Description
Viktor Erbring and colleagues chart how esophageal pressure, the stand-in for pressure around the lungs, behaves when ventilated patients lie face down versus face up. Their 2026 study uses high-resolution manometry, with sensors along the whole esophagus, in twenty patients measured before spinal surgery. Two levels of airway pressure support were tested in each position.
End-expiratory pressure ran lower in the prone position, while its swing with each breath grew larger and the heart's ripple on the trace shrank. Which sensors were averaged changed the numbers substantially, and within-patient variability ranged widely depending on settings. A hand-picked set of theoretically optimal sensors gave lower, steadier readings than broad regional averages. The authors warn that position, pressure level, and sensor choice all bend this measurement, complicating its use for setting lung-protective ventilation.
