  1. HSI Measurements are presented as mean with standard deviation as index (NIR, TWI, THI) or percentages with standard deviation (StO2). Difference was calculated between Measurement 1 and Healthy volunteers; CI confidence interval; NIR near infrared perfusion index; StO2 tissue oxygen saturation; TWI tissue water index; THI tissue hemoglobin index
