What is the maximum level of FIO2 in the case below?
A male client with pneumonia develops respiratory failure and has a partial pressure of arterial oxygen of 55 mm Hg. Hes placed on mechanical ventilation with a fraction of inspired oxygen (FIO2) of 0.9.
If a male client with pneumonia develops respiratory failure with a partial pressure of arterial oxygen of 55 mm Hg he will be placed on a mechanical ventilator with a fraction of inspired oxygen (FIO2) of 0.9. In this case the goal goal for the nurses should be to reduce the FIO2 to no greater than a range of 0.18 to 0.21.
If an FIO2 is greater than 0.5 for even as little as 16 to 24 hours it can be toxic and result in decreased gas diffusion and surfactant activity. FIO2 is a fraction of oxygen that is enhanced to have a higher than atmosphere concentration of oxygen. This is vital for patients that are expereincing difficulty breathing.
