Effects of pressure-controlled and volume-controlled ventilation on respiratory mechanics and systemic stress response during prone position

Abstract

When compared with VCV mode, PCV mode is associated with lower P-peak and P-plateau levels during both supine and prone positions, better oxygenation postoperatively, lower blood cortisol levels during surgery in prone position and in the early postoperative period. We concluded that PCV mode might be more appropriate in prone position during anesthesia.
