In the occasional cases of pneumonia which show a decrease in the oxygen capacity of the blood, the decrease is probably due to a formation of methemoglobin. The latter is removed from the circulation, however, as rapidly as it is formed, so that it can seldom be detected even qualitatively, and is probably never a cause of cyanosis.
在少数情况下，肺炎会导致血液氧合能力下降，这种下降可能是由于高铁血红蛋白的形成。然而，这种物质形成后会迅速从循环中清除，因此即使定性检测也很少能检测到，而且它可能从未引起过发绀。
