I am a nursing student and I have an evidence based research project to do. We were instructed to pick a topic/question about nursing interventions. I am having trouble finding the information I need so any help would be great!
I know doctors prescribe how much oxygen to administer to patients and it is generally a standard protocol for each unit. But I've noticed that for instance a pt. has a SpO2 of 88% and the nurse puts the patient on 2L of O2 per nasal canula. My question is: As a nursing judgement, how do you know how much o2 to administer based on the stats?
