[Combined effects of elevated body position on gastroesophageal reflux and intra-abdominal pressure in mechanical ventilated patients].
To investigate the combined effects of elevated body position on gastroesophageal reflux and intra-abdominal pressure (IAP) in patients undergoing mechanical ventilation (MV) who were receiving enteral nutrition, and to find out their proper height of head of bed. ⋯ Although elevation of the body position of MV patients can reduce gastroesophageal reflux, it also increase the IAP. When the body position is elevated to 45 degree angle, the number of reflux is not reduced effectively, while the rate of high esophageal reflux and the patients' IAP are increased significantly, indicating that 30 degree might be the proper body position for the MV patients receiving enteral nutrition.

[Effect of mechanical ventilation guided by transpulmonary pressure on hemodynamics and oxygen metabolism of porcine model of intra-abdominal hypertension].
To assess the effect of mechanical ventilation (MV) guided by transpulmonary pressure (Ptp) on hemodynamics and oxygen metabolism of porcine model of intra-abdominal hypertension (IAH). ⋯ There were remarkable effects on oxygen metabolism and Cst and less influence on hemodynamics in response to MV guided by Ptp. The results of this study are in favor of setting Ptp according to measurements of esophageal pressure in pigs with IAH.

[The change in strategy of mechanical ventilation: a single center study in China].
To observe the treatment strategy and its changes in mechanical ventilation (MV) in a single medical center. ⋯ The ventilator modes and settings had been changed in a single medical center in the past 10 years. It is speculated that the changes are related with the results observed in some multicenter randomized controlled trials (RCTs).
