Rush temporarily loses air conditioning, forcing the ER to go on bypass and appointments to be canceled

Rush University Medical Center experienced a temporary loss of air conditioning Monday morning, spokesperson Tobin Klinger said. Because of this, the hospital’s emergency room was put on bypass, meaning that ambulances in the area were instructed to bring patients to other hospitals, and many operating room procedures were canceled.

On Monday morning, a chilled water line in the Center’s Tower building went down. While the damage was repaired quickly, it created a delay in cooling that drastically affected the HVAC system and other equipment.

“Conditions in the Tower are expected to be uncomfortable until the cooling system can fully recharge. Steps are being taken to keep patients and staff safe as temperatures rise,” Klinger said. The hospital expects conditions to return to normal later today, and that the hospital is contacting patients directly to reschedule any canceled procedures.

Chicago is currently under a heat advisory, according to the National Weather Service, with the heat index expected to peak at 102 degrees.

Rush is not the first Chicago area hospital to struggle with keeping cool this summer. In June, Weiss Memorial had to evacuate its patients after an air conditioning failure that lasted over two weeks.
