    Area of Science:

    • Respiratory Medicine
    • Pulmonary Diagnostics

    Background:

    • Sputum induction is crucial for diagnosing respiratory infections.
    • Existing methods can be complex or resource-intensive.

    Purpose of the Study:

    • To describe a simple, effective method for inducing sputum production.
    • To evaluate the efficacy and practicality of saline aerosol induction.

    Main Methods:

    • Utilized vaporized 15% aqueous sodium chloride (NaCl) solution.
    • Administered 15 inhalations of saline aerosol.
    • Included a 15-30 minute waiting period post-inhalation.

    Main Results:

    • Achieved a productive cough in 93% of participants tested.
    • The apparatus is portable, inexpensive, and easy to maintain.
    • Demonstrated suitability for both field and hospital environments.

    Conclusions:

    • Vaporized 15% NaCl aerosol is a highly effective sputum induction technique.
    • The method offers a practical, low-cost solution for respiratory sample collection.
    • This approach enhances diagnostic capabilities in diverse clinical settings.
