Background: Oxygen therapy is a cornerstone treatment of critically ill patients in the intensive care unit (ICU). Whether lower oxygenation therapy brings superior survival outcomes to higher oxygenation therapy is unknown.
Methods: We will search electronic databases: PubMed, Embase, Web of Science, the Cochrane Central Register of Controlled Trials (CENTRAL), International Clinical Trials Registry Platform (ICTRP), and ClinicalTrials.gov from inception to 1 January 2024. Two authors will independently screen for all eligible clinical studies. Emails will be sent for individual participant data. The statistical analyses will be conducted using STATA 15.0 software.
Results: We will evaluate the efficacy of lower oxygenation therapy compared with higher oxygenation therapy based on individual participant data.
Conclusion: This study will offer clinical evidence for oxygen therapy in ICU patients.

Introduction: Preclinical studies have shown that oxygen therapy can improve ischaemic brain tissue oxygen tension, reduce reperfusion injury after revascularisation, promote neuroregeneration and inhibit inflammatory responses potentially exerting a beneficial effect after endovascular treatment (EVT) in patients with acute ischaemic stroke (AIS). However, the optimal fraction of inspired oxygen (FiO) during EVT under general anaesthesia is currently unknown. Therefore, we are conducting a randomised controlled trial (RCT) to evaluate the impact of high-concentration oxygen vs low-concentration normobaric oxygen on early neurological function after EVT.

Study Objective: To assess whether, in a lung resection cohort with a low probability of confounding by indication, higher FiO is associated with an increased risk of impaired postoperative oxygenation - a clinical manifestation of lung injury/dysfunction.
Design: Pre-specified registry-based retrospective cohort study.
Setting: Two large academic hospitals in the United States.

The tumor microenvironment characterized by heterogeneously organized vasculatures causes intra-tumoral heterogeneity of oxygen partial pressure at the cellular level, which cannot be measured by current imaging techniques. The intra-tumoral cellular heterogeneity may lead to a reduction of therapeutic effects of radiation. The purpose of this study was to investigate the effects of the heterogeneity on biological effectiveness of H-, He-, C-, O-, and Ne-ion beams for different oxygenation levels, prescribed dose levels, and cell types.

Background: In recent times, the applications of continuous renal replacement therapy (CRRT) beyond kidney-related conditions have been progressively increasing, and its implementation in randomized controlled trials (RCTs) specifically for acute respiratory distress syndrome (ARDS) has been documented. This meta-analysis compiles all existing RCTs to assess whether CRRT benefits ARDS.
Methods: We searched 12 databases in English and Chinese and two clinical trial centers up to November 28, 2023.

People with peripheral arterial disease (PAD) and intermittent claudication (IC) experience impaired walking due to an imbalance between muscle oxygen supply and demand during exercise. Studies with near-infrared spectroscopy (NIRS) during treadmill tests reveal notable tissue deoxygenation with slow recovery. This cross-sectional study aimed to compare behavior of calf muscle oxygenation during the incremental shuttle walking test (ISWT) with a continuous treadmill test (3.
