[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 reversenegative pressure flow is immediately stopped.
[* icon_note] Halo operates with correct inflow rate maintains continuous positive pressure, thepressure. The flutter valves should rarely if ever need to close. Even
[* icon_caution] Test that your airflow and expiratory fittings configuration maintains positive pressure even
during inspiration, theinspiration The bag remains slightly pressurizedshould remain pressurized during inspiration.
[* icon_caution] Never use flutter valve penetrators without glove tips acting as valvesDO NOT modify design to stent bag open. We want the bag to readily collapse. Bag collapse prevents negative pressure so you avoid reverse flow should inflow become marginal.
