AB  - KEY  POINTSSelecting  the  optimal  oxygen  delivery  system  will  depend  on  both  individual  patient  factors  such  as  oxygen  requirements,  patient  physiology,  and  device  tolerance  and  structural  factors  such  as  the  location  of  care,  device  availability,  and  patient  monitoring  capabilities.Given  the  consequences  of  both  hypoxemia  and  hyperoxemia,  oxygen  should  be  prescribed  to  achieve  a  target  saturation  such  as  oxygen  saturation  of  94%  to  98%  for  most  acutely  ill  patients,  with  a  lower  goal  of  88%  to  92%  being  preferred  in  patients  with  chronic  hypoxemia,  chronic  obstructive  pulmonary  disease,  or  other  risk  factors  for  hypercapnia.Low-flow  oxygen  devices  deliver  oxygen  at  a  flow  rate  below  that  of  the  patient’s  inspiratory  demand,  resulting  in  the  precise  delivered  FiO2  being  dependent  on  the  oxygen  flow  rate,  patient  inspiratory  effort,  device  fitment,  and  amount  of  entrained  room  air.High-flow  oxygen  devices  deliver  total  gas  flow  rates  exceeding  the  patient’s  inspiratory  demand,  delivering  a  mixture  of  oxygen  and  air  in  a  specified  ratio  at  a  precise  FiO2  independent  of  external  factors.High-flow  oxygen  devices,  in  addition  to  systems  that  bypass  the  upper  airway,  require  humidification,  which  is  most  frequently  accomplished  with  heated  humidifiers  or  heat  and  moisture  exchangers.
