It is an element of the [[Arterial blood gas (APACHE)]]. See http://en.wikipedia.org/wiki/FiO2 == Collection Instructions == There are special collection instructions for [[Arterial blood gas (APACHE)]], refer there for further info. FIO2 collection is impacted by this. Enter the FiO2 by choosing the type and LPM in the drop-down in [[CCMDB.accdb]]. Once entered, your choice will translate into a number. If you go back to the dropdown later to check what you have entered, ''the type/LPM may not be what you entered'', but they will be something that corresponds to the same percentage FiO2. In other words, you can not go back to this field later to see the type or LPM you entered originally. {{APACHE physiological variable |AP phys name= fraction of inspired oxygen |AP phys unit= percentage |AP phys absMax= 100 |AP phys warnMax= 100 |AP 0= as per [[AaDO2]] |AP phys warnMin= 20 |AP phys absMin= 20 }} == FiO2 dropdown == See drop-down in [[CCMDB.accdb]]. These FIO2's are '''estimates''' only that we use for the collection of arterial blood gas (ABG's) data for APACHE II scoring]] purposes. The actual FiO2 that a patient gets varies due to a number of factors that are not accounted for in these estimates. (breath rate and depth, distance of O2 diffuser from face, resistance to flow etc.) [https://bloggingforyournoggin.wordpress.com/2016/03/29/oxygen-flow-rate-and-fio2-understand-the-relationship/ Here is a link] for an article that deals with the relationship between FiO2 and flow rate. ===OptiFlow=== To get the FiO2 for optiflow * if available, use the optiflow or "high flow" when initiated by respiratory. * if that is not available, then as a default use the FIO2 you'd get with that oxygen flow with a regular nasal cannula == Implementation == The field draws its values from the [[S_FIO2 table]]. == Data Integrity Checks == {{Data Integrity Check List}} == Related articles == {{Related Articles}} [[Category:ABG]] [[Category:Standards and Conventions]]
