ASpirin as a treatment for ARDS (STAR): a phase 2 randomised controlled trial
… requirement. The primary endpoint was oxygenation index at day 7. Secondary outcomes included respiratory compliance (Crs), PaO2/FiO2 ratio, change in sequential organ failure assessment (SOFA) score and safety parameters. Analyses were by intention to treat. <br/><br/>Measurements and …

The non-invasive quantification of cutaneous haemoglobin and its oxygenation by reflectance spectrophotometry
… the amount of haemoglobin, the "haemoglobin index", and oxygen saturation, the "oxygenation index", in a blood containing sample. The haemoglobin index is derived from the spectrum of haemoglobin as the difference between two gradients calculated between three isobestic points (527.5,544, and …

Accurate noninvasive monitoring of fetal tissue oxygenation level
Fetal blood oxygenation level serves as a critical indicator of fetal health throughout pregnancy and labor. However, existing clinical devices predominantly employ invasive techniques, posing risks to both the fetus and the mother. To address this concern, we present a noninvasive method for …

The Role of Oral Nitrate Reducing Bacteria in Cardiovascular Health: Impacts of Diet and Exercise
… hyperaemia testing indicated enhanced tissue oxygenation index (TOI) post-exercise (peak TOI: 84.8% to 86.1%; P = 0.01) in the placebo condition, a response absent with mouthwash. Overall, exercise-induced improvements in rectus femoris oxygenation were significantly blunted by antibacterial …

Partielle Flüssigkeitsbeatmung im Vergleich zur konventionellen Beatmung und zur Hochfrequenzoszillation mit Surfactanttherapie : Auswirkungen auf Gasaustausch und Lungenpathologie im Neugeborenen-Tiermodell
… period. All groups showed an improvement of oxygenation index (OI) and PaO2/FiO2 ratio within the first 60 minutes after starting treatment. After 18 and 24 hours OI was significantly better in the PLV/CV group compared with the S + CV group. No differences in gas exchange were noted between …

Partielle Flüssigkeitsbeatmung im Vergleich zur konventionellen Beatmung : Auswirkungen auf Gasaustausch und Lungenpathologie im lungengesunden Neugeborenen-Tiermodell
… ventilated animals over 24 hours (CV). The oxygenation index (OI), PaO2/FiO2 ratio, Ventilationindex (VEI) and pH were determined by beginning and hourly during the 24h course. After 24 hours the lungs were removed for histopathological examination. Measurements and main results: The CV …

Partielle Flüssigkeitsbeatmung in Kombination mit Surfactanttherapie : Auswirkungen auf Gasaustausch und Lungenpathologie im Neugeborenen-Tiermodell
… substitution PLV with FC-77 was started. The oxygenation index (OI), PaO2/FiO2 ratio and PaCO2 were determined before and during PLV. After 24 h the lungs were removed for histopathological examination. Measurements and main results: Within 60 minutes after the initiation of PLV all animals …

Totale antioxidative Kapazität bei am Herzen operierten Kindern
… cardiopulmonary bypass (CPB). The role of the oxygenation with 100% O2 during CPB was investigated. The role of hypoxemia was investigated. The influence of ischemia-reperfusion injury and oxidative stress on clinical outcome was studied. 26 children (aged from 6 to 180 months) with cyanotic …

Effects of pulsed electromagnetic field therapy on symptoms associated with eccentric exercise-induced muscle damage
… reported to increase muscle blood flow and oxygenation to enhance tissue healing. One previous study showed that PEMFT was effective for alleviating muscle soreness and losses in range of motion after exercise. However, studies investigating the effect of PEMFT on recovery of muscle strength …

An investigation into regional ventilation in infants and children; its distribution and determinants
… in order to optimise ventilation and oxygenation. In acute respiratory distress syndrome (ARDS), prone positioning is reported to improve oxygenation by recruiting collapsed dorsal lung regions, although this has not been confirmed in children. Ventilation distribution is well …

The effects of melatonin on vascular function, oxidative stress and blood pressure reactivity during a high sodium diet
… (13M/11W, 27.0 ± 2.8 yrs., body mass index 23.8 ± 1.9 kg/m2, BP: 111/67 ± 8/7 mm Hg) participated in this study. There were no differences in 24-h mean arterial pressure (MAP) at the end of each intervention (HSD+PL: 83 ± 6 mm Hg; HSD+MEL: 82 ± 5 mm Hg; p=0.35). Melatonin …
