The desk phone rang. Behind the glass partition that separated triage from the rest of the bay, a charge nurse in navy scrubs appeared as if conjured by the change in air pressure. Rita Chen was forty-one, black hair in a clip, posture that said she had already survived three minor disasters before midnight and expected a fourth before dawn. She took one look at Devin's chest wall and another at Alana's face, and the look she gave Nora was brief enough to be polite and sharp enough to be a verdict.
"Pulse ox. Now," Rita said.
Nora reached for the portable monitor with a motion that was professional and too slow at the same time, the delayed reflexes of someone whose first instinct had been procedure instead of person. The clip found Devin's small finger. The machine thought. Beeped. Thought again, as if even electronics needed a second to believe what they were about to announce.
Eighty-one percent.
Then seventy-nine.
A sound went through the waiting room that was not quite a gasp and not quite silence—the collective intake of people revising what they thought they had been watching.
"Peds. Respiratory. Now," Rita said into her radio, voice flat with command. "Bay triage, pediatric respiratory distress, sats in the seventies. Mother present. Moving to resus."
Alana felt her knees threaten to unlock and locked them anyway. She had known the number before the machine said it. Knowing did not make hearing it easier. Numbers were supposed to be tools. Tonight they felt like a courtroom.

"I was going to—" Nora began.
