Official title
Neural Pressure Support, a Randomized Crossover Trial
Overview
In this study patients who are intubated and on ventilator for more than 24h will be ventilated at three different level of support in Pressure Support and Neural Pressure Support to study patient-ventilator synchrony and muscle unloading.
Detailed description
This study is an interventional randomized crossover study in intubated and mechanically ventilated patients for more than 24h. Eligible patients from whom informed consent is obtained and Pes and Edi catheter are successfully positioned are enrolled in the study. Patients will be ventilated in Pressure Support and Neural Pressure Support at three different level of assist (baseline, 50% and 150% of baseline respectively) in randomized order. Ventilator curves will be recorded and bloodgas obtained at the end of each study step, each lasting 20min.
Interventions
- Device Neural Pressure Support (mode of mechanical ventilation)
Nasogastric tube will be removed and replaced by a Esophageal catheter and Electrical Diaphragm activity catheter and mechanical ventilation in mode Neural Pressure Support
Primary outcome measures
- Patient-ventilator asynchronies [Time frame: 20 minutes ventilatory traces recording]
Secondary outcome measures (1)
- respiratory muscle unloading [Time frame: 20 minutes ventilatory traces recording]
Eligibility criteria
Inclusion criteria
-Patients intubated for more than 24 hours in the weaning phase from the ventilator.

- unstable circulation (requiring high vasopressor dose, for example Noradrenalin >0,2µg/kg/min)
- severe lung disease (PFI ≤ 13,3 kPa)
- fever> 38,5°C
- pregnancy.
