A-aDO2 

The EasyStat analyzer calculates the alveolar-arterial oxygen gradient 
according to the following equation

1

:

A-aDO2 = PAO2(TC) - PaO2(TC)

Alveolar oxygen partial pressure (PAO2(TC)) and arte-

rial oxygen partial pressure (PaO2(TC) = PO2(T)) are 

expressed at the patient corrected temperature. 

PAO2(TC) = (FIO2) (BP(TC)) - (PaCO2(TC)) (FIO2 + 1 - FIO2)
 

 

 

   R

where:    

A-aDO2 is expressed in mmHg 

  BP(TC) = Barometric Pressure - Vapor Pressure of water in mmHg
 

 

Vapor Pressure of water = 0.4 + antilog (0.0244T + 0.7659)

 

 

T = temperature in °C   

 

FIO2 = fraction of inspired oxygen

 

 

R = 0.8 = respiratory quotient   

PaO2(TC) = PO2(T)

The FIO

2

 value used is either the preset 21% or when entered, the 

value input from the 

PATIENT INFORMATION

 screen.

   

RI

   

The EasyStat analyzer calculates the respiratory index according to 

the following equation

1

:

 

RI  = A-aDO

Anion Gap

   

The EasyStat (chloride mode) analyzer calculates the Anion Gap 

according to the following equation

:

 ([Na+] + [K]) - ([HCO
