Fig. 2. A sample of zoning around the area of angiography room. The red dotted line indicates the area of no entry for other personnel (intermediate area). There should be only minimum number of staff participating. After transferring the patient on the table, only the operator (O) and the scrub in assistance (A) are allowed inside the highly contaminated area (inside the red line). The circulating nurse and the technician can enter the room if necessary but should be limited to the area of the dotted line. The yellow triangles with exclamation marks represent a sign displaying “COVID-19 area,” informing other personnel not to enter the area. The gloves and the surgical gowns must be removed properly before exiting the red line area. The area outside the red dotted line is considered as a “clean” area. When the structure of the angiography room area does not allow to create an intermediate zone, care must be taken not to contaminate equipment that cannot be disinfected easily. COVID-19: coronavirus disease.
