Stunning blue topaz, tourmaline, and red spinel jewelry has graced royal collections and red-carpet events. Today, only four gems bear the precious label: diamonds, emeralds, rubies, and sapphires; that was not always the case. The concept of precious and semi-precious gems is a fluid one.
Respiratory alkalosis is a medical condition in which increased respiration elevates the blood pH beyond the normal range (7.35-7.45) with a concurrent reduction in arterial levels of carbon dioxide. During acute respiratory alkalosis, the person may lose consciousness where the rate of ventilation will resume to normal. 2  Chronic respiratory alkalosis is a more long-standing condition. 3  For every 10 mmHg drop in PCO 2 in arterial blood, there is a corresponding 5 mEq/L drop in bicarbonate ion.
Alkalosis is a condition in which the body fluids have excess base (alkali). This is the opposite of excess acid (acidosis). The kidneys and lungs maintain the proper balance (proper pH level) of chemicals called acids and bases in the body. Decreased carbon dioxide (an acid) level or increased bicarbonate (a base) level makes the body too alkaline, a condition called alkalosis.
