Abstract：
This mini-review provides the practice guideline recommendations for ventilation of remodeled negative-pressure isolation wards for COVID-19 Patients. Remodeled \"quasi-negative-pressure\" isolation wards had been proved a feasible, inexpensive, safe, and effective measure to contain nosocomial outbreaks. We should first determine the minimum required ventilation volume of an isolation ward based on the severity of COVID-19 patients. Mechanical ventilation remains the mainstay for achieving the requirement, while the assistance of recirculation is also helpful. Beyond adequate ventilation volume, the \"clean to less-clean\" directional airflow remains the golden rule for the solution of indoor ventilation. The virus-laden exhaust should be treated with HEPA/UV device or be kept away from living organisms, buildings, and air inlets.
摘要：
本小型综述提供了COVID-19患者重塑负压隔离病房通气的实践指南建议。改建的“准负压”隔离病房已被证明是可行的，便宜,安全,以及控制医院爆发的有效措施。我们应该首先根据COVID-19患者的严重程度确定隔离病房的最低通气量。机械通风仍然是实现这一要求的主体，而再循环的辅助也是有帮助的。超过足够的通风量，“干净到不干净”的定向气流仍然是解决室内通风的黄金法则。携带病毒的废气应使用HEPA/UV设备处理或远离生物体，建筑物,和进气口。
