Excerpt
We read with interest the report by Karbing and coworkers [
1] in which they assess the clinical relevance of variation in the arterial oxygen tension (PaO
2)/fractional inspired oxygen (FiO
2) ratio, a widely used oxygenation index, alongside changes in FiO
2. In mechanically ventilated and spontaneously breathing patients, they showed that the clinical utility of PaO
2/FiO
2 ratio is doubtful unless the FiO2 level at which the PaO
2/FiO
2 ratio is measured is specified. They included data from 28 mechanically ventilated patients and from an additional eight mechanically ventilated patients at one or two different positive end-expiratory pressure (PEEP) settings. …
