transrespiratory pressure

trans·res·pir·a·tor·y pres·sure

(trans-res'pir-ă-tōr-ē presh'ŭr) The total pressure difference across the airways, lungs, and chest wall; the difference between the pressure at the airway opening (the mouth) and the pressure on the body surface (i.e., pressure at the airway opening - pressure at the body surface; equivalent to transairway pressure + transpulmonary pressure + transmural pressure).
