Understand the Problem
The question is asking which aspect of breathing control is limited in pressure support mode, which relates to respiratory management in clinical settings, particularly in ventilator support.
Answer
Rate and tidal volume.
In pressure support mode, the patient has no control over the rate or tidal volume.
Answer for screen readers
In pressure support mode, the patient has no control over the rate or tidal volume.
More Information
Pressure Support Ventilation (PSV) is a mode of mechanical ventilation where the patient has control over the initiation of breaths, but not over the tidal volume or the rate of breathing, which are influenced by the settings of the ventilator and the patient's effort.
Tips
A common mistake is confusing pressure support mode with other mechanical ventilation modes, like pressure control ventilation, where both rate and volume can be controlled.
