A podiatrist may use an oxygen-nitrous oxide mixture for sedation or analgesia only under the following conditions:

1. (1) the patient is not rendered unconscious;
2. (2) the nitrous oxide concentration is 70 percent of the mixture or less;
3. (3) the oxygen-nitrous oxide mixture is administered only by nasal inhalator equipped with scavenging system;
4. (4) an individual other than the attending podiatrist monitors the equipment and the patient during the administration of oxygen-nitrous oxide sedation and is medically directed and supervised by the podiatrist;
5. (5) the podiatrist and the individual referred to in clause (4) have successfully completed, after December 31, 1986, a course in nitrous oxide sedation approved by a school of podiatric medicine;
6. (6) the podiatrist and the individual referred to in clause (4) have completed, after December 31, 1986, a course in cardiopulmonary resuscitation;
7. (7) oxygen-nitrous oxide is not used in conjunction with any other analgesic or sedative; and

8. (8) the machine used for administering the oxygen-nitrous oxide mixture includes:

   1. (i) an automatic shutoff valve in the event the oxygen concentration is less than three liters per minute;
   2. (ii) an immediately available oxygen flush capability utilizing a positive pressure mask for pure oxygen delivery;
   3. (iii) an automatic control over maximum nitrous oxide concentration which prevents oxygen concentration from falling below 30 percent of the mixture when nitrous oxide flow is maximal; and
   4. (iv) color-coded valves, tanks, and knobs, and pin index and diameter index safety systems.
