Filter by:The study aimed to evaluate different preoxygenation methods (tidal volume for 3 minutes and 4 deep breaths) in pregnant women with oxygen reserve index (ORI). After the routine monitoring of healthy ASA II pregnant patients between the ages of 18-45, different preoxygenation methods will be applied, and the oxygen status of the patients will be compared with ORI monitoring.
Coronary artery bypass grafting (CABG) with cardiopulmonary bypass is a common surgical therapy for patients suffering from coronary artery diseases. The heart is subjected to a long period of ischemia due to the occlusion of the aorta. The heavy burden of myocardial ischemia-reperfusion injury (IRI) thus induces cardiomyocyte death, which can paradoxically reduce the beneficial effect of CABG. Preconditioning by moderate hypoxia or hyperoxia serves as an effective drug-free method to increase the organism's resistance to negative effects, including IRI.
The aim of this study is to evaluate the impact of the FreeO2 system on the quality of the oxygen therapy in confirmed or suspected SARS-CoV-2 patients in the emergency department.
Supplemental oxygen is frequently administered in acutely and critically ill patients, specifically, it is often administered in trauma patients to avoid arterial hypoxemia and tissue hypoxia. There is also an increasing focus on potentially deleterious effects of hyperoxia. Further, the hemodynamic response to hyperoxia in hypovolemia is poorly understood. The present study aims to investigate the effects of supplemental oxygen on systemic and cerebral hemodynamics in simulated hypovolemia in healthy volunteers.
The purpose of this study is to evaluate the safety and efficiency of normobaric hyperoxia combined with endovascular treatment for acute ischemic stroke patients with stroke onset 6-24 hours.
The aim of the study was to assess the effect of intraoperative oxygen (O2), which was applied at 30% and 50% concentrations on patients who had undergone septoplasty surgery, on Total Oxidant Status (TOS), Total Antioxidant Status (TAS), and Oxidative Stress Index (OSI).
The overall incidence of good outcome for AIS following endovascular treatment is only proximately 50%. Whether NBO was safe and effective to improve acute ischemic stroke prognosis is still unclear. The investigators' hypothesis is thatNBO is a safe and effective strategy to improve longterm outcome in AIS patients undergoing endovascular treatment.
This is a multi-institutional study (CCF, UPMC, OSU) evaluating different ventilation strategies during cardiopulmonary bypass on mortality and postoperative pulmonary complications, with sub-study investigating 8-iso-prostaglandin F2a and sRAGE levels.
The aim of the study is to investigate a possible correlation between the change in PCO2 during a hyperoxia-test and the change in PCO2 during walking in people with COPD
The purpose of the study is to assess the optimal fraction of inspired oxygen (0.5 or 1) for extubation or removal of a supraglottic airway device after general anesthesia.
