Esophageal pressure monitoringTracheotomy tip pressure
Esophageal pressure monitoring: Esophageal pressure and Tracheotomy tip pressure were measured simultaneously in patients with off-line tracheotomy to verify the correlation

Study summary
Whether the correlation between gas incision tip pressure fluctuations (ΔPtt) and esophageal pressure fluctuations (ΔPes) is a potential measure of spontaneous respiratory effort in patients undergoing gas incision offline.
