TY - JOUR T1 - Dynamic near-infrared spectroscopy assessment as an important tool to explore pulmonary arterial hypertension pathophysiology JF - European Respiratory Journal JO - Eur Respir J DO - 10.1183/13993003.01932-2016 VL - 49 IS - 1 SP - 1601932 AU - Stavros Dimopoulos AU - Giorgos Tzanis AU - Andreas Karabinis AU - Serafim Nanas Y1 - 2017/01/01 UR - http://erj.ersjournals.com/content/49/1/1601932.abstract N2 - With great interest we read the recent article by Panagiotou et al. [1] in which the authors investigated the correlation between tissue oxygen measurements (StO2) at rest and during constant-workload exercise with the analogous measurements of mixed venous oxygen saturation at the level of pulmonary artery (SvO2) and inferior vena cava in patients with pulmonary arterial hypertension (PAH). In this study, the authors used near-infrared spectroscopy (NIRS) to assess the vastus lateralis muscle tissue oxygenation during exercise.Near-infrared spectroscopy: a useful methodology for pulmonary arterial hypertension http://ow.ly/7wwQ3065Cpb ER -
