Frequently Asked Questions

  • How long does this test take?

    The test takes approximately 10 minutes.

  • Can the disposable hose be used more than once?

    The disposable hose (the METABREATHER™) is for single patient use only. It cannot be effectively cleaned between patients and the valves within the mouthpiece will not maintain accuracy through multiple tests.
