RRS, residual sum of squares; Q̇ shunt, percent of cardiac output to regions of shunt (V̇A/Q̇ < 0.005); V̇ Dead, fraction of ventilation to dead space (V̇A/Q̇ > 100); mean Q̇, the mean of the perfusion distribution; LogSDQ̇, the standard deviation log scale of the perfusion vs. V̇A/Q̇ distribution, an index of V̇A/Q̇ heterogeneity; mean V̇ the mean of the ventilation distribution, LogSDV̇ the standard deviation log scale of the ventilation vs. V̇A/Q̇ distribution, an index of V̇A/Q̇ heterogeneity.
