Surgery is a very common method in our modern medical treatment, and patients after major operations will be pushed to the intensive care unit for continuous oxygen inhalation and physical signs observation. So the question is, why do people who have undergone major surgery wear oxygen masks for oxygen after surgery? Is there not enough oxygen in the air for the patient to breathe? Next, the editor will give you some popular science on this issue. Friends who are interested should come and take a look.
First of all, people usually take "general anesthesia" measures when undergoing major operations, which means that the patient completely loses consciousness during the operation, and in this case, the patient has no control over instinctive breathing. Amnesia will also occur, so a tube will be intubated to deliver oxygen during the operation to ensure the body's demand for oxygen.
However, in order to activate the patient's lung function after surgery and enable the patient to breathe independently as quickly as possible, the supply and stimulation of external oxygen are needed. Low-flow continuous oxygen delivery can achieve this purpose. Oxygen can activate lung function as quickly as possible, allowing patients to wake up from respiratory amnesia under general anesthesia as soon as possible.
Secondly, it is to increase blood oxygen saturation. Blood oxygen saturation is a very important observation indicator after surgery. If the blood oxygen saturation continues to be low, it will cause irreversible damage to body functions and internal organs. During the operation, blood loss and respiratory forgetfulness will cause the patient's blood oxygen saturation. The blood oxygen level decreases, so in order to restore the blood oxygen index as soon as possible, postoperative oxygen inhalation is a necessary means.
In addition, general anesthesia for major surgeries will cause patients to fall into a coma for a period of time after surgery. In order to help patients wake up as soon as possible, oxygen inhalation is the best choice after surgery. Oxygen can help patients wake up as soon as possible. It is also helpful for observation of postoperative conditions.
The above are the reasons why people must wear oxygen masks to inhale oxygen after major operations. I believe everyone has seen this more or less in the hospital. How much do you guys know about postoperative oxygen inhalation? Welcome to leave a message to the editor to add information. Let’s popularize medical knowledge together.
