A damaged-informed lung model for ventilator waveforms [PDF]
arXiv, 2020 The acute respiratory distress syndrome (ARDS) is characterized by the acute development of diffuse alveolar damage (DAD) resulting in increased vascular permeability and decreased alveolar gas exchange. Mechanical ventilation is a potentially lifesaving intervention to improve oxygen exchange but has the potential to cause ventilator-induced lung ...

Spatial features of CO2 for occupancy detection in a naturally ventilated school building [PDF]
Indoor Environments, Volume 1, Issue 3, 2024, 100018, ISSN
2950-3620Accurate occupancy information helps to improve building energy efficiency and occupant comfort. Occupancy detection methods based on CO2 sensors have received attention due to their low cost and low intrusiveness. In naturally ventilated buildings, the accuracy of CO2-based occupancy detection is generally low in related studies due to the complex ...

Clinical implication of monitoring regional ventilation using electrical impedance tomography
Journal of Intensive Care, 2019 Mechanical ventilation can initiate ventilator-associated lung injury (VALI) and contribute to the development of multiple organ dysfunction. Although a lung protective strategy limiting both tidal volume and plateau pressure reduces VALI, uneven ...

Robust Segmentation of CPR-Induced Capnogram Using U-net: Overcoming Challenges with Deep Learning [PDF]
arXivObjective: The accurate segmentation of capnograms during cardiopulmonary resuscitation (CPR) is essential for effective patient monitoring and advanced airway management. This study aims to develop a robust algorithm using a U-net architecture to segment capnograms into inhalation and non-inhalation phases, and to demonstrate its superiority over ...
