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.
Background. Metabolic alkalosis is a primary increase in serum bicarbonate (HCO 3 -) concentration. This occurs as a consequence of a loss of H + from the body or a gain in HCO 3 - 2), which diminishes the change in pH that would otherwise occur.ydrogen ions may be lost through the kidneys or the GI tract. Vomiting or nasogastric (NG) suction generates metabolic alkalosis by the loss of gastric secretions, which are rich in hydrochloric acid (HCl). Whenever a hydrogen ion is excreted, a bicarbonate ion is gained in the extracellular space.
