Fig 1 LA95% between the measured and predicted magnitude of changes in PaO2 for (a) the new formula, (b) the PaO2/FIO2 ratio formula, and (c) the PaO2/PaO2 ratio formula (n=173). The dotted lines represent the bias and LA95% between the measured and predicted magnitude of change in PaO2.

Fig 2 LA95% between the measured magnitude of change in PaO2 and that predicted by recruited RTs using (a) the new formula and (b) the isoshunt diagram (n=20). The dotted lines represent the bias and LA95% between measured and predicted magnitude of changes in PaO2.
