| [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. |
