    Area of Science:

    • Medical Devices
    • Respiratory Care
    • Anesthesiology

    Background:

    • Effective suctioning is crucial in mechanical ventilation.
    • Existing methods for assessing suction flow can be complex or inaccurate.
    • A need exists for a versatile T-piece and a simple suction flow estimation technique.

    Purpose of the Study:

    • To describe a new T-piece adaptable to high- and low-pressure extraction systems.
    • To introduce a straightforward method for estimating suction flow.
    • To evaluate the suitability of the T-piece for use with automatic ventilators.

    Main Methods:

    • Design and description of a novel T-piece connector.
    • Development of a suction flow estimation technique based on timed water displacement.
    • Assessment of T-piece compatibility with standard automatic ventilators.

    Main Results:

    • The described T-piece functions effectively with both high- and low-pressure suction systems.
    • The water-emptying time method provides a simple estimation of suction flow.
    • The T-piece is suitable for integration with automatic ventilator circuits.

    Conclusions:

    • The presented T-piece offers a versatile solution for respiratory suction management.
    • The proposed method simplifies the assessment of suction flow rates.
    • This combination enhances the adaptability and usability of ventilation equipment.
