Capnodynamics – noninvasive cardiac output and mixed venous oxygen saturation monitoring in children [PDF]

Frontiers in Pediatrics, 2023
Hemodynamic monitoring in children is challenging for many reasons. Technical limitations in combination with insufficient validation against reference methods, makes reliable monitoring systems difficult to establish.

Correlation between central venous oxygen saturation and mixed venous oxygen saturation in surgical patients: A systematic review and meta-analysis [PDF]

Annals of Intensive Care
Background: The validity of central venous oxygen saturation (ScvO2) as a surrogate for mixed venous oxygen saturation (SvO₂) in surgical patients remains uncertain. Methods: We systematically searched PubMed, Embase, the Cochrane Library, China National

Association between mixed venous oxygen saturation and serum uric acid levels in patients with heart failure. [PDF]

PLoS ONE
Hypoxia leads to increased purine metabolism in tissues, resulting in increased serum uric acid levels, and may also cause impaired uric acid excretion in the kidneys and intestinal tract.

Validation of the capnodynamic method to calculate mixed venous oxygen saturation in postoperative cardiac patients [PDF]

Intensive Care Medicine Experimental
Background Cardiac output and mixed venous oxygen saturation are key variables in monitoring adequate oxygen delivery and have typically been measured using pulmonary artery catheterisation. The capnodynamic method measures effective pulmonary blood flow

Noninvasive tracking of mixed venous oxygen saturation via near-infrared spectroscopy cerebral oximetry: a retrospective observational study [PDF]

Scientific Reports, 2023
Although previous studies have shown correlation between regional cerebral oxygen saturation (rScO2) and mixed venous oxygen saturation (SvO2), there is a lack of pragmatic information on the clinical applicability of these findings, such as tracking ...

Changes in Arterial–Alveolar Oxygen Gradient and Mixed Venous Oxygen Saturations in Mechanical Thrombectomy for Pulmonary Embolism: A Prospective Cohort Study [PDF]

Pulmonary Circulation
Large bore mechanical thrombectomy (LBMT) is an effective therapy for intermediate‐high risk PE, however, objective physiological endpoints to guide intraprocedural decision‐making remain poorly defined. The alveolar–arterial (A–a) oxygen gradient, mixed

pFOE or pFTOE as an Early Marker for Impaired Peripheral Microcirculation in Neonates

Children, 2022
Background: Peripheral-muscle-fractional-oxygen-extraction (pFOE) and peripheral-muscle-fractional-tissue-oxygen-extraction (pFTOE) are often equated, since both parameters are measured with near-infrared-spectroscopy (NIRS) and estimate oxygen ...
