Patient-Ventilator Asynchrony: Occurence and Clinical Impact in Usual Care

The goal of this observational study is to unravel the occurence, impact and relations of Patient-Ventilator Aynchrony (PVA) in mechanically ventilated patients. The main questions it aims to answer are: * How often does PVA occur? * What are relations between clinical characteristics and PVA occurence? * What are relations between PVA occurence and patient outcomes? All questions will be assessed using data collected during the whole course of mechanical ventilation. Mechanically ventilated patients' medical data will be re-used. PVAs will be automatically classified on ventilator waveform data, using validated Deep Breath software.
