When does cyanosis become visible?
Typically, when the level of deoxygenated hemoglobin is around 3 to 5 g/dL, cyanosis becomes very evident. The presence of jaundice, skin color, ambient temperature, or light exposure might affect the assessment of cyanosis[7]. Anemia or polycythemia also plays a role in cyanosis.
