Alkalosis

Classification according to ICD-10
E87.3	Alkalosis
ICD-10 online (WHO version 2019)

A alkalosis is a disorder of acid-base balance in humans and animals, an increase in the pH value in the blood causes. This means that the blood is more alkaline . If the pH value in the blood is above 7.45, it is called alkalosis. The normal value is pH 7.35 to 7.45. Below this limit one speaks of acidosis .

Classification

• A pH above 7.7 is usually fatal.
• The respiratory alkalosis caused by excessive exhalation of carbon dioxide at a hyperventilation of the patient. This can be psychogenic, a result of fear or a reaction to pain, or altitude-related (due to less oxygenated air), tetany and Rett syndrome .
• Reasons for a metabolic alkalosis can be loss of H ⁺ ions ( hydrons ) when vomiting acidic stomach contents, massive intake of alkaline substrates, such as sodium hydrogen carbonate , diuretic (urinary) therapy or disorders of kidney function . By definition, is a metabolic alkalosis before, when a too large excess of base ( base excess ) in the blood gas analysis is detected (a standard bicarbonate-value over 25 mmol / l).
