在一家正常运转的医院建立了一个30张床位的负压隔离病房。通过调整通风，相对于主要医院的压力为-29 Pa。在病房入口处未发生压力反向。病房内的压力略有上升。医护人员在病房应穿戴个人防护装备。在大规模空气传播传染病爆发期间，需要医院卫生保健服务的患者数量可能超过可用的负压隔离室容量。为了测试一种增加医院增援能力的方法，在一家功能齐全的医院建立了一个临时负压隔离病房。通过调整通风系统，在30张病床的医院病房中实现负压。在22个位置连续测量压差，并在整个病房的通风气流的特点。测试病房相对于主要医院走廊的压力平均为-29 Pa，比疾病控制和预防中心空气传播感染控制指南高出约10倍。在病房入口处没有发生压力反向，即使工作人员进入病房时也是如此。病房内的压力发生了变化，一些房间的压力变为中性或轻微正压。研究表明，建立临时负压隔离病房是提高医院应急能力的有效方法。
A 30-bed negative-pressure isolation ward was established on a functioning hospital. The pressure relative to the main hospital was −29 Pa by adjusting the ventilation. No occurrences of pressure reversal occurred at ward entrance. Pressures on the ward changed to slightly positive. Health care personnel should wear personal protective equipment on the ward. During a large-scale airborne infectious disease outbreak, the number of patients needing hospital-based health care services may exceed available negative-pressure isolation room capacity. To test one method of increasing hospital surge capacity, a temporary negative-pressure isolation ward was established at a fully functioning hospital. Negative pressure was achieved in a 30-bed hospital ward by adjusting the ventilation system. Differential pressure was continuously measured at 22 locations, and ventilation airflow was characterized throughout the ward. The pressure on the test ward relative to the main hospital hallway was −29 Pa on average, approximately 10 times higher than the Centers for Disease Control and Prevention guidance for airborne infection control. No occurrences of pressure reversal occurred at the entrances to the ward, even when staff entered the ward. Pressures within the ward changed, with some rooms becoming neutrally or slightly positively pressurized. This study showed that establishing a temporary negative-pressure isolation ward is an effective method to increase surge capacity in a hospital.
