==ABSTRACT==
Objective: To compare ideal PaO2
 with PaO2
 found, ideal PaO2
/FiO2
of room air with the one found, and ideal FiO2
 with FiO2
 found in
mechanically ventilated elderly patients. Methods: Cross-sectional
study that evaluated elderly mechanically ventilated patients for
at least 72 hours and who underwent three subsequent blood gas
analyses. Results: The sample consisted of 48 elderly with mean age
of 74.77±9.36 years. There was a significant difference between the
ideal PaO2
 and the one found (p<0.001), between FiO2
 corrected and
the offered one, and also between ideal PaO2
/FiO2
 of room air and the
PaO2
/FiO2
 found (p<0,001). Conclusion: A significant increase was
seen in PaO2 and FiO2 and in alterations of gas exchange by PaO2
/FiO2
index than those found in normal parameters.
