Filter by:Twelve male wrestlers of the National Polish Team were observed in the study during the camp. The hypoxia group (n=6) participated in sports training and hypoxic exposure, while the control group (n=6) included wrestlers participating only in sports training. The hypoxic group lived and slept in hypoxic rooms. During the camp, all wrestlers followed the same training schedule and diet. In the blood were determined levels of creatine kinase (CK), C-reactive protein (hsCRP) concentration, nitric oxide (NO), morphology, reticulocytes, lipid profile, and ferritin. Also vascular endothelial growth factor (VEGF, VEGFR2, and VEGFR3), erythropoietin (EPO), angiopoietin (Ang 1, Ang 2), endothelial cell adhesion factor-1 (VCAM-1), Erythropoietin (EPO) and hypoxia-inducible factor 1 (HIF-1). Body weight composition was determined.
The main aim of this randomized controlled trial is to evaluate cerebral blood oxygenation after 7-day administration of a creatine-guanidinoacetic acid (GAA) mixture in healthy adults before, during, and after a series of cognitive tests.
The goal of this clinical trial is to evaluate the effects of minimal enteral nutrition (MEN) on mesenteric blood flow and oxygenation with Doppler USG and Near Infrared Spectroscopy (NIRS) during therapeutic hypo¬thermia (TH) in babies with hypoxic ischemic encephalopathy. The main question it aims to answer is: 1- How do the mesenteric blood flow and oxygenation get affected with MEN during TH? Participants will be either fed with MEN during TH or given placebo.
Severe traumatic brain injury with a decrease in cerebral oximetry is associated with multiple impaired systemic microcirculations, more morbidities, and a higher mortality rate. When using the brain as an index organ, interventions to improve brain oxygen delivery may have systemic benefits for these patients.
The response to hypoxia is very individual and epending on many aspects, such as the type of training, duration, intensity, or hypoxic stimulus, hypoxia affects the athlete in various ways. The results of this study have shown that 18 days of the LH-TL method does not significantly increase the level of EPO and VEGF in rowers. However, reticulocytes, immature red blood cells, have shown significant differences after 18-d LH-TL between groups. Further research should be carried out to investigate an optimal hypoxic dose and time, which will raise EPO, VEGF, and morphology variables.
The purpose of this clinical study is to validate the SpO2 accuracy of the Stryker Sustainability Solutions pulse oximetry sensors during motion conditions over the range of 70 -100% SaO2 as compared to arterial blood samples assessed by CO-Oximetry during conditions in which the subject is moving. The end goal is to provide supporting documentation for the SpO2 accuracy validation of the reprocessed sensors with motion indications.
The goal of this study was to evaluate the accuracy of pulse oximeters over the range of 70-100% per ISO 80601-2-61:2019. Four devices were placed on each subject with two on each index finger at the base and two on each index finger at the fingertip. SpO2 measurements from these devices were compared to sampling of arterial blood during brief stable oxygen desaturation in healthy volunteers to evaluate the claimed range.
This study specifically aims to elucidate the effects of IEK on sleep and recuperation in hypoxia, after training in normoxia. These conditions are in line with the widely applied live-high train-low strategy. Moreover, blood and tissue oxygenation status, as well as cerebral blood flow and cognitive function will be assessed.
To study the effect of high flow nasal cannula in comparisons with nasoprong used intraoperatively in patients oxygenation status
The incidence of hypoxemia during gastrointestinal endoscopy sedation is high, but there is still a lack of perfect prediction model of hypoxemia, which often leads to unpredictable respiratory complications. In order to ensure the safety of gastrointestinal endoscopy sedation and make emergency plans in advance, a better diagnostic model is urgently needed to help assess the risk of hypoxemia in patients undergoing the process and make early intervention measures. Facial photography is a simple and feasible measure that can show the facial soft tissue and structure of bone. The purpose of this study is to explore whether facial photography combined with other clinical indicators can build a prediction model of hypoxemia during gastrointestinal endoscopy sedation.
