At Huntington Memorial Hospital in Pasadena, California, nurses that usually care for one or two patients are now caring for three or four, infectious disease specialist Dr. Kimberly Shriner told CNN on Sunday.

“We have a limited number of ventilators, we have a limited number of ICU beds,” Shriner explained, adding that a team including a bioethicist, a community member, a physician, a nurse and an administrative leader will decide how to divide those resources if it comes down to it.

“If you don’t have respirators, you don’t have nurses to care for patients, you don’t have ICU beds, we will have to have these terrible discussions with families, which is why people need to stay home, and when they go out, they need to wear a mask,” Reiner said.

Martin Luther King Jr. Hospital will not turn patients away, Batchlor said, but staff may have to employ techniques that have been used in war.
