Weaning And Variability Evaluation (WAVE) — WAVE  

Extubation Clinical Trial

Official title:
Weaning And Variability Evaluation

Clinical Trial Summary

The purpose of this study is to determine if variability in heart and breathing rates can be used to predict successful weaning. We are collecting data to determine whether or not subtle differences in heart rate and respiratory function will help physicians to decide if a patient is ready to be weaned.

Clinical Trial Description

In this prospective observational pilot study, mechanically ventilated patients weaning or near extubation (i.e. within 1-5 days) were selected to undergo continuous heart rate (EKG waveform at 500 Hz) and respiratory rate (expired CO2 waveform at 100 Hz) recording. The data was collected as per standard practice by the bedside monitor (Phillips Intelivue MP70). A portable CPU with TrendfaceTM software was used to download the data for variability analysis. All decisions on timing of SBTs and extubation were left to the discretion of the treating team who were unaware of the variability results. SBT's were repeated daily from trial onset until extubation patient permitting. ;
