Respiratory alkalosis
RAL:
Tissue carbon dioxide production is relatively constant. Respiratory alkalosis is therefore mainly caused by increased excretion of CO2 lungs. This reduces the pCO2 and thus the carbonic acid concentration in the system and deviates the ratio of bicarbonate and carbonic acid concentrations in the Henderson-Hasselbalch equation.
Causes
The cause of respiratory alkalosis is hyperventilation, which leads to hypocapnia:
- central breathing center stimulation- fear, pain, fever, pregnancy, trauma, head injuries, bleeding into the CNS, mental illness;
- peripheral respiratory center stimulation - pulmonary embolization (minor), congestive heart failure, high altitudes;
- liver failure with hyperammonaemia;
- G- sepsis;
- heart rhythm disorders;
- partial respiratory insufficiency, where efforts to maintain hyperventilation oxygenation lead to hypocapnia.
