Problem based learning (Session I) Cyanosis
Cyanosis-Hints Central cyanosis:implies decreased arterial oxygen saturation Peripheral cyanosis:caused by a decreased rate of peripheral blood flow
Cyanosis-Hints ◼ Central cyanosis: implies decreased arterial oxygen saturation ◼ Peripheral cyanosis: caused by a decreased rate of peripheral blood flow
