About this study

The goal of this clinical trial is to evaluate if neural pressure support ventilation is able to improve patient-ventilator synchrony, in ICU patients undergoing non-invasive ventilation (NIV). The main question it aims to answer is:

  • Is neural pressure support ventilation better than the pressure support ventilation with respect to patient-ventilator synchrony during helmet NIV?

Researchers will compare neural pressure support ventilation versus pressure support ventilation (Gold standard assisted mode in Europe) to see if the new mode improve patient-ventilator synchrony.

Read the detailed description

Non-Invasive Ventilation (NIV) has found many different uses in clinical settings, shortening intubation times and preventing orotracheal intubation. NIV success is highly affected by patient comfort and patient-ventilator synchrony. The helmet is one of the most comfortable interfaces, even if synchrony is low due to dead space. The use of Neurally Adjusted Ventilatory Assist (NAVA), in which the Electrical Activity of the Diaphragm (EAdi) drives the ventilator, has shown improvement in comfort and synchrony but still some limitation with helmet, due to the long pressurization time. Pressure-Support Ventilation (PSV) is still the most used and diffused assisted mode in Europe due to its simplicity and effectiveness in helmet-NIV. The aim of this study is to test a new ventilation software called Neural Pressure Support Ventilation (nPSV), which merges the rapid pressurization of PSV along with the EAdi trigger, onto a population of 24 critical care patients ventilated with a helmet NIV.

Model description
Patients will be ventilated in nPSV or PSV (according to randomization) and then, after an initial period of ventilation, they will be ventilated with the other technique. Ventilation then will be optimized by an expert and the two modes of ventilation will be repeated in succession.
