Comment 1. These values are from NIR measurements using IQ system (mean ± standard error, n = 9). Comment 2. These are calculated from SvO2 and StO2 which gives arterial venous blood volume ratio of 28.3%/71.7%. Comment 3. The blood flow is calculated from Eqs. 4–5. Comment 4. SaO2 is assumed 100%. Comment 5. SvO2 is assumed 49.1% ([24]). |
