Not necessarily, although its symbol is the water carrier, Aquarius is an AIR sign.  The water in Aquarius is symbolic of knowledge, especially spiritual.  Swimming in water â¦ is using it for a different purpose to, e.g. carrying it in a container.
Autoregulation is a process within many biological systems, resulting from an internal adaptive mechanism that works to adjust (or mitigate) that system's response to stimuli. While most systems of the body show some degree of autoregulation, it is most clearly observed in the kidney, the heart, and the brain. Perfusion of these organs is essential for life, and through autoregulation the body can divert blood (and thus, oxygen) where it is most needed. 1 Cerebral autoregulation.
ACLS and Epinephrine. Epinephrine is the primary drug used in the cardiac arrest algorithm. It is used for its potent vasoconstrictive effects and also for its ability to increase cardiac output. Epinephrine is considered a vasopressor. Indications for ACLS. 1  Vasoconstriction effects: epinephrine binds directly to alpha-1 adrenergic receptors of the blood vessels (arteries and veins) causing direct vasoconstriction, thus, improving perfusion pressure to the brain and heart. 2  Cardiac Output: epinephrine also binds to beta-1-adrenergic receptors of the heart.
