The Effect of Positive End Expiratory Pressure on Central Venous Pressure Among Patients With Different Lung Compliance

Not Applicable

• Conditions: Sepsis; ARDS; Traumatic Brain Injury
• Interventions: Other: 5,10 and 15cmH2O positive end expiratory pressure

• Registration Number: NCT03341572
• Lead Sponsor: Jingyuan,Xu

Brief Summary

To observe the effect of PEEP on CVP among patients with different respiratory compliance

Detailed Description

30 patients with mechanical ventilation and inserted central venous line will be entered. After gathering demographic data, patients undergone 5,10 and 15cmH2O PEEPs and the respective CVPs of the mentioned points will be recorded. According to the change of CVP, the patients will be divided into high response group and low response group, then comparing the lung compliance and thorax elastic resistance differences between the two groups.
