QRS Orbit Spirometer - PC Based

The Orbit is a full-function portable spirometer that connects directly to your personal computer, laptop or tablet. This spirometer simplifies testing by eliminating calibration and sterilization with disposable nose-clips and pre-calibrated mouthpieces. The Orbit integrates with Office Medic and cooperates with your EMR system.

Now with Global Lung Initiative (GLI-2012) Equations

Measured Parameters – 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/FIVC, PIFR, FIF50%, FIF25-75%, FIF.2-1.2, FVC/FIVC, Extrapolated Volume, EOTV, FET, MVV, RR, MTV, SVC


Standards - The Orbit provides effective diagnostic tests and meets the following standards: 

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

Lung Age Calculation - Lung age is calculated for patients 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 Orbit spirometer system, everything the patient touches is thrown away. No sterilization or calibration is necessary, saving time for nurses, therapists and physicians.

No Batteries Required - The Orbit draws its power from the PC it is connected to by USB port.
