Evaluation of a low-cost portable NIRS device for monitoring muscle ischemia
Authors' conclusion
The study confirms the potential of HEGduino system to detect an interruption of the blood flow by means of variations in regional tissue oxygen saturation.
Study context
- Population
- Healthy participants aged 25–50 undergoing a vascular occlusion test on one forearm
- Participants
- 19 participants
- Outcome
- Evaluation of the low-cost, open-source HEGduino device as a tissue oximetry monitor (somatic NIRS monitoring)
Main finding
As reported in the abstract
- Difference between RED baseline values and normalized minimum always different from zero
- p < 0.014
- Difference between normalized IR baseline values and normalized minimum different from zero
- p < 0.001
- R-squared of noise variables on normalized RED values
- 0.08
- R-squared of noise variables on normalized IR values
- 0.105
