Depends on what anesthetic you use. For an anesthetic which is really just an extreme pain reliever, they use a nitrous/oxygen which is sometimes called 'Laughing gas'. It is so called because in small doses it would give the patient a sensation of uncontrollable giggling fits.
To put someone to sleep they use the same gas but on a larger scale. The patient breathes it in voluntarily the they use a 'feeding tube' to deliver the gases straight to the lungs where they get immediately distributed to the blood streams.
Sometimes though they would use the liquid version of a general anesthetic first; evoflurane,Isofluruorane and halothane. Then they would use the other anesthetics afterwards.
Nitrous Oxide
Yes, typically desflurane, isoflurane, or sevoflurane are used.
nitrous oxide
Nitrous oxide gas is a colorless and odorless gas commonly known as laughing gas. It is used in medicine and dentistry as an anesthetic and analgesic. Additionally, nitrous oxide is sometimes used recreationally for its euphoric effects.

Nitrous oxide
This is a way too general question considering there are 100's of anaestics. Also, different types. Some more specific info would help.

Nitrous oxide
The property of gas used in supplying oxygen cylinders to hospitals is compressibility. Oxygen gas is compressed into cylinders at high pressure to store a large amount of gas in a small volume, making it easier to transport and distribute to hospitals for medical use.
Mainly pure oxygen is used, but this is often used in conjunction with nitrous, which has some pain- relieving properties and lowers the amount of actual anasthetic used. The drug that keeps the patient under anasthetic is vaporized into the o2/n2 mixture and therefore is breathed in by the patient.
