As the coronavirus pandemic grows, hospital supplies at Southern California’s Cedars-Sinai Health Systems are day to day, according to the hospital's chief operating officer.

“It is hard to estimate because we are consuming more than we would baseline,” Dr. Jeff Smith told CNN.

Cedars-Sinai typically treats more than a million patients each year in more than 40 locations throughout the greater Los Angeles area.

Smith said that Cedars-Sinai continues to receive supplies but the supply chain is irregular. They are obtaining personal protective equipment from multiple sources – manufacturers, local and federal caches.

“The challenge is that there are so many unknown variables,” Smith said speaking about the ratio of patients to supply. He said this is not the way he would want things because it is “day by day.”

Some context: Currently, Cedars-Sinai is seeing an increase in the volume of patients presumed and confirmed positive. “Several dozen” patients have now turned positive, Smith said.

Cedars-Sinai currently has enough ventilators for their patients in intensive care.

As for capacity, Cedars-Sinai has more than 200 open beds including in the ICUs. The hospital system is making plans to care for patients in less conventional spaces, including recovery units and other areas of the hospital.
