Generally speaking, patients need to give oxygen for about 6 hours after general anesthesia surgery, if the surgery is more complicated, the patient is weaker or involves the respiratory system oxygen time needs about 1~2 days, or even long-term oxygen.
Anesthesia effect does not disappear immediately after the end of surgery, respiratory function is not fully recovered, prone to blood oxygen drop. Therefore, patients usually need oxygen after general anesthesia surgery.
If the operation is relatively simple, less harm to the patient’s body, postoperative recovery is relatively fast, general general anesthesia after surgery routine oxygen for about 6 hours can be.
If the surgery is more complex, and may affect the lung function, resulting in patients with low oxygen saturation, should be appropriate to extend the oxygen time, usually need 1 ~ 2 days. In severe cases, endotracheal intubation operation is needed, and the use of ventilator-assisted oxygenation is necessary to ensure gas exchange in the patient’s lungs and long-term oxygenation.
It is recommended that patients must pay attention to keep the airway open after the operation, and pay attention to the time of oxygen intake and the flow rate of oxygen intake, so as to avoid any influence on the recovery of the condition.
