Introducing a significant advancement in Spirometry

Weighing only 10 oz., the IQmark Digital Spirometer is a great addition to Midmark's digital diagnostic family. The IQmark Digital Spirometer meets or exceeds the strict requirements of the American Thoracic Society and is easy to use. It supplies you with all the measurements you require from a diagnostic Spirometer. This includes FEV6 that is recommended by the NLHEP.

The IQmark Digital Spirometer enables you to perform FVC, VC and MVV tests as well as printing full-page reports on standard 8 1/2 x 11 paper. Performing Pre- and Post-Bronchodilator tests is straightforward for both you and your patients. The Spirometer utilizes a Disposable Pneumotach Mouthpiece that minimizes the chance of patient cross-contamination, ensuring safe and convenient testing. Using the Spirometer's data with smoking-cessation programs increases the success rate of the participants. By entering the patient's smoking history into the IQmark Digital Spirometer, it will automatically report the patient's Lung Age and COPD Risk. You can use this information to show your patients the current physical condition of their lungs.

Data-Management Philosophy

We know that many medical offices are either looking for Electronic Medical Records (EMR) software packages or have already incorporated an EMR into their practices. To address this, Midmark has created an integration software solution that enables EMRs to directly acquire diagnostic data into their database. Contact your Midmark representative to find out if your EMR is currently integrated or to discuss your future integration solutions.
