Evaluation of a textile-based near infrared spectroscopy system in calf muscle oxygenation measurements


Nasseri, Nassim; Zysset, Christoph; Büthe, Lars; Kleiser, Stefan; Tröster, Gerhard; Wolf, Martin (2014). Evaluation of a textile-based near infrared spectroscopy system in calf muscle oxygenation measurements. Advances in Experimental Medicine and Biology, 812:355-360.

Abstract

We recently introduced a novel textile-based NIRS sensor (TexNIRS). Here, we evaluate TexNIRS in ten subjects (16 legs, age 28.5 ± 2.32 years, adipose tissue thickness (ATT) 4.17 ± 1.71 mm). Three venous occlusions at 50 mmHg were performed on their calf muscle. After 3 min of occlusion, oxy/deoxy hemoglobin concentration ([O₂Hb], [HHb]) changes were 3.71 ± 1.89/1.79 ± 1.08 μM; venous oxygen saturation (SvO₂) was 75 ± 9.7 %, oxygen consumption (VO₂) was 0.02 ± 0.01 mL/100 g/min, hemoglobin flow (HF) was 0.93 ± 0.48 μmol/100 mL/min, and blood flow (BF) was 2.01 ± 1.04 mL/100 mL/min. Our results are in good agreement with the literature, but the TexNIRS enables a much higher level of comfort.
