Active clinical trials for "Hypoxia"

Severe H1N1 pneumonia with acute respiratory failure shows hyperactive immune cells infiltration of lung. Rapamune, a mTOR inhibitor, modulates the immune response by blocking activation of T- and B-cells. To investigate the clinical efficiency of rapamune in severe H1N1 pneumonia with respiratory failure, this study was conducted.

Globally, approximately 2.1 million children die of pneumonia each year. Most deaths occur in resource-poor settings in Africa and Asia. Oxygen (O2) therapy is essential to support life in these patients. Large gaps remain in the case management of children presenting to African hospitals with respiratory distress, including essential supportive therapies such as supplemental oxygen. We hypothesize that a novel strategy for oxygen delivery, solar-powered oxygen, can be implemented in remote locations and will be non-inferior to standard oxygen delivery by compressed gas cylinders.

The purpose of the study is to combine and correlate data from morphological and functional MRI, molecular signatures of tumor hypoxia, the presence of micrometastases and tumor hypoxia with the goal being predicting of prostate cancer aggressiveness.

The purpose of this study is to determine whether the plasticity of autologous intrathecal hematopoietic cells would improve the neurologic evolution of the pediatric patients with hypoxic/ischemic brain injury.

This is a research study of head cooling. Its goal is to determine whether cooling babies' heads can reduce or prevent brain damage that may have resulted from temporarily reduced oxygen supply to the brain. In this study, half of the babies (selected at random) will have a special cooling cap with circulating water placed on their head for 72 hours to lower the temperature of their brain. The rest of the baby's body will be maintained at a defined temperature by a standard overhead radiant heater. The study protocol includes the taking and analysis of blood samples, performance of brain wave tests, imaging of the brain by ultrasound, and other tests as clinically indicated. Neurodevelopmental outcome will also be assessed at 18 months of age.

This study examines the potential benefits of a home stimulation program to treat infants who have suffered from brain asphyxiation (lack of oxygen). The program involves one year of stimulatory activities. Progress will be evaluated through neurological and behavioral exams.

Several projects in high altitude research in environments with a low oxygen partial pressure (hypobaric hypoxia) leading to hypoxemia showed, that cerebral perfusion and cerebral performance could be improved by adding C02 (cabon dioxide). The investigators hypothesize that adding 5% C02 to 02 (Oxygen) also under normobaric conditions increases the time until a significant cerebral hyopxia is measured by near infrared spectroscopy (NIRS) compared to the administration of 95% 02. lf this hypothesis proves to be true, this approach might be used in situations in which individuals are prone to cerebral hypoxia. In bariatric surgery, patients that experience an apnea phase are more prone to (cerebral) hypoxia due to the fact, that they have a higher body mass index (BMI) leading to a reduced functional residual capacity (FRC), which serves as the oxygen reserve in the body.

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.

The aim of the study is to determine the physiological evidence of how muscular and cerebral oxygenation changes link to fatigue, physical, and cognitive performance after moderate-intensity exercise in sedentary older adults with type 2 diabetes.

The risk of respiratory failure after cardiac surgery is high, and it may result in many complications. The maneuver of alveolar recruitment may improve the oxygen transport in the human organism. The investigators compare three different types of alveolar recruitment in patient after cardiac surgery, to reveal which one is better.
