Abstract: An embodiment of a single use nitrous oxide solution delivery system can be used in a prehospital setting such as in ambulances. A container can be filled with a predetermined relative concentration of nitrous oxide and oxygen gases. The container is sized to be stored in a repository within an automated dispensing cabinet (ADC) for medications. The container is connected to a regulator which includes a main control dial configured to allow a health care provider to adjust the volumetric flow rate of the nitrous oxide and oxygen gas mixture used by a patient. A scavenger can be optionally connected to a patient's mask and configured to remove exhaled gas. Another embodiment of a single use nitrous oxide solution delivery system can be used within hospitals and other medical buildings.
