Already the Babylonians connected this Zodiac sign and the constellation with the mythological animal, sort of a mermaid goat. They called it the Goat-Fish. The reason for this is hidden in history.
Without an adequate blood supply, the heart muscle is deprived of oxygen and nutrients and waste products manufactured by the cells accumulates in the muscle tissue. Depending on the severity, it may cause myocardial ischemia, which is damage but not death of the muscle due to an inadequate blood supply. Alternatively it may cause death of the muscle tissue which is known as a myocardial infarction (MI).
Oxygen saturation is a term referring to the fraction of oxygen-saturated hemoglobin relative to total hemoglobin (unsaturated + saturated) in the blood. The human body requires and regulates a very precise and specific balance of oxygen in the blood. Normal blood oxygen levels in humans are considered 95-100 percent.If the level is below 90 percent, it is considered low resulting in hypoxemia. Blood oxygen levels below 80 percent may compromise organ function, such as the brain and heart, and should be promptly addressed.Continued low oxygen levels may lead to respiratory or cardiac arrest.f the level is below 90 percent, it is considered low resulting in hypoxemia. Blood oxygen levels below 80 percent may compromise organ function, such as the brain and heart, and should be promptly addressed. Continued low oxygen levels may lead to respiratory or cardiac arrest.
