“…21 The unknown variability of the arterial to venous blood volume ratio in the interrogated tissue is a source of error for cerebral oximetry, 21 as is the use of an assumed O 2 consumption to calculate cardiac output. 39 Finally, analyses of differences between groups in oxygen deltas (e.g., ΔSaO 2 –ScO 2 , ΔSaO 2 −REF CX, and ΔSaO 2 –SjbO 2 ) were not adjusted for baseline variables. We would expect the findings of this study to be similar with other NIRS devices.…”

“…These data (total system volume and rate of N 2 O disappearance) are used for calculating the total PBF that participates in gas exchange. This system was developed for spontaneously breathing patients and has been extensively validated in various types of spontaneously breathing patient populations including patients with heart failure [37,38], PH [39,40], atrial fibrillation [41,42], and pulmonary disease [43,44], as well as in pediatric patients [45]. Overall, IGR demonstrated good agreement with gold standard methods including PAC thermodilution, the Fick method, and cardiac magnetic resonance-derived CO in these patient populations.…”

“…Renal perfusion is strictly prescribed by cardiac output . Methods to measure cardiac output include cardiac catherization and MRI, but the former is invasive, whereas the latter is time‐consuming and technically demanding . Echocardiography is the standard and convenient diagnostic modality for cardiomyopathy in DMD patients but may be hampered by scoliosis and poor echocardiographic acoustic windows, particularly in advanced stages .…”
