Patients who are admitted to the ICU are generally in critical condition, with life-threatening and unstable vital signs. Whether a patient can be released from the ICU within 3 days depends on the patient’s condition, and there is no exact time point. The intensive care unit has a comprehensive monitoring system, including heart rate, blood pressure, electrocardiogram, blood gas analysis, body temperature, urine volume, all of which are monitored around the clock, so the patient’s life is relatively protected. Therefore, whether a patient with a serious disease, including coma and multi-organ failure, can be transferred to a general ward early after entering the intensive care unit is determined by the length of recovery. Generally, for some young patients with relatively good post-operative recovery and recovery from wakefulness, they can also be transferred to general wards in 3 days, but for most patients, intensive care units are generally rarely able to be transferred to general wards in 3 days.
