Shunt and right shift of the arterial oxygen saturation versus partial pressure of inspired oxygen curve, R², for the fit to the model and ventilation:perfusion ratio

Infant	Shunt (%)	Shift (kPa)	R²	Shunt (%) 95% CI	Shift (kPa) 95% CI	V_A:Q
V_A:Q, ventilation:perfusion ratio.
The results for infants 5, 8 and 18 were derived manually and do not therefore have CI or R² values.
