NCT04844892

Brief Summary

The Lungpacer PROTECT Diaphragm Pacing Therapy System (DPTS) is a temporary, percutaneously-placed, transvenous, phrenic nerve-stimulating device intended to stimulate the diaphragm to preserve and improve inspiratory muscle strength in mechanically ventilated patients. The purpose of the PROTECT DPTS is to improve gas exchange, regional lung ventilation, and hemodynamics, and decrease atelectasis in patients presenting with acute respiratory distress syndrome (ARDS).
