    An automated method accurately measures nitrous oxide levels in operating rooms, offering a cost-effective alternative for pollution control monitoring. This validated technique simplifies documentation and ensures environmental safety.

    Area of Science:

    • Environmental Science
    • Occupational Health
    • Analytical Chemistry

    Background:

    • Operating rooms can accumulate waste anesthetic gases, including nitrous oxide.
    • Effective monitoring of nitrous oxide levels is crucial for operating room safety and pollution control.

    Purpose of the Study:

    • To compare an automated method with a standard method for measuring time-weighted average nitrous oxide levels in operating rooms.
    • To evaluate the accuracy and cost-effectiveness of the automated method.

    Main Methods:

    • The automated method involved electronic integration of a nitrous oxide analyzer's voltage output using a multimeter-microprocessor.
    • The standard method used a bag and pump to collect room air samples for subsequent analysis.

    Main Results:

    • A high degree of correlation (r = 0.99) was observed between the automated and standard methods.
    • The automated method proved to be an accurate alternative for monitoring nitrous oxide.

    Conclusions:

    • The automated method provides a simple, cost-effective solution for monitoring and documenting nitrous oxide levels in anesthetizing locations.
    • This method supports institutions in managing pollution control programs effectively.
