| [title] Expiratory Flutter Valves |
| [* red] Expiratory flow is through one way flutter valves. These screw onto the halo 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 negative pressure inflow. |
| [* green] A clip-on deflector bends glove finger at base to improve valve performance |
| [* icon_note] Halo 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 positive pressure even during inspiration The bag should remain pressurized during inspiration.
