Abstract：Objective The quality of ventilators in hospital is checked regularly, in order to guarantee
the safety of clinical. Methods According to the test items and methods for ventilators from
“Standard for Quality Control of Medical Equipment (Trail)” and applying the American FLUKE
ventilators gas flow detector (VT-PLUS), the data of ventilators, including the tidal volume of
ventilators, the ratio of forced ventilation frequency and respiration, the concentration of inspired
oxygen, the suction pressure, the PEEP levels, and other parameters, were measured. Results
According to test and maintain all ventilators of our hospital from 2010 to 2014, it is clear to understand
the working status of ventilators and maintain the quality problems of ventilators, as well as
improving safety in use of ventilators and guaranteeing the requirement of clinical departments.
Conclusion Detecting parameter values of ventilators have important clinical reference values to
evaluate operating status of ventilators.
