Patients presenting with headaches need to be screened for primary vs secondary etiologies. “Red flags” associated with secondary headaches are crucial to identify. Physical examination should be completed with careful assessment of clues obtained during the history. It should include blood pressure measurements, assessment of mental status, and cranial nerve (CN) examination including but not limited to fundoscopic examination, gait, and facial strength.

Guidelines for the Clinical Use of Red Cell Transfusions
The red blood cell transfusions should not be dictated by a single hemoglobin “trigger” but instead should be based on the patient’s risks of developing complications of inadequate oxygenation. Red blood cell transfusion is rarely indicated when the hemoglobin concentration is greater than 10 g/dL and is almost always indicated when it is less than 6 g/dL.
