[title] Expiratory Flutter Valves
[* red] Expiratory flow is through one way flutter valves. These screw onto the loop and create an airtight, penetration through the bag.
[* black] Flutter valves are fashioned from a cut-off glove finger rubber banded onto Flutter Valve Penetrator. End of finger is cut to allow air exit, but stop reverse inflow.
[* icon_notegreen] Older, round flutter valve fittings also required addition of a valve deflector piece to pre-bend the glove finger.

[* icon_reminder] Bunny PAPR with correct inflow rate maintains continuous positive pressure. The flutter valves should rarely if ever need to close.
[* icon_caution] Test that your airflow and expiratory fittings configuration maintains bag inflated even during inspiration The bag should only collapse inward about 1 cm.
