Cold Sweat (1970)
James Mason: Captain Ross
Captain Ross : This is a stomach wound; stomach wounds bleed internally.
Katanga : I know what a stomach wound is!
Captain Ross : Do you know how many pints of blood a man has? He has ten pints, and mine's pumpin' out, slowly but steadily, at an estimated rate of four pints per hour. Therefore, in another hour, I will have lost consciousness and finally "check out."
