What should be done to control respiratory alkalosis linked with increased ventilatory drive?

• A. Increase tidal volume
• B. Switch to constant pressure mode
• C. Identify and correct the cause of increased drive
• D. Increase PEEP settings

Answer: (C)

To control respiratory alkalosis associated with an increased ventilatory drive, it is essential to identify and correct the underlying cause of the increased respiratory rate or depth. Respiratory alkalosis typically occurs when a patient hyperventilates, resulting in decreased carbon dioxide levels in the blood. This can be caused by various factors, such as anxiety, pain, metabolic disturbances, or hypoxia. By addressing these underlying factors, the ventilatory drive can be normalized, which will help restore the acid-base balance without the need for additional modifications to the ventilator settings. While adjusting ventilator settings, such as increasing tidal volume, switching modes, or modifying PEEP, might temporarily alter ventilation parameters, they do not address the root cause of the increased respiratory drive. Therefore, simply managing the symptoms without eliminating the cause may not effectively resolve the respiratory alkalosis. Understanding and tackling the primary issue ensures a more comprehensive treatment approach.
