Standards – The SpiroCard provides effective diagnostic tests and meets the following Standards:

  • American Thoracic Society (ATS/ERS) 2005 Standard
  • British Thoracic Society (BTS) Standard
  • National Institute for Health & Clinical Excellence (NICE) Guidelines


Lung Age Calculation – Lung age is calculated for patients ages 20-84. It is equal to the predicted FEV1 that matches the patient’s actual FEV1. Lung age may differ based on the predicted equation chosen.

Patented, Pre-Calibrated Mouthpiece – With the SpiroCard spirometry system, everything the patient touches is thrown away. No sterilization or calibration is necessary, saving time for nurses, therapist and physicians.

No Batteries Required – The SpiroCard draws its power from the PC it is connected to via USB port.



The SpiroCard comes equipped with everything you need to begin testing.

  •  SpiroCard
  •  QRS Pre-Calibrated Mouthpieces, 2
  •  Pressure Tubes, 2
  •  USB Adapter
  •  Office Medic Software


Also included with the SpiroCard is a three-year warranty.
