Modified floor plan during the COVID-19 pandemic. The ED was sectioned into three main areas: high-risk (pink), moderate-risk (yellow), and low-risk (blue) areas. High-risk areas included an outdoor triage, a quarantine zone, a quarantine station, and an isolation area that was composed of an isolation zone, two isolated resuscitation rooms, and a room to don and doff PPE. The moderate-risk area included an indoor triage, a resuscitation zone and a critical-care zone for critically ill patients, an ambulatory emergency care zone, and an acute care zone. The low-risk area (blue) consisted of an observation zone, where patients with negative COVID-19 PCR tests awaited admission or further management, and rooms to don and doff PPE. The blue arrow shows a one-way path to reallocate patients from moderate-risk areas to low-risk areas. The green arrow shows the direction of the staff flow to don PPE. The red arrow shows the direction to doff PPE and leave the ED. The iPad in the quarantine zone was placed on an immobile tablet security stand (triangle), and two iPads were given to physicians in the resuscitation zone, ambulatory emergency care (AEC) zone, acute care zone, and observation zone (circles).
