上海市公共卫生应急人员口罩适合性情况调查
|
摘要
目的建立应急人员口罩适合性数据库,指导疾病预防控制机构合理配置各型口罩。方法采用仪器法,对登记在册的上海市公共卫生应急处置人员进行3种口罩的适合性测试。结果共测试1 133名人员,Real-time测试通过率为93. 91%; 69名未通过,310名人员未通过任何口罩的Fit test,测试通过率为72. 64%,所测试的口罩中仅有66. 55%可以满足公共卫生应急人员的需要。公共卫生应急人员配备的3种进口品牌口罩适合性测试通过率范围在21. 45%、38. 75%和9. 4%。结论上海市公共卫生应急医用防护口罩种类稍显不足,使用中漏气的风险最大,应进一步验证应急防护口罩的有效性。
Objective To establish a database of mask fitness for emergency personnel,and to instruct the institutions for disease control and prevention to properly allocate various masks. Methods The Fit test of 3 kinds of masks for registered emergency personnel in Shanghai was conducted by using the TSI Pro + 8038 tester. Results A total of 1 133 people were tested,and the pass rate of Real-time test was 93. 91%. 69 of them did not pass,while 310 did not pass the Fit test of all kinds of masks,and the pass rate of test was 72. 64%. Only 66. 55% of the tested masks could meet the needs of public health emergency personnel. The pass rate of Fit test of 3 imported brand masks for public health emergency personnel was21. 45%,38. 75%,and 9. 4%. Conclusion The types of medical masks for public health emergency in Shanghai are slightly inadequate. The risk of air leakage during use is the greatest,and the effectiveness of emergency protective masks should be further verified.
