It was only the first of six emergency calls that day made by nursing home staff members over three and a half hours. By the final call, multiple paramedics were on the scene, as well as staff members who had walked over from Memorial Regional Hospital, a short distance away, and were alarmed by the conditions of the patients who had begun to arrive into their emergency room with heat stroke and fevers upward of 109 degrees.

The audio of the emergency calls, released by the Hollywood Police Department on Monday, gives a sense of the growing crisis that unfolded at the nursing home, Rehabilitation Center at Hollywood Hills. Eight residents, including Ms. Hibbard, died that day and six more died in the days and weeks that followed. More than 100 people were evacuated to hospitals and other nursing homes.

The callers, sometimes nurses or nursing assistants, attempted to remain calm, but often sounded pressured, exhausted and overwhelmed as they answered questions about the conditions of the patients. All were reported to be having severe difficulty breathing.

“Oh my God, this is crazy,” a woman making the fourth call said at around 6:15 a.m. as she struggled to find a patient’s age in the nursing home’s computer system, which had a separate power source. “We are initiating CPR at this moment,” she said. Then, sounding flustered, she gave the phone to another woman.

“They have a crash cart there, they’re working on her now as we speak,” the second woman said, referring to the wheeled supply cart used for resuscitations.
