    A novel closed breathing circuit offers versatile functionality, operating without continuous gas flow by utilizing a demand valve. This adaptable system supports various anesthesia delivery methods and has proven effective in clinical settings.

    Area of Science:

    • Anesthesiology
    • Medical Device Engineering

    Background:

    • Traditional anesthesia circuits often require continuous gas flow, increasing costs and waste.
    • Existing closed circuits may lack flexibility for different clinical scenarios.

    Purpose of the Study:

    • To describe a new versatile closed breathing circuit with enhanced features.
    • To highlight the circuit's adaptability for various anesthetic techniques and patient needs.

    Main Methods:

    • The described circuit operates in a closed manner, replacing absorbed gas via a demand valve.
    • It incorporates features for continuous gas input and ventilator use.
    • A single control allows conversion to a non-rebreathing circuit.

    Main Results:
