Pony FX

Advanced Desktop Spirometer with spirometry, airway resistance and respiratory mechanics

  • Pony FX is the new generation of desktop spirometers developed by COSMED for complete spirometry (FVC/SVC, MVV, bronchial provocation) and respiratory mechanics (MIP/MEP, Rocc) testing. With a large colour LCD screen and inbuilt thermal printer, it is possible to perform tests without the need of a computer.

    The Pony FX has internal memory, which can store many patients/tests, and comes with a powerful and user-friendly PC software (OMNIA) for data management and real-time PC testing.

    Pony FX is configured with an accurate and reliable bidirectional digital turbine flowmeter.
    Additional optional tests include: Airway Resistance (Rocc/Rint) and Pulseoximetry (SpO2).

    Two different Pony FX models are currently available:
    • Pony FX: desktop spirometer with COSMED validated digital bidirectional turbine flowmeter.
    • Pony FX MIP/MEP: desktop spirometer for basic spirometry tests and respiratory mechanics measurements (MIP/MEP).

  • Key Features
    Desktop spirometry family. The 4th generation of the most sold desktop spirometer is available with two models Pony FX and Pony FX MIP/MEP.

    Standalone use. Compact desktop device with internal rechargeable battery, a large LCD screen and in-built thermal printer that allow testing without a computer or mains power lead.

    Powered by OMNIA. OMNIA allows intuitive, immediate spirometry testing with advanced text interpretation and graphical tools for quick assessment. Includes new standards and predicteds according to latest ATS/ERS guidelines (2005 Consensus, GLI, etc).

    Pediatric Incentivation. Possibility to perform spirometry test with a selection of innovative pediatric incentivation graphics with user defined effort grade on both volume and flow (both PEF and FVC predicteds).

    Additional PFT test features. Spirometry tests with Pony FX can be complemented with additional tests like respiratory mechanics (MIP/MEP), respiratory resistance (Rocc), integrated pulseoximeter (SpO2).

    Validated Digital Turbine Flowmeter. Independently validated turbine flowmeter by LDS Hospital using the ATS 24 standard volume-time waveforms (Crapo R. O. 2004 “Validation of COSMED turbine vs ATS 24 standard volume-time waveforms“).
