    Area of Science:

    • Anesthesiology
    • Respiratory Medicine
    • Medical Device Engineering

    Background:

    • Double-lumen endotracheal tubes (DLTs) are crucial for lung isolation during thoracic surgery.
    • Accurate inflation of the bronchial cuff is essential for effective lung separation and to prevent airway injury.
    • Inadequate cuff inflation or accidental deflation can lead to complications such as hypoxemia or endobronchial intubation.

    Purpose of the Study:

    • To describe a simple apparatus for precise bronchial cuff inflation of DLTs.
    • To present a method for detecting accidental bronchial cuff collapse.
    • To enhance the safety and efficacy of DLT use in clinical practice.

    Main Methods:

    • Development of a straightforward apparatus for monitoring DLT bronchial cuff pressure.
    • Implementation of a method to ascertain the exact end-point during cuff inflation.
    • Integration of a detection mechanism for spontaneous cuff deflation.

    Main Results:

    • The described method allows for the attainment of an exact end-point during bronchial cuff inflation.
    • The apparatus successfully detects accidental collapse of the bronchial cuff.
    • This provides a reliable means to ensure proper DLT function.

    Conclusions:

    • The developed apparatus and method offer a simple yet effective solution for managing DLT bronchial cuffs.
    • This innovation can improve the reliability of lung isolation and reduce the risk of associated complications.
    • It represents a practical advancement in airway management technology.
