How does dad send a circle of friends when he enters the intensive care unit?

If you want to send it, you can send a photo of the door of the intensive care unit and pray that dad is all right.

Intensive care unit, also known as ICU, is a ward that provides isolation places and equipment for patients with serious illness or coma, and provides services such as best care, comprehensive treatment and early postoperative rehabilitation. Mainly to treat critically ill patients who need close monitoring. These patients need to be closely monitored and provided with all kinds of support, such as respiratory and circulatory support, in order to provide patients with the best treatment time and opportunity and provide a platform for multidisciplinary cooperation. Intensive care unit is divided into pediatric intensive care unit, neonatal intensive care unit, medical intensive care unit, cardiovascular intensive care unit, emergency intensive care unit and neurosurgical intensive care unit.

Because ICU provides many services for critically ill patients, it has strict requirements on environmental disinfection, and can't enter casually like ordinary wards, and it stipulates the visiting hours of patients' families, and can only visit at fixed times.
