The bias between the BAC and the BrAC in relation to the pCO 2 . (a) The underestimation of the BrACmeas as compared to the BAC is decreased with increased level of measured pCO2, which is achieved with increased length of expiration. (b) No bias and a more even distribution around the x-axis indicate a decreased influence from measured pCO2 with the use of BrACest.
