Layout and management of the surgical intensive care unit during the novel coronavirus infection epidemic period/ 新型冠状病毒感染疫情期外科重症监护室布局改造及管理

Objective To discuss the key points of reconstruction from the surgical intensive care unit (SICU) to the negative pressure isolation ward which can treat patients with novel coronavirus pneumonia (NCP) Methods The key points of the reconstruction are as follows: establishment of “three zones and two passages,” transformation of the ventilation system, process management of personnel access room, and introduction of the visual management concept Results The reconstructed surgical ICU can maintain the original space area As for space layout, there are separate clean zone, semi-polluted zone and polluted zone as well as a separate passage for patients and medical personnel respectively, without the two groups of people contacting each other To achieve positive air pressure in the clean zone, negative air pressure in the semi-polluted zone is -5Pa to -10Pa, and negative air pressure in the patient zone is -10Pa to -20Pa And we ensure that the pressure difference (negative pressure) in adjacent rooms with the same pollution level is not less than 5Pa Under normal circumstances, the pressure can be switched to positive one for admission of general ICU patients Conclusion Through the reconstruction, the SICU can meet the requirements of treatment of NCP patients The main points of reconstruction are space layout and the air conditioning and ventilation system
