Calculate CO2 content of plasma via Douglas method

Description

douglas_plasma_co2_content_ml_dl calculates a hypothetical intermediary CO2 content of plasma via the method described by \insertCitedouglas_1988co2ntent.

Usage

douglas_plasma_co2_content_ml_dl(pco2, temperature = 37, ph = 7.4,
  inputs_are_kpa = TRUE)

Arguments

pco2	CO2 partial pressure
temperature	temperature in celcius. Default 37c
ph	pH (hydrogen ion concentration). Default 7.40
inputs_are_kpa	If TRUE, input pCO2 is in kPa, if FALSE use mmHg

Details

CO2 content of plasma is calculated from plasma temperature, pH, the calculated solubilty coefficient of CO2 in plasma and the apparent pK of the CO2-HCO3 equilibrium of plasma. The latter two parameters are calculated by co2ntent::co2_plasma_solubility and co2ntent::apparent_pk_co2_hco3.

The formulae published by \insertCitedouglas_1988co2ntent uses a factor of 2.226 to convert plasma co2 content to ml/dL. This is an interesting choice of molar volume, as it is inaccurate.

Value

The CO2 content of plasma in ml/dL
