Purpose

This study investigates how different degrees of muscular unloading during mechanical ventilation impact endurance of succeeding spontaneous breathing trials

Condition	Intervention
Chronic Respiratory Failure	Device: positive pressure ventilation

Study Type:	Interventional
Study Design:	Allocation: Randomized Endpoint Classification: Efficacy Study Intervention Model: Crossover Assignment Masking: Single Blind Primary Purpose: Treatment
Official Title:	Impact of Respiratory Muscle Unloading on Respiratory Muscle Endurance

Further study details as provided by Krankenhaus Kloster Grafschaft:

Primary Outcome Measures:

Endurance time

Secondary Outcome Measures:

PCO2, respiratory parameters

Estimated Enrollment:	10
Study Start Date:	December 2006
Estimated Study Completion Date:	June 2007

Detailed Description:

Liberation from mechanical ventilation in difficult to wean patients is best accomplished by intermittent spontaneous breathing trials (1). Optimal respiratory muscle rest in-between breathing trials however has never been investigated.

Using a crossover design, patients are to be ventilated with complete and partial respiratory muscle unloading for a period of ten hours respectively. Respiratory muscle activity is being monitored by oesophageal balloon technique using a commercially available System (Avea, Viasys, Conshohocken, PA, USA). Time of spontaneous breathing, respiratory- and ABG parameters are being determined to characterize the course of each spontaneous breathing trial.
