What range of PaO2 should be maintained in infants to minimize the risk of retinopathy of prematurity (ROP)?

50 to 80mmHg

Explanation:

Retinopathy of prematurity (ROP) is described as an ocular condition associated with O2 administration to premature infants. Excessive blood O2 levels produce retinal vasoconstriction, which (if prolonged) can result in permanent blindness. This risk poses a serious management problem, for the premature infant is often in need of supplemental O2. The American Academy of Pediatrics has recommended that keeping PaO2s between 50 to 80mmHg is the best way to minimize the risk of Retinopathy of Prematurity.

explanation:

venn diagram is pictorial representation with of circles showing the relation between two finite sets or things. the intersection part of two circles conveys the relation present in between those sets or things.

here in the venn diagram of sand and salt two circles represent sand and salt. but the area falling under the intersection of these circle represents the mixture of sand and salt.

so, in a venn diagram the mixture will be placed in a middle that is in between the intersection of two circles.
