    • Accuracy of Medical Oxygen Flowmeters: A Multicentric Field StudyPeer reviewedOpen access 

      août 2014, DUPREZ, Frédéric; Barile, Maria; Bonus, Thierry; CUVELIER, Etienne; Ollieuz, Sandra; Mashayekhi, Shahram; Legrand, Alexandre, HE Condorcet
      Article scientifique
      The accuracy of 476 oxygen flowmeters was investigated using a thermal mass flowmeter in eight hospitals in France and Belgium. Different oxygen flow rates (2 to 15 l/min) were evaluated at the patient’s bed. When the sample was considered as a whole, the accuracy of delivered flow was acceptable but precision was poor. The variability of the delivered flow between devices was greater when a low ...

    • The double trunk mask improves oxygenation during high-flow nasal cannula therapy for acute hypoxemic respiratory failurePeer reviewedClosed access 

      30 avril 2019, Duprez, Frédéric; Bruyneel, Arnaud; Machayekhi, Shahram; Droguet, Marie; Bouckaert, Yves; Brimiouille, Serge; Cuvelier, Grégory; Reychler, Grégory, HE Condorcet
      Article scientifique
      High-flow nasal cannula (HFNC) oxygen therapy is used to deliver an FIO2 from 0.21 to 1.0. The double-trunk mask (DTM) is a device designed to increase the FIO2 in patients with a high inspiratory flow demand. The aim of our study was to evaluate the effect of DTM in hypoxemic subjects already receiving HFNC.

    • EEG-based brain-computer interface for alpha speed control of a small robot using the MUSE headbandPeer reviewedClosed access

      Non-invasive BMI applications are increasingly used in different contexts ranging from industrial, clinical and gaming. After having tested the difference between a classical EEG recorder with electroconductive gel (ANT system) and the MUSE EEG headband, we studied the BCI performances of the later during the control of a small robot. We demonstrated that the participants were able to successfully ...

    • Plasma asymmetric dimethylarginine concentrations are not related to differences in maximal oxygen uptake in endurance trained and untrained menPeer reviewedClosed access 

      22 novembre 2018, Pawlak-Chaouch, Mehdi; Boissière, Julien; Munyaneza, Désiré; Tagougui, Semah; Gamelin, François-Xavier; Cuvelier, Grégory; Heyman, Elsa; Goossens, Jean-François; Descat, Amandine; Berthoin, Serge; Aucouturier, Julien, HE Condorcet
      Article scientifique
      Asymmetric dimethylarginine (ADMA) is an endogenous inhibitor of nitric oxide (NO) synthesis that could limit oxygen (O2) delivery in the working skeletal muscles by altering endothelium‐dependent vasodilatation. Exercise capacity is associated with plasma ADMA concentrations in patients with cardiovascular diseases, but this issue has still not been investigated in healthy subjects. We aimed to ...

    • Thorpe tube and oxygen flow restrictor : what's flow accuracy ?Peer reviewedClosed access 

      10 février 2020, Duprez, Frédéric; Dubois, Adrien; Ollieuz, Sandra; Cuvelier, Grégory; Reychler, Grégory, HE Condorcet
      Article scientifique
      Oxygen gas flowmeters (OGF) are used to regulate the oxygen flow in acute and chronic care. In hospitals, Thorpe tubes (TT) are the classical systems most used for delivering oxygen. In recent years, the oxygen flow restrictor (OFR) has appeared. These devices use a series of calibrated openings in a disk that can be adjusted to deliver different flow rates. These devices have a reputation for ...
