摘要：

Estimation of intrapulmonary blood shunt fraction requires accurate evaluation of pulmonary capillary, arterial, and mixed venous oxygen contents. The presence of carboxyhemoglobin, as well as methemoglobin and sulfhemoglobin, may lead to large errors in the calculated intrapulmonary blood shunt fraction. The errors are most pronounced at low values of carboxyhemoglobin and low values of true intrapulmonary shunt fraction.
