It is highly recommended to calibrate a spirometer with Bionet 3L calibration syringe periodically, in order to ensure accurate calibration of your spirometer.

Our calibration recommendations are based upon guidelines from the American Thoracic Society (ATS) and the European Respiratory Society (ERS)

• The volume accuracy of the spirometer must be checked at least daily with a single discharge of a 3-L calibrated syringe.
• At least quarterly, volume spirometers must have their calibration checked over their entire volume range using a calibrated syringe or an equivalent volume standard. The measured volume should be within 3.5% of the reading or 65 mL, whichever is greater. This limit includes the 0.5% accuracy limit for a 3-L syringe.

SPM-300 is a spirometer sensor which works with the Cardio7-S and SpiroCare. SPM-300 uses a disposable sensor, so it is very easy to maintain because the sensor does not require disinfecting between uses. These disposable sensors make an accurate measurement possible every time.

By adding the SPM-300 to the Cardio7, you can test FVC, SVC, MVV and perform a pre-post bronchodilator comparison. Real-time volume-flow and time-flow monitoring is provided on the color LCD display. 120 tests are stored and a full size printout is provided for easy charting.

The disposable mouthpiece, SmarTube, is used. This makes it very easy to maintain the system because the sensor does not require disinfecting between uses. These disposable sensors make an accurate measurement possible every time.
