Values are count (percentage) or mean ± standard deviation
CO2 responders to PP = patients in which PaCO2 decreases by at least 1 mmHg between end of PP session and before PP session. O2 responders to PP = patients in which PaO2/FiO2 increases by at least 20 mmHg between end of PP session and before PP session. O2 and CO2 responders to PP = patients in which PaO2/FiO2 increases by at least 20 mmHg and PaCO2 decreases by at least 1 mmHg between end of PP session and before PP session
