Modified on Fri, 25 Jun, 2021 at 2:37 PM

TLco(Hb) = TLco * ((Hb_const + Hb) / (1.7 * Hb)) * (1.0 + 0.0035 * (PaO2 - 100)) * (1 / (1.02 - COHb/100))



Hb_const = 9.38 for women and children < 15 years

Hb_const = 10.22 for men > 15 years

Hb = entered Hb value default 13.4 for women and children < 15 years or 14.6 for men

PaO2 = entered PaO2 value default 100

COHb = entered COHb value default 2
