Randomized CO2 level vs PE′CO2 presented for both normocapnia (35 mm Hg; a) and hypercapnia (50 mm Hg; b) groups. Exact values recorded from the E′CO2 monitor were presented red and randomized CO2 area appears in blue. The y-axis represents CO2 pressures (mm Hg), and the x-axis represents the record numbers for PE′CO2 values collected.
