• Patient Environment IEC 60601-1-1
Sub clause 2.204
Such an area is an environment in which medical diagnosis, monitoring or treatment is carried out.
It is very difficult to attach unique dimensions to the PATIENT ENVIRONMENT. In practice a
distance of 2,5 m (8.2 ft.) above the floor on which the medical personnel stand and a horizontal
distance of 1,5 m (4.9 ft.) have justified themselves as indicative of the dimensions of the Patient
Environment. The patient environment/vicinity is depicted as a dashed line in this procedure - see
the example in
Figure 1-1 .
• Patient Environment EN 60601-1
Sub clause 3.79 - Patient Environment
It is difficult for this standard to define dimensions for the volume in which diagnosis, monitoring or
treatment occurs. The dimensions for the PATIENT ENVIRONMENT given in
Figure 1-2 have been
justified in practice.
