used in a spreadsheet or database?
The Opti-Insight software can export data to be used in a spreadsheet or database. Use the File >> Export function, Opti-Insight can be exported into an ASCII text file for use by most spreadsheet and database programs. The export function is flexible enough to allow for only data of interest and be exported and various of delimiters can be chosen

Does Opti-Insight allow for sending reports by e-mail or modem?
All files from the Opti-Insight software products can be sent via email and be opened with the corresponding Opti-Insight program that originally downloaded them. Also, all Opti-Insight software products can send reports over a modem to a fax machine when used with a PC with a fax-printer driver installed.

How do I get my Opti-Insight software to work with my EMR?
Opti-Insight has a one button operation to create patient reports in PDF format. PDF files of paitent reports can then be placed into the paitent’s folder for most EMR systems. This allows viewing of a patient’s report without the need for Opti-Insight.

I can’t get my computer to communicate with my monitor. Or, when trying to program or retrieve data, I receive the error, “Cannot communicate with ABP device.” How do I fix this?
Check the hardware settings under CONFIGURE, then PREFERENCES. Select a configuration to EDIT. Serial Port will show all ports available on the computer.

Why is the LCD showing E and a number?

This is an error code which can indicate three possibilities:

  1. Unsuccessful measurements
  • E-1 – too much movement by the patient: instruct patient to move less
  • E-2 – manually aborted measurement: ask patient about the cause of abort
  • E-3 – batteries run down during measurement: replace batteries
  • E-4 – batteries were replaced during measurement: no action necessary
  • E-8 – preset pressure limit exceeded: use higher preset limits
  • E-9 – static discharge, temporary disturbance: no action needed if it is not frequent. If this error happens frequently then please contact your local distributor’s support team.
  1. Cuff related errors (31-34)
  • Check if the cuff is properly connected to the device and properly put on the patient’s arm.
  • If you have a spare cuff then connect it to the device and test it.Contact your local distributor’s support team if the error is still present.
  1. Device errors
  • E-90 – if this is a constant error, then please return the device to your local distributor’s support team
  • E-99 - check if the cuff size is properly selected in the software. Contact your local distributor’s support team if the error is still present.

The LCD does not show the correct time, how can I set it?

  • Please connect the device to the PC and program it. The clock should selfadjust
    to the correct time.

Do I have to use Vectracor flash/memory cards in the Q200/HE recorder?
Flashcards from other vendors may be used in the recorders, however, because some card manufacturers provide memory cards which draw too much battery current, some cards may cause the batteries to be depleted prematurely resulting in the Holter stopping early. Because of this, we recommend that you first test cards purchased from another vendor for a greater amount of time than the expected use. Also, before using a new flashcard, you will need to format the card using the INITIALIZE function in the Holter program.

Can I use SDHC flashcards instead of SD cards in my Q200/HE recorder?
No. These are not supported in the Q200/HE recorder.

When should I replace a cable?
A problem with your recordings may be the result of a cable that is not functioning properly because it is damaged or old. First check to see if your cable is damaged or badly worn, if so, it should be replaced. Even if the cable appears to be fine, a cable that needs replacing may result in one or more of the following issues:

  • Poor quality hook-ups – any or all channels are artifact
  • Low voltage QRS
  • Lead quality test always below 3

How do I care for the cable?
By properly caring for your cables you can keep them in a good working condition for an extended period of time.

  • Don’t bend or wrap wires around recorder
  • Clean leads between uses with metricide or bleach
  • Keep electrodes at the right temperature.
  • Ensure electrodes are new – not dried out or rusted.
  • Check cable for breakage between uses.

Function Issues

Why is my recorder continually counting and won’t begin recording?
Remove and erase the card using the Holter program and reinsert. If this does not solve the problem, please call your distributor or VectraCor Customer Care for further troubleshooting or an RMA#.

Why is my recorder stopping before it should?
The shortened recording times may occur because the Holter is shutting down due to a depleted battery.  One cause of premature battery depletion is flash/memory cards that draw too much current. The memory card provided by VectraCor has been tested to meet the specification of the Holter unit, drawing a low current to maximize battery life. There are a number of memory card manufacturers and vendors who provide memory cards with much greater current draw. Flash/memory cards vary greatly with respect to the current that they use, even when purchased from the same manufacturer. They still meet the specification for the card, but achieve it at the expense of very high current. This high current will deplete the battery in less than the desired recording time.  Lexxar and SanDisk are two manufacturers that have been tested and are recommended for use with the Q200/HE. If you choose to purchase cards from other manufacturers, test the card for a greater amount of time in the Q200/HE recorder than the expected use to determine its effect on battery life.

