On a recent Friday afternoon, the critical care charge nurse at a South Los Angeles hospital tries to send another nurse off to grab lunch. Maria Arechiga is interrupted by the beeping of an alarm, the vitals of a patient declining, organs failing.
She dons a surgical gown and unzips a plastic tarp that hangs from the doorway of a hospital room — a makeshift isolation room on this floor temporarily transformed into a larger intensive care unit to make space for the patients that just keep coming. She slips inside.
