Clarke, who has basic medical training, attempt to perform a blood transfusion without knowing neither the patients nor the donor's blood type. A transfusion of incompatible blood type would cause the death of the patient, the opposite of Clarke's aim.
However, there was no way of testing blood type, and this was the patient's only chance of survival. Therefore a blood transfusion did not increase the risk of death.

In the first shot of The Ark, the lens flare from the Sun is composited behind The Ark and Earth. But as lens flares occur inside the lens, the flare should always appear atop everything else. Additionally the Sun appears to move relative to the other stars in the background; from the perspective of Earth orbit, the Sun should appear stationary.