Why am I getting a “Memory Full” error message and a short recording?
The patient’s Holter data is stored in the recorder on a removable SD card. To store 24 hours in normal mode, 28 megabytes (MB) is required. To store 24 hours in high mode, 56 MB are required, and a 14-day recording in high resolution mode would require about 760 MB. To view the actual size of the flash.dat file on your card, put the card in the reader and view the file when you are prompted to do so. If you have enough capacity on your SD card, but are getting short recordings, the flash.dat file on your SD card may have been corrupted. You can fix this problem by reformatting and re-initializing your card. The instructions for doing this can be found in the Holter LX Analysis International User Guide starting on page 4. If you sometimes do recordings that are more than 48 hours, be sure to choose the option that does not specify "less than 48 hour recording." Also, be sure to allow the process to complete before removing the SD Card from the reader.

How do I remove the flash/memory card from the Q200/HE recorder?
Gently press inward on the SD card to release. The card will pop-out. Never pull the card out – it may damage the recorder.

Which software should I use with my Q200/HE?
To use the Q200/HE in Holter mode, you must have some level of Holter LX Analysis software. The levels are Enhanced, Enhanced Plus and Pro. Each level offers different capabilities; download the Holter LX Analysis Features Matrix learn more about each level of software. To use the Q200/HE in telephonic Event mode (this is the most common method of transmitting event recordings), you can use ANY event software. However, using our LX Event software makes life a bit easier and guarantees that the telephonically transmitted data with patient header information will be correctly/automatically received by the receiver. To use the Q200/HE in data card Event mode (this special mode is available only to users of our hardware and software), you must use our LX Event software.

How do I edit the Patient ID if I make a mistake while entering it into the Q200/HE recorder?
When entering the characters for the Patient ID, press the ENTER button to advance from one character to the next. If you need to backspace, hold down the ENTER key for a bit longer than normal. When you have entered the complete Patient ID, finish by pressing the EVENT button. Once you have entered the Patient ID and completed the process by pressing and holding the EVENT button, the only way to change the Patient ID is to remove the battery and start over again. See, "To Start the Recorder for Holter", on the Q200/HE Hook-Up Guides.

My Q200/HE recorder is displaying a “Lead Loose” message – what does this mean?
Electrodes that are dried out will cause this message to appear and should be replaced. However, some types of electrodes, including the new, high-impedance gel formulations, cause the “Lead Loose” message to be displayed even though there is not an issue with the signal quality. If you are receiving an adequate signal, you can turn the “Lead Loose” message off under “Settings.”

How do I switch the Q200/HE recorder from Event monitoring to Holter recording?
After deleting the events by pressing either arrow for 3 seconds, reboot the recorder by removing and reinserting the battery. Then, interrupt the 15-second countdown by pressing ENTER, down arrow, up arrow and the EVENT button. Now press ENTER and go to the General Settings menu where you can change the recording type from Event to Holter. The Q200/HE Hook-Up Guides in your hardware kits also tell you how to start your recorder for Holter or Event.


What should I do when I get the message, “Flash file not found” on my computer?
First, make sure that the card reader is plugged in and that a card is inserted correctly into the reader. Second, it may be that your computer can no longer see your Card Reader. To fix this, remove card reader plug from the computer and plug into a different USB port on the computer. Third, try turning off and restarting your computer. If you still cannot see the Flash file, your reader may need repair. Try using another reader if available, or call your distributor or VectraCor Customer Care for further assistance.

What do I do when I see the message, “Card has files other than flash.dat, use Explorer to erase?”
This means that there are files on the card other than flash.dat. You must remove these files using Windows by clicking on “Start” and then “My Computer”. Double-click on the appropriate Removable Disk to see all of the files on the card. Delete all files except for flash.dat.

How do I install the Holter LX Analysis software?
Installation instructions were included in your software kit and also can be found in the Holter LX Analysis Software Manuals. If you encounter problems in the Installation process, contact your distributor or VectraCor Customer Care.

How can I customize the Holter LX Analysis software?
Refer to the Holter LX Analysis manuals for instructions on how to customize the software using the CONFIGURATIONS feature.

How often should I back up my Holter data?
Back-ups should be done on a regular basis as determined by your organization. In order to do backups, your computer must have a CD drive. Instructions on how to back up your software is included in the manual.

What should I do when the software identifies pauses that are not real?
If the QRS complexes are very small, some of them can be missed so that the software identifies false positive pauses. If that happens, go to REVIEW > CALIBRATION, move the calibration lines as close to the baseline as possible, and press DONE. The software will reanalyze the signal using a higher gain and find the small QRS complexes.

How do I change Holter LX Analysis to an alternate language?
In order to set up an alternate language in Holter LX Analysis, you will need to do the following:

  • Install software on your desktop
  • Open the Utilities screen and change the language to what you desire.
  • Open Holter LX Analysis and go to File > Preferences > Configurations.
  • Save one more new configuration by copying the "Standard" and saving the new configuration with a name of your choice.

Why won't my Office Medic install on my Windows 10 PC?
You may have an older version of Office Medic that is not validated to work with Windows 10. See how to upgrade to the latest version (see page).
