Quizplus · Accepted Answer

The supine position, malnutrition, and obesity can all decrease a patient's ability to generate a negative intrapleural pressure. The supine position can lead to a decrease in lung volume and diaphragmatic movement. Malnutrition can weaken respiratory muscles, and obesity can restrict lung expansion and diaphragmatic movement. Large tidal volumes on a mechanical ventilator do not decrease the ability to generate negative intrapleural pressure; instead, they are more related to ventilator settings and lung mechanics.
