HYPOXEMIA

This study tested whether giving heart failure patients with fluid in their lungs a lower oxygen target (90% oxygen saturation) or a higher one (96%) leads to better outcomes. 122 patients were randomly assigned to one of the two groups in the emergency department. The goal was t…

This study tested two oxygen delivery methods—a special mask and a high-flow nasal tube—in 30 children aged 6 to 16 during a stomach scope procedure. The goal was to see which method better prevents dangerously low oxygen levels. Results will help doctors choose the safest approa…

This study compared two sedatives, dexmedetomidine and propofol, in 100 high-risk patients undergoing ERCP. The goal was to see which drug causes fewer breathing and heart problems. Researchers monitored vital signs closely to find the safer option for these vulnerable patients.

This study tested whether a nasal mask or a standard nasal cannula is better at preventing low oxygen levels during gastrointestinal endoscopy. 600 adults were randomly assigned to receive oxygen through one of the two devices while sedated with propofol. The goal was to see whic…

This study tested whether giving a special high-flow oxygen through the nose during a sedated gut procedure (ERCP) could prevent dangerously low oxygen levels better than standard oxygen. One hundred adults and older patients took part. The goal was to see which method keeps oxyg…

This study tested whether a special oxygen mask that covers the mouth and nose works better than a standard nasal cannula to prevent low oxygen levels during ERCP, a scope procedure for the bile duct. Researchers enrolled 150 adults aged 18-75 and measured how often oxygen levels…

This study tested whether a special oxygen mask (POM) works better than a standard nasal cannula to prevent low oxygen levels in children aged 6-16 during an upper GI endoscopy. 114 children took part. The goal was to see which method keeps oxygen levels more stable and reduces b…

This study tested whether a high-flow nasal cannula (HFNC) can reduce the risk of low oxygen levels during sedated gastrointestinal endoscopy in 80 adults with high-risk obstructive sleep apnea. Participants had a STOP-Bang score of 5 or higher and were undergoing gastroscopy, co…

This study compared two sedation methods for children aged 3 months to 10 years undergoing MRI: a combination of propofol and ketamine given through a vein, versus sevoflurane gas given through a face mask. The goal was to see which method allows faster recovery and fewer side ef…

This study looked at how short periods of low oxygen (from holding your breath) affect blood sugar levels after drinking a sugary drink. Researchers tested 20 healthy adults, people with prediabetes, and people with type 2 diabetes. The goal was to learn more about how oxygen lev…

This study looked at 165 trauma patients to see how often they had low blood oxygen (hypoxemia) during their first 24 hours in the hospital. Researchers used a special finger clip to track oxygen levels and compared daytime vs. nighttime episodes. The goal was to understand when …

This completed study looked at 1,000 patients who had heart surgery and were then moved to the ICU. Researchers tracked whether high or low oxygen levels increased the chance of developing delirium, a state of confusion. The goal was to understand how oxygen management might affe…

This study tested whether giving 50% or 100% oxygen before removing a breathing tube after anesthesia leads to fewer drops in oxygen levels. 119 patients were monitored after surgery. The goal is to find the safest oxygen setting to prevent breathing problems during recovery.

This study looked at 222 adults having a sedated gastroscopy to see if a high-flow oxygen device called THRIVE prevents low oxygen levels better than a standard nasal cannula. The oxygen method was chosen by the doctor, not randomly assigned. The main goal was to see how many pat…

This study tested three different oximeters (Masimo, Nellcor, Nonin) at various oxygen targets in 40 patients with and without COPD. The goal was to see how the choice of oximeter and target affects the amount of oxygen needed. Results could help guide safer oxygen therapy.

This study tested whether using a monitor that tracks breathing and oxygen levels (called IPI) can prevent dangerous oxygen drops during ERCP, a procedure to examine the bile ducts. 80 adults having elective ERCP under moderate sedation were randomly assigned to either standard m…

This study checked how accurately a simple finger clip (pulse oximeter) measures oxygen levels compared to a blood test in 152 ICU patients getting extra oxygen. Researchers wanted to see if the non-invasive device matches the more precise blood gas analysis. The results could he…

This completed study looked at whether COVID-19 patients treated with steroids might have a reactivation of hepatitis B virus (HBV). Researchers followed 1,793 hospitalized adults who needed oxygen and received steroids for COVID-19 pneumonia. The goal was to see how well doctors…
