  • Measurement tutorial presentation system for increased patient compliance. The device plays a simplified video with human voice explanation on its own screen. The device explains to the patient its own usage with a tutorial comprising simplified video and audible text. In case of a poor manoeuver such as prematurely stopped FVC, coughing, slow starting, poor effort, short expiration, or failed reproduciblity, the device explains the reason of the poor manoeuver to the patient with human voice and also provides a direct tutorial which focuses on the reason of the poor manoeuver.
  • ATS/ERS and NLHEP interpretation systems for automated pulmonary diagnostics. The device automatically processes FVC trials and provides suggestions on how to improve manoeuver quality.
  • NHANES III, Knudson, Crapo and Hsu measurement prediction formulas included. Ethnic correction factor is directly supported.
  • Audible chirp during measurements to incite the patient to perform better manoeuvers.
