==High-flow Nasal Cannula==
*Different Setup to low-flow O2 therapy 
*Good for hypoxemic respiratory failure
*Every 10L/min is similar to 1mmHg PEEP
*Set flow and FiO2%
*Adults 
**Flow - start with 0.5 L/kg/min (Max 60L)
**FiO2 - start with 100% and taper down from there
*Pediatrics
**FiO2 - Start 40% and titrate up
**Flow - based on weight (table below) <ref>     Richards-Belle A, Davis P, Drikite L, et al     FIRST-line support for assistance in breathing in children (FIRST-ABC): a master protocol of two randomised trials to evaluate the non-inferiority of high-flow nasal cannula (HFNC) versus continuous positive airway pressure (CPAP) for non-invasive respiratory support in paediatric critical care     BMJ Open 2020;10:e038002. doi: 10.1136/bmjopen-2020-038002 PDF: https://bmjopen.bmj.com/content/bmjopen/10/8/e038002.full.pdf</ref>.

==Hyperbaric Oxygen (HBO)==
*Two methods of administration<ref name="Bitterman">Bitterman H. Bench-to-bedside review: Oxygen as a drug. Critical Care. 2009;13(1):205. doi:10.1186/cc7151.</ref>
*#Small, single-occupant chamber filled with 100% oxygen and pressurized to desired level
*#Large, multi-occupant chamber filled with room air and pressurized to desired level - occupants breathe supplemental oxygen at ambient pressure via mask
*Rationale for use<ref name="Bitterman" />
**At normal pressures (even with supplemental oxygen administration), very little oxygen is dissolved in plasma
**When oxygen provided at 3 ATA, there is enough oxygen dissolved in plasma to oxygenate all body tissues without resorting to hemoglobin-bound oxygen
