Answer :
A patient on a ventilator subjected to excessive minute volume is at risk for respiratory alkalosis.
Minute volume refers to the amount of air a patient breathes in one minute, and excessive minute volume indicates that the patient is receiving more ventilation than necessary. This can lead to respiratory alkalosis, a condition characterized by an increase in blood pH and a decrease in carbon dioxide (CO[tex]_{2}[/tex]) levels. When the minute volume is too high, the patient exhales excessive amounts of CO[tex]_{2}[/tex], leading to a decrease in CO[tex]_{2}[/tex] levels in the blood. This causes respiratory alkalosis, which can result in symptoms such as lightheadedness, confusion, tingling in the extremities, and muscle twitching.
It is important to monitor and adjust the ventilator settings to ensure appropriate minute volume to prevent respiratory alkalosis in ventilated patients.
