Paramedics in Southern California are being told to conserve oxygen and not to bring patients to the hospital who have little chance of survival, as Los Angeles County grapples with a new wave of COVID-19 patients that is expected to get worse in the coming days. The Los Angeles County Emergency Medical Services Agency issued a directive Monday that ambulance crews should only administer bottled oxygen to patients whose oxygen saturation levels fall below 90%. In a separate memo from the county's EMS Agency, paramedic crews have been told not to transfer patients who experience cardiac arrest unless spontaneous circulation can be restored on the scene.
