[2025-09-29T19:10:42.077362] [PI reasoning] **Assessing nitrous oxide anesthesia**

I'm considering whether nitrous oxide can be used as a general anesthetic. It provides analgesia but has weak anesthetic potency since its MAC is over 100%, making it difficult to maintain adequate oxygen concentration at room pressure. Because of this, I can confirm that the main reason nitrous oxide isn't suitable as a sole anesthetic is due to hypoxia risk. I'll provide the answer as A: the difficulty in maintaining oxygen levels. I should look for citations to support this.
