Active clinical trials for "Hypoxia"

The study aims the assessment of endothelial glycocalyx (EG) degradation in deceased organ donors. There is a lack of organs for the transplantation program. By the description of the EG status, we can open room for organ optimization before transplantation and improve the organ function after transplantation in marginal donors.

With the oxygen mask with reservoir, oxygen can be given to patients with FiO2 values that can reach 80-100%. Reservoir oxygen mask is superior to other oxygen treatment methods with the high oxygen rate applied.Our hypothesis is that the use of an oxygen mask with a reservoir will reduce the incidence of respiratory complications in adult patients who will undergo sedation in the endoscopy unit.

Dyspnea is a common diagnostic challenge in the Emergency Department (ED). Delay in diagnosis will increase time to correct treatment and could impact outcome. Previous studies have shown excellent diagnostic performance of point of care ultrasound (POCUS) to detect and differentiate between several important diagnosis (e.g heart failure and pneumonia) in patients with dyspnea. However, in most studies POCUS is performed by physicians highly experienced in ultrasound and often studies have focused only on one or few diagnoses. The aim of this study is to compare the diagnostic accuracy of different diagnosis in dyspnoeic patients before and after a ED physician with limited training applies POCUS.

The purpose of this research study is to gather more information on how eye injury is related to a baby's future development and see if eye function and brain test results can be used, along with current measures, to better diagnose and treat babies with hypoxic-ischemic encephalopathy (HIE). Participants will undergo up to two eye exam sessions, involving both Visual Evoked Potential (VEP) and Electroretinogram (ERG) exams.

DDA is a new Doppler parameter aiming to assess fetal well-being in-utero. Late-onset FGR is a specific subgroup of fetuses where the clinical application of this Doppler modality could play an essential role in detecting hypoxia, anemia, and other adverse neonatal outcomes.

Establish a pulmonary hypertension registry and biorepository to lead towards a further understanding of the disease.

Patients with locally advanced cervical cancer (LACC) are primarily treated with radiotherapy +/- chemotherapy however 5-year survival rates are <60% with significant treatment toxicity. Hypoxia is a well-known radioresistant component of solid tumours such as cervical cancer and hypoxia modification therapies have demonstrated immense promise in treating such tumours. A major factor in determining a successful outcome with hypoxia modification is appropriate patient selection as it is hypoxic tumours that receive the most benefit from hypoxia modifying therapies. To date there is no validated hypoxia biomarker to stratify patients for therapy in cervical cancer in clinical use. This project offers a unique opportunity to examine both genetic and imaging biomarkers to optimise patient stratification when receiving curative radiotherapy for cervical cancer.

Pediatric idiopathic pulmonary hypertension has significant morbidity and mortality. An ever expanding body of knowledge indicates the important contribution of inflammation to pathogenesis and successful treatment with glucocorticoids. Over the last several years the investigators have utilized steroids in patients with severe pulmonary hypertension as part of a treatment regimen. These basic science studies possibly identifies a biochemical etiology for the development of disease and may also be impacted by the administration of steroids. Additionally, there is a commercially available assay which tests for all of the above molecules.

Pneumonia is a lung infection. Fiberoptic bronchoscopy is a test to diagnose the type of lung infection. While this procedure is being performed, a small amount of oxygen is delivered into the nose (low flow nasal cannula). Occasionally during this procedure, the blood oxygen of the patient may drop and an intervention such as increasing the oxygen flow, or placing the patient on a breathing machine is required. An alternative device called 'Optiflow' can provide high flow oxygen through nasal cannula, and is comfortable for patients. If Optiflow is used during bronchoscopy, it may prevent the blood oxygen from dropping.

Due to the hypobaric hypoxia during air travel, some patients with Cystic Fibrosis (CF) need supplemental oxygen during air travel. The study aims to evaluate if adding exercise desaturation to the pre-flight evaluation will help predict requirements for in-flight supplemental oxygen.
