    Area of Science:

    • Medical Devices
    • Respiratory Care
    • Intensive Care Medicine

    Background:

    • Manual resuscitators are critical for ventilation but can be used without supplemental oxygen.
    • Inconsistent oxygen delivery increases the risk of hypoxemia in patients requiring resuscitation.

    Purpose of the Study:

    • To develop and evaluate a device that automates supplemental oxygen delivery with manual resuscitators.
    • To ensure oxygen is supplied only when the resuscitator is in active use.

    Main Methods:

    • Development of an instant oxygen delivery valve for manual resuscitators.
    • Integration of the valve to automatically start/stop oxygen flow based on resuscitator use.
    • Testing the device's functionality and impact on oxygen flowrates.

    Main Results:

    • The developed device successfully automates supplemental oxygen delivery.
    • Oxygen flow is initiated upon resuscitator use and stopped when returned to its resting place.
    • The device does not compromise oxygen flowrates from the gas source.

    Conclusions:

    • This automated oxygen delivery system effectively prevents the use of manual resuscitators without supplemental oxygen.
    • The device offers a reliable solution for improving oxygenation during resuscitation in intensive care settings.
    • The system has been used successfully for several months in an intensive care unit.
