Key facts

• Nitrous oxide [VFr/PPres] Airway adaptor --during expiration
• Nitrous oxide^during expiration
• The IEEE 11073 Standards Committee does not distinguish between measures of gas concentration reported as partial pressure and volume percent because they can be converted from one to the other under the law of gases. To make it clear that these could be reported either way, LOINC presents the property for these terms as both a volume fraction and a partial pressure (VFr/PPres), with corresponding units of %{vol} and mm[Hg], respectively.
