Table 2.
Tabulated absolute quantities from neck (channel 1) and ham (channel 2) of the diffuse optical spectroscopy instrument at baseline are shown. Recovered “A” and “B” parameters from the scattering power law in equation (1) are also provided. The baseline for each subject was defined as a 6 minute average prior to the start of hemorrhage.
| Parameter | Neck | Ham |
|---|---|---|
| HbO2 (µM) | 6.7±1.8 | 7.8±2.4 |
| HbR (µM) | 10.1±0.9 | 11.2±0.8 |
| StO2 (%) | 36.3±5.8 | 35.7±7.0 |
| THC (µM) | 16.6±1.6 | 18.7±2.3 |
| H2O (%) | 50.0±1.2 | 51.3±3.7 |
| FAT (%) | 32.7±2.7 | 45.2±2.8 |
| Scattering Parameter A | 2.1±0.1 | 2.1±0.3 |
| Scattering Parameter B | −1.6±0.1 | −1.6±0.2 |
Errors are reported as standard error.
(Note: HbO2 = Oxyhemoglobin; HbR = Deoxyhemoglobin; StO2 = Hemoglobin oxygenation saturation; THC = Total hemoglobin; H2O = Water; FAT = Lipid)
