Fig. 2

Left panel: picture from one patient in ManoView showing the oesophagus with a red pressure curve created from pressure recording 1 cm apart along its full length. Numbers on the left side represents cm from the nostril. UES, upper oesophageal sphincter; LES, lower oesophageal sphincter. Middle panel: within a patient both positive (black arrow) and negative (red arrow) ΔPES may be seen during tidal inflation. Pressure curve recorded 2 cm apart 26–48 cm from the nostril. Right panel: both increases (black dotted arrow) and decreases (red dotted arrow) in end-expiratory oesophageal pressure may be seen when PEEP is increased. Pressure curves recorded 2 cm apart 27–49 cm from the nostril. Pressure recordings from representative patients
