A male client with pneumonia develops respiratory failure and has a partial pressure of arterial oxygen of 55 mm Hg. He’s placed on mechanical ventilation with a fraction of inspired oxygen (FIO2) of 0.9. The nursing goal should be to reduce the FIO2 to no greater than:
a- 0.21
b- 0.35
c- 0.5
d- 0.7
Answer C.
An FO2 greater than 0.5 for as little as 16 to 24 hours can be toxic and can lead to decreased gas diffusion and surfactant activity. The ideal oxygen source is room air F IO 2 0.18 to 0.21.
