Which of the following mechanisms explains the impaired renal function seen in patients receiving ventilatory support with positive pressure?
I.decreased secretion of aldosterone
II.decreased intravascular volume
III.increased secretion of vasopressin

Question

Quizplus · Accepted Answer

The impaired renal function seen in patients receiving ventilatory support with positive pressure is most commonly due to decreased intravascular volume, which can lead to decreased renal perfusion pressure and glomerular filtration rate. While increased secretion of vasopressin may also contribute to impaired renal function, decreased secretion of aldosterone is not typically a major factor in this setting.
