4. Can I drive my car after my dental visit?
   
   
5. Are there any risks involved with the use of nitrous oxide?
   
   
6. Do any of my medical conditions indicate I should not receive nitrous oxide?
   
   
7. Will any medications I’m currently taking interfere with nitrous oxide?
   
   
8. How will I feel when I take nitrous oxide?
   
   
9. How will you be able to tell that I have reached an ideal state of sedation?
   
   
10. What types of feelings or sensations may indicate I am receiving too much nitrous oxide (or not enough oxygen)? When should I report this to you?
