Achilleas Chytas, Katerina Vaporidi, Dimitris Babalis, Dimitris Georgopoulos, Nicos Maglaveras, Ioanna Chouvarda
2016 IFIP Advances in Information and Communication Technology  
Attention may be required in cases when patient's effort doesn't trigger the ventilator at all, and the assisted ventilation event is lost, i.e. when an ineffective effort (IE) event takes place.  ...  Intensive Care Unit (ICU) is a challenging environment, requiring continuous monitoring and treatment adaptations, raising the need for tools and platforms to support medical decisions.  ...  Afterwards, the user can select either of the two analysis pipelines currently in place, the feature extraction and/or the correlation between the ventilator recorded signals and their phase delay with  ...

2015 Medical and Biological Engineering and Computing  
Principal component analysis is employed for the transformation into a small number of features and the investigation of repeating patterns and clusters within measurements.  ...  Using these features, nonlinear prediction models based on support vector machines regression are explored, in terms of what past knowledge is required and what is the future horizon that can be predicted  ...  Other efforts included decision support in ICU ventilation actions and the control of mechanical ventilation.  ...
