The detection of ductwork ventilation efficiency is a basic technical method and method for the effectiveness evaluation of occupational health protection engineering, and it is also a necessary process for the diagnosis of existing problems in the ventilation system. According to the occupational health evaluation of the parameters, such as ventilation efficiency assessment requirements, this paper introduces the ventilation pipe of the measurement of wind speed and wind pressure and illustrates the concept and method of the new air volume and air changes; the use of the commonly used measuring instrument was introduced in detail; the field measurement method and the calculation process are presented to avoid to produce error methods, requirements, and matters needing attention;   That how to select measuring method, measuring instrument and its suitability according to work condition are expounded, which has guiding reference for pipe ventilation efficiecy testing and evaluation.
