CMV operates by delivering a fixed volume or pressure of air to the patient's lungs at a set rate. This ensures that the lungs receive adequate ventilation even if the patient cannot initiate a breath on their own. The settings on a CMV machine are adjusted based on the patient's size, condition, and the underlying cause of respiratory distress. Understanding the mechanics of CMV helps epidemiologists in assessing the efficacy of ventilation strategies in different patient populations.
