Okay i might be retarded, but why i can’t understand that they r asking about the thing that is damaged ? 😂😂
Seriously! The question says "the goal of treatment is the protection of which of the following structures?" If too much O2 damages the retina, how is this treatment supposed to be protective to the retina?
I think too much oxygen would be with the ventilator having a high FiO2 setting, which they don't mention here but I'm guessing thats the thing they're controlling to avoid oxygen toxicity?
they didn't give the patient fio2 100%, question asks the reason for it. but in a very stupid way
Supplemental O2 may also cause bronchopulmonary dysplasia or intraventricular hemorrhage (germinal matrix, located in subventricular zone NOT choroid plexus)
92-95% isn't high, but it's enough to get everything else oxygenated. Because it's not 100% high flow the retinas don't over-vascularize and lead to damage/hemorrhage, and shit like that.
In other words....the question is basically asking why they gave the patient a fio2 of 92-95% instead of 100%. The reason is because 100% oxygen would lead to retinopathy of prematurity. The lower 92-95% oxygen levels protect the retina from damage. The wording of the question sucks tho imo.
