The Relationship of Partial Pressure of Carbon Dioxide (PaCO₂) with Disease Severity Indicators Such as BODE and GOLD in Hospitalized COPD Patients

Figure 1

Comparisons of PaCO₂ according to the BODE and GOLD index, FEV₁%, and the distribution of BODE, GOLD, and SGRQ index according to the PaCO₂ median in COPD patients. (a) PaCO₂ levels of COPD patients according to BODE,  = 0.004. (b) PaCO₂ levels of COPD patients according to GOLD,  = 0.001. (c) FEV₁% of COPD patients according to PaCO₂ median,  < 0.001. (d) The proportion of COPD patients with high BODE scores according to PaCO₂ median,  = 0.030. (e) The proportion of COPD patients with high GOLD scores according to PaCO₂ median,  = 0.002. (f) The proportion of COPD patients with high SGRQ scores according to PaCO₂ median,  = 0.030.
