QRS SpiroCard™ PC-Card Spirometer
The SpiroCard turns an off-the-shelf computer into a full-function spirometer. It exceeds the ATS Standard and out-performs its competition. The SpiroCard is pressure-calibrated at the time of production so there is no need for routine calibration. The SpiroCard interfaces with Office Medic, bringing diagnostic testing right to the point-of-care.

Office Medic spirometry features included customizable reports, test overlays, 12+ predicted equations, lung age calculation and 25+ parameters. FVC, Pre/Post Testing, Flow Volume Loop, MVV and SVC tests can be performed with the SpiroCard and Office Medic. This software also has adult and pediatric incentives and Automatic Test/Session Quality Checks to encourage and ensure quality spirometry tests are performed. See Specifications for more detailed information.

The SpiroCard is pre-calibrated and uses disposable pre-calibrated mouthpieces, simplifying spirometry. No calibration or sterilization is required with this system. QRS has all consumables available necessary for performing the most accurate and reliable spirometry tests; pre-calibrated mouthpieces, nose-clips and a Volume Calibration Syringe. ATS Guidelines recommend the use of nose-clips and require a daily calibration check on devices.


The SpiroCard meets the following Standards:

  • ATS/ERS 2005 Standard
  • British Thoracic Society (BTS) Standard
  • NICE Guidelines

The SpiroCard was validated by the LDS Hospital’s Pulmonary Laboratory against 26 demanding waveforms and out-performed systems costing 10 times its price.¹ It was found to have unparalleled accuracy and exceeds the ATS Standard.
