NADA BASOUDAN is an academic who published a paper in 2015 entitled Respiratory muscle oxygenation and myoelectrical manifestations during normoxic and hypoxic inspirat. NADA BASOUDAN published this work as part of a team: Basoudan, Nada. Here is a description of this work: Obj,,ctives: To examine the acute effect of hypoxia and inspiratory threshold loading (ITL) on (1) oxygenation of inspiratory muscles (sternocleidomastoid [SCM], scalene [SA] and parasternal [PS]) and, (2) electromyography (EMG) of the SA and SCM in healthy adults using near-infrared spectroscopy (NIRS) and linear array EMG respectively. Methods: Twenty healthy adults (12M/8F) were randomly assigned to perform two ITL tests while breathing a normoxic (Norm) or hypoxic (HYP, FIOâ‚‚=15%) gas mixture. NIRS devices were placed over the SCM, PS, SA, and a control muscle, tibialis anterior (TA), to monitor oxygenated (O2Hb), deoxygenated (HHb), and total hemoglobin (tHb) as well as tissue saturation index (TSI). SA and SCM activation were evaluated based on a normalized EMG amplitude, whereas fatigue was expressed as a decline in EMG.
