Physiologic Dead Space / Tidal Volume Ratio (Vd / Vt phy)

Range: 0 – 99%
Resolution: 1%
Alveolar Dead Space (Vd alv)
Range: 0 – 999 mL
Resolution: 0.1 mL or three significant digits (whichever is greater)
Oxygenation Index (OI)
Oxygenation index is a dimensionless number often used to assess the "pressure cost" of oxygenation.
OI Range: 0 – 200 (when PAO2 is entered in mmHg); OI Range: 0 – 1500 (when PAO2 is entered in kPa)
Resolution: 0.1 or three significant digits (whichever is greater)
