HYPOXEMIA

This study tests whether real-time carbon dioxide monitoring (capnography) can prevent dangerously low oxygen levels during painless gastrointestinal endoscopy. About 460 patients will be monitored with this device, which gives early warning of breathing problems. The goal is to …

This study looks at whether giving a common steroid (prednisolone) for 7 days can help hospitalized adults with severe lung infections and low oxygen levels. About 3,000 participants will be randomly assigned to receive the steroid or standard care without it. The goal is to see …

This study looks at whether portable oxygen therapy, adjusted to each person's needs, helps people with chronic lung diseases like ILD and COPD be more active and feel better in daily life. Twenty-four adults who only have low oxygen when walking or exercising will try two types …

This study looks at whether raising the head of the bed to 15 degrees (instead of lying flat) can reduce the chance of low oxygen levels during painless stomach and colon exams. About 400 adults will be randomly assigned to one of two positions. The goal is to find a simple way t…

This study tests whether a high-flow nasal cannula (a device that delivers warm, humidified oxygen) can prevent dangerously low oxygen levels in children aged 1 to 6 years during a sedated bronchoscopy (a procedure to look inside the lungs). About 430 children will be randomly as…

This study looks at whether measuring the windpipe with ultrasound before a lung biopsy can help predict if a patient will have low oxygen levels during the procedure. Researchers will measure the windpipe's width and compare it to the scope's size to see if a narrower windpipe r…

This study looks at whether a simple breathing measurement taken before weight-loss surgery can predict if a patient will have low oxygen levels in the first 12 hours after the operation. Researchers will follow 80 adults having bariatric surgery and check their oxygen levels and…

This study looks at whether frailty—a measure of overall health and weakness—can help predict dangerous drops in oxygen levels during a procedure called ERCP in people aged 65 and older. Researchers will first review past records of 313 patients, then test their predictions on 38…

This study will watch 100 adults after they have a sedated upper GI endoscopy to see how often their oxygen levels drop during recovery. Researchers want to learn how long these drops last and if they cause any problems. The goal is to better understand risks and improve care aft…

This study compares giving 30% oxygen versus the usual 100% oxygen before removing the breathing tube after abdominal surgery. The goal is to see if a lower oxygen level reduces the chance of low oxygen after extubation. About 590 adults having abdominal surgery will take part.

This study looks at whether a simple, non-invasive lung ultrasound can help doctors predict which patients will need extra oxygen or have lung complications after major surgery that is not on the chest. Researchers will follow 97 adults aged 18-65 who are having long surgeries (3…
