Through the partially open door in a treatment room in the E.R. of Sarasota Memorial Hospital, I look out at the cluttered counter of a nursing station.

Small colored sheets of paper are skewered on an upright thin spike. Wire baskets flow over with charts and graphs. A single thin brown folder totters at the edge of the counter, threatening to fall whenever a blue-clad nurse or aide shuffles or hurries by.

On my right in the small, darkened room, the machine next to me gives out a steady, slow series of beeps and a simultaneous series of blips, black dots of sound. The fluorescent lights in the corridor beyond the open door hum. Blips, beeps, and hums. A little night music complete with vocal accompaniment.

“Ron”-a woman’s voice, calm, weary-“glucose was two-five-two.”

A young man in short-sleeved whites wheels a gurney past the cubicle I’m in. Covered by a thin white blanket, an old man with eyes closed pauses just outside the room for an instant and then is pushed out of sight.

There is a low, calm chatter of voices, and then a heavy white nurse with glasses and close-cropped hair pushes a wheelchair past the door. A pretty young black woman sits in the chair, holding an infant.

“Four months old,” the young mother says. “She’s got asthma and something wrong with her heart.”

The heavy white nurse with glasses and close-cropped hair touches the young woman gently on the shoulder, and they roll by.

The passing parade pauses.

I look around the room. In the band of cold white light that comes through the open door, I see a gray stool and an overflowing ivory-colored trash can with the fingers of a blue rubber glove dangling out, as if someone or something is trying to escape.

There is a box on the wall, a see-through rectangular box with a plastic slot. The word “Danger” is printed in black letters on an orange square on the box and under it, also in black, “Used Needles.”
