During general anesthesia, you usually require some form of a breathing tube, as spontaneous breathing often does not occur. Because your breathing reflexes, like coughing, are inhibited, you're at an increased risk of aspiration.

Why do they give you oxygen before anesthesia?

Abstract. Anesthesia is safe in most patients. However, anesthetics reduce functional residual capacity (FRC) and promote airway closure. Oxygen is breathed during the induction of anesthesia, and increased concentration of oxygen (O(2) ) is given during the surgery to reduce the risk of hypoxemia.

How does it feel being put to sleep?

Expect to be sleepy for an hour or so. Some people feel sick to their stomach, cold, confused, or scared when waking up. They may have a sore throat from the breathing tube. After you're fully awake and any pain is controlled, you can leave the PACU.

What do they put on your forehead during surgery?

EEG monitoring during surgery is carried out in about 2 per cent of hospitals in the UK, but only three or four electrodes are used, in a strip across the forehead. This looks at just one brain region, however, and so can only give you a probability of unconsciousness, not a conclusive answer, says Absalom.

Is it painful to be intubated?

Intubation is the process of inserting a breathing tube through the mouth and into the airway. A ventilator—also known as a respirator or breathing machine—is a medical device that provides oxygen through the breathing tube.
