When administering oxygen, which of the following should be considered regarding oxygen toxicity?
1. It is only a concern with premature infants.
2. The longer the exposure, the worse the injury.
3. The higher the FiO2, the worse the injury.

a. 1 and 2 only
b. 2 and 3 only
c. 3 and 4 only
d. 2, 3, and 4 only
ANS: D
Administering high levels of supplemental O2 can cause lung injury as a result of O2 toxicity. Oxygen toxicity is considered to be time and dose dependent, that is, the longer the exposure and the higher the FiO2, the worse the injury. The RT must continuously titrate the FiO2 and PEEP to keep the target SpO2 in the range of 88% to 95%.
