How does Sidney Kingsley use imagery in Men in White?

Atmosphere is a key component of this play. Scenes are constantly punctuated with calls on the public address system, stage directions call for constant activity in the hallways, and there is a sense that conversations are conducted with speed, urgency, and terse clarity. There is also a great deal of authentic-sounding medical terminology and it's easy to see how Men in White might be described as the ER of its period. These elements provide the impression, not only of carefully researched realism, but also that what is going on is extremely important; reinforcing a key component of the play's central conflict that becomes more and more defined as the action unfolds.
