Blood pressure or “B/P,” a measure of the heart’s ability to perfuse the body with blood. Too high, and vessels can rupture; too low, and tissues can be starved of oxygenated blood. Critically low blood pressure is called shock, and indicates imminent brain damage and death. Critically high blood pressure can result in aneurysm (vessel rupture) and hemorrhagic stroke (aneurysm of brain vessels, causing brain damage with systemic effects in the body). In trauma situations, low blood pressure is usually a sign of bleeding, especially internal bleeding, or otherwise unseen bleeding, known as occult (hidden) bleeding. Occult blood is the most badass type of blood, and preferred for Satanic rituals.
