Put the mask on and fall asleep. Is anesthesia medicine in anesthesia mask?
The answer is no. In many patients' memories, the mask is closed and they fall asleep. But the truth is not that simple.
This situation is mainly seen in general anesthesia, anesthesiologist to the patient's mouth and nose buckle mask, and then let the patient breathe deeply, this time inhalation is not anesthesia, but a high concentration of oxygen, why is this?
Because the anesthesiologist is going to give you the anesthetic intravenously, and within a few seconds, you're going to fall asleep, unconscious, not breathing, relying on the oxygen stored in your lungs, the high concentration of oxygen that the anesthesiologist tells you to gulp in when he puts on the mask. The mask is connected by a tube to a ventilator, which ensures that the patient is getting plenty of oxygen.
When the endotracheal tube is successfully intubated, until the end of your surgery, this period is called the maintenance period of anesthesia, when you are not only inhaling oxygen, but also inhaling anesthesia from the anesthesia machine. This is to prevent the patient from waking up suddenly during the procedure.
Now general anesthesia, is generally used intravenous anesthesia and respiratory anesthesia combined, known as compound anesthesia.
