QRS Orbit Spirometer Frequently Asked Questions:


  • Do I need to calibrate my spirometer? How often is calibration required?

    The QRS Orbit spirometer is pre-calibrated, as are the mouthpieces. QRS 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.
  • Can I connect via a USB port?

    Yes, the QRS Orbit directly connects to the PC via a USB cable.
  • How many times can I use the spirometer 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.
  • If I blow air down the pressure tube, how do I clean the spirometer?

    Air doesnêt 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 patientês 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?

    • FVC.
    • Pre/Post Testing.
    • Flow Volume Loop.
    • MVV.
    • SVC.
  • What predicted value studies are options in your spirometry testing software?

    FVC/SVC Predictors:

    • Adult: Crapo ê81, Cherniack ’72, Morris, Knudson ê83, Roberts ê91, NHANES III ê99, ECC/ERS/Quanjer â93.
    • Pediatric: Hsu ê79, Knudson ê83, Polgar ê71, Warwick ê77, NHANES III ê99, Zapletal ê87, Wang ê93, Quanjer â95.


    MVV Predictors:

    • Adult: Cherniack â72.
    • Pediatric: Polgar ê71, Zapletal â87.
  • How is the lung age calculated?

    Lung age is equal to the predicted FEV1 that matches the patientês 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 anyoneês 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.
