Answers: Commonly used inhaled anesthetics are nitrous oxide (also known as laughing gas), sevoflurane, desflurane, isoflurane and halothane. Each gas have its own special properties. For example, sevoflurane and halothane are easy to inhale while desflurane is highly irritating to inhale and has a shorter duration of endeavour. If you need to breathe yourself to sleep, halothane or sevoflurane would be easiest to inhale. If a awfully short-acting anesthetic is needed, the anesthesiologist can switch to desflurane after you fall asleep. Nitrous oxide is unforced to inhale, but when used alone is not potent enough to be a complete broad anesthetic. However, it can be used alone for sedation, or combined with one of the other inhaled anesthetics or injected soft anesthetics for general anesthesia.These gas have different effects on other organs as very well. For example, halothane may cause the heart rate to slow down and the blood pressure to halt while desflurane may cause the heart rate to speed up and the blood pressure to increase.
The most noteworthy gas we use is oxygen. Everybody gets oxygen. The other delivery service gases are medical nouns and nitrous oxide. Nitrous has anesthetic properties and comes on and go off outstandingly quickly (because of its low solubility within blood), but it is not potent enough to be used as a sole anesthetic.
The other gas we use are halogenated ethers. The ones in use today are isoflurane, desflurane and sevoflurane. There are reason to use or not use each gas, and I'm not going to jump into that here.
There are older gas that we don't use anymore. Halothane is one of those. It was adjectives we had for kids when I trained, but it cause a lot of heart rhythm problems, so I'm glad it's history. Other elderly gases include enflurane, cyclopropane, and methoxyflurane.
We use an anesthesia contrivance with vaporizers to deliver gas to patients:

All of our gas are color coded: you can see the 3 flowmeters on the left side of the apparatus - blue = nitrous, yellow = nouns and green = oxygen. The vaporizers are on the right: yellow = sevoflurane, purple = isoflurane and blue = desflurane.
The carter gases flow through the vaporizers and pick up doesn`t matter what concentration of gas we dial it to.
Isn't anesthesia fascinating? :)
