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.
Metabolic alkalosis is diagnosed by measuring serum electrolytes and arterial blood gases. If the etiology of metabolic alkalosis is not clear from the clinical history and physical examination, including drug use and the presence of hypertension, then a urine chloride ion concentration can be obtained.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.
