'Ventilation outage' delays surgeries at Chicago's Northwestern Memorial Hospital

Scores of surgeries were delayed or rescheduled at Northwestern Memorial Hospital after a fan malfunctioned in the operating room suites. Emergency and "essential" surgeries continued to be performed, but an unspecified number of elective or non-urgent procedures scheduled have had to be moved. The kinds of procedures that can wait would include hip or knee replacements or plastic surgery, hospital officials said.
