[A study of esophageal function and reflux characteristics of gastroesophageal reflux disease in patients presenting with chronic cough].
To investigate the characteristics of gastroesophageal reflux disease (GERD) with chronic cough by the results of combined multichannel intraluminal impedance and high-resolution manometry (MII-HRM) procedure and 24-hour multichannel intraluminal impedance combined pH (MII-pH) monitoring. ⋯ Decrease of the UESP, increase of the reflux episode activity (acid/nonacid) in supine position and proximal reflux episode (nonacid) in supine position, lengthened mean bolus clearance time in supine position and the degraded esophagus clearance ability may all correlated with the pathogenesy of GERD with chronic cough.

[Dead space guided positive end-expiratory pressure in patients with acute respiratory distress syndrome].
To evaluate the value of dead space fraction (V(D)/V(T)) guided positive end-expiratory pressure (PEEP) in acute respiratory distress syndrome (ARDS). ⋯ V(D)/V(T) could be one of the methods to titrate the optimal PEEP in patients with early ARDS. Optimal PEEP targeting the highest compliance in conjunction with the lowest dead space fraction indicated a maximum amount of effectively expanded alveoli.
