How does mechanical ventilation cause respiratory alkalosis?

Respiratory alkalosis is a disturbance in acid and base balance due to alveolar hyperventilation. The decrease in PaCO2 (hypocapnia) develops when a strong respiratory stimulus causes the respiratory system to remove more carbon dioxide than is produced metabolically in the tissues.Click to see full answer. In this regard, what is the main cause of respiratory alkalosis?Respiratory alkalosis occurs when you breathe too fast or too deep and carbon dioxide levels drop too low. This causes the pH of the blood to rise and become too alkaline. When the blood becomes too acidic, respiratory acidosis occurs.Also, how does the body correct respiratory alkalosis? The condition will likely resolve if a person or doctor corrects the underlying cause. The body may try to self-correct the pH imbalance that comes with respiratory alkalosis, such as by having the kidneys increase excretion of alkaline and reduce excretion of acid. Keeping this in view, how does hypoxemia cause respiratory alkalosis? Respiratory alkalosis involves an increase in respiratory rate and/or volume (hyperventilation). Hyperventilation occurs most often as a response to hypoxia, metabolic acidosis, increased metabolic demands (eg, fever), pain, or anxiety.How do you fix a respiratory alkalosis on a ventilator?Inadequate sedation and pain control may contribute to respiratory alkalosis in patients breathing over the set ventilator rate. In hyperventilation syndrome, patients benefit from reassurance, rebreathing into a paper bag during acute episodes, and treatment for underlying psychological stress.
