Note: At the end of this article, you can find a step-by-step video demonstrating how to remove and install the mouthpiece and turbine on the spirometer.

🛠️ Removing the Mouthpiece and Turbine

  1. Remove the Mouthpiece:

    • Grip the mouthpiece where it attaches to the turbine.

    • Simply pull it off the turbine, it should detach without twisting.

  2. Remove the Turbine:

    • Rotate the turbine counter-clockwise (anticlockwise) gently, this unscrews it from the device socket.

    • Once rotated, pull it straight out from the spirometer housing.

    If the turbine doesn’t turn easily, press lightly on its base while turning, and avoid using excessive force.

🔄 Installing a New/Replacement Turbine and Mouthpiece

  1. Insert the New Turbine:

    • Position it so the correct side faces outward (metal mesh toward the breathing path).

    • Push the turbine straight in to the housing.

    • Turn the turbine clockwise (right) until it stops and locks in place.

  2. Attach the Mouthpiece:

    • Align the mouthpiece with the turbine opening.

    • Press the mouthpiece into the turbine gently until seated securely.
