According to the equation of motion of the respiratory system, a ventilator can control all of the following variables except:

Question

Quizplus · Accepted Answer

The equation of motion of the respiratory system states that airflow is the product of change in pressure and conductance. Conductance is the reciprocal of resistance, which means that a ventilator can control resistance indirectly by manipulating conductance or airflow. Therefore, the correct answer is B) resistance, as it is not directly controlled by the ventilator. The ventilator can control volume, pressure, and flow by adjusting the tidal volume, inspiratory pressure, and flow rate, respectively.
