MetaBreather Valve and Tubing
The CardioCoach PRO MetaBreather valve is a two-way Non-Rebreathing
Valve (NRBV) designed to separate the patient's inspiratory and expiratory
flows at the low flow rates expected during a resting test. The valve is
single-use only and must be discarded after testing.
A disposable nose clip is included to ensure all exhaled air is analyzed
during a resting test.
