Quizplus · Accepted Answer

Central cyanosis, which is the bluish discoloration of the skin and mucous membranes, is the most serious indication of decreased oxygenation as it is a sign of hypoxemia affecting the central circulation. Poor skin turgor, clubbing of the nails, and pursed-lip breathing are also possible signs of decreased oxygenation, but they are not as life-threatening as central cyanosis.
