ABG interpretation, ARDS severity, ROX index, QTc, BMI, BSA, biochem unit conversion, PEFR, and IV fluid composition reference.

H+ (nmol/L)

HCO3 (mmol/L)

Na+ (mmol/L)

K+ (mmol/L)

Cl- (mmol/L)

Glucose (mmol/L)

Urea (mmol/L)

Winter's formula: Expected pCO2 (mmHg) = 1.5 × [HCO3] + 8 ± 2. AG = Na+ + K+ - HCO3- - Cl-. mOsm = 2(Na+K) + Glu + Urea.
