Effects of Inspiratory Flow Waveforms on Preload
NCT01892696 · Status: COMPLETED · Phase: NA · Type: INTERVENTIONAL · Enrollment: 60
Last updated 2016-11-09
Summary
The clinical usefulness of inspiratory flow pattern manipulation during mechanical ventilation remains unclear. The aim of this study was to investigate the effects of different inspiratory flow waveforms, i.e. constant and decelerating, on cardiac preload in mechanically ventilated patients assessed by arterial pulse pressure variation (PPV) and inferior vena cava distensibility.
Conditions
- Cardiac Output, Low
Interventions
- DEVICE
-
varying inspiratory flow waveforms
inspiratory flow waveform was changed, in a randomized sequence using a computer ,to one of the following modalities: 1) constant inspiratory flow; 2) decelerating inspiratory flow Each inspiratory flow waveform was maintained for 30 min. During the last 5 min of this period the physiological signals were collected and measures were performed.
