Based on Quality Detection Technology Standards of Ventilator presented by General Logistics Department, we tested parameters of ventilator using FLUKE VT-Plus-HF gas analyzer. By summarizing experience of quality test for many years, we found some indistinguishable problems and realized the necessity and importance of quality control test of ventilator. Based on current trial technical regulations, we scientifically establish the test procedures of ventilator, which could not only reduce defective percent, but also strengthen daily maintenance and management, so as to improve maintenance level and ensure medical safety.  www.jiuxin-med.com
