Quizplus · Accepted Answer

Ventilatory capacity is influenced by the central nervous system (CNS) drive, which regulates the respiratory rate and volume, muscle strength, which determines the ability to generate the pressure necessary for ventilation, and muscle endurance, which affects the ability to sustain ventilation over time. Trigger level is not directly related to ventilatory capacity but rather to the sensitivity of the respiratory control system to initiate breaths.
