[title] Expiratory Flutter Valves
[* red] Expiratory flow through the bag is through one way flutter valve. These screw onto the halo to form an airtight, penetration through the bag.
[* violet] 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 reverse flow is immediately stopped.
[* icon_note] Halo operates with continuous positive pressure, the flutter valves rarely if ever need to close. Even during inspiration, the bag remains slightly pressurized.
[* icon_caution] Never use flutter valve penetrators without glove tips acting as valves and reverse flow reserve volume.
