What is the normal range for Fraction of Inspired Oxygen (FIO2) in mechanical ventilation?

The normal range for the Fraction of Inspired Oxygen (FIO2) in mechanical ventilation is from 0.21 to 1.0. This range indicates the concentration of oxygen being delivered to a patient and is crucial for managing respiratory support in critically ill patients.

In this context, a value of 0.21 reflects room air, which is the baseline oxygen concentration humans typically breathe. On the other end of the spectrum, a value of 1.0 indicates that the patient is receiving 100% oxygen. This range allows clinicians to adjust oxygen levels according to the specific needs of the patient, depending on their condition and response to treatment.

Utilizing FIO2 appropriately is essential in preventing both hypoxia and oxygen toxicity, which can occur if patients receive inappropriate concentrations of oxygen for extended periods. Therefore, understanding and applying the correct normal range is vital for the effective management of patients requiring mechanical ventilation.
