Minnesota Statutes 153.26 – Use of Nitrous Oxide
A podiatrist may use an oxygen-nitrous oxide mixture for sedation or analgesia only under the following conditions:
(1) the patient is not rendered unconscious;
(2) the nitrous oxide concentration is 70 percent of the mixture or less;
(3) the oxygen-nitrous oxide mixture is administered only by nasal inhalator equipped with scavenging system;
(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) 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) the podiatrist and the individual referred to in clause (4) have completed, after December 31, 1986, a course in cardiopulmonary resuscitation;
(7) oxygen-nitrous oxide is not used in conjunction with any other analgesic or sedative; and
(8) the machine used for administering the oxygen-nitrous oxide mixture includes:
(i) an automatic shutoff valve in the event the oxygen concentration is less than three liters per minute;
(ii) an immediately available oxygen flush capability utilizing a positive pressure mask for pure oxygen delivery;
(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
(iv) color-coded valves, tanks, and knobs, and pin index and diameter index safety systems.
