True modularity
The Quark PFT’s modular, expandable architecture supports both lung function and metabolic testing in a single platform, helping reduce operational costs while simplifying service and maintenance.
Intuitive workflow
OMNIA’s streamlined workflow guides users from data entry through test interpretation, reducing training time and simplifying daily operation.
Automatic interpretation
A built-in interpretation algorithm processes results according to the latest scientific guidelines and generates interpretive reports with numerical values and graphical data.
Compliant
The Quark PFT and OMNIA comply with the latest international guidelines, including ATS/ERS standards for spirometry, DLCO, Lung Volumes and Airway Resistance.
Network ready
The Quark PFT can be installed as a standalone workstation or integrated into small or large network environments, with the ability to share data directly with electronic medical record (EMR).
OMNIA Software
The Quark PFT includes OMNIA, COSMED’s modular software suite, featuring an intuitive interface and guided workflows that reduce training time and simplify daily operation.
