Active clinical trials for "Hypoxia"

A feasibility study to inform the design and conduct of a randomised controlled trial of high flow nasal cannula (HFNC) versus continuous positive airway pressure (CPAP) for non-invasive respiratory support in critically ill children

The goal of this proposal is to profile the pharmacokinetics of dexmedetomidine in newborns ≥36 weeks post-menstrual age during therapeutic hypothermia for hypoxic-ischemic encephalopathy.

This study is designed to determine if using peripheral nerve stimulation in conjunction with pulse oximetry as an adjunct to traditional monitoring in the PACU reduces the frequency and severity of sedation related apnea and hypoxic events.

Accumulating evidence suggests that repeatedly breathing low oxygen levels for brief periods (termed intermittent hypoxia) is a safe and effective treatment strategy to promote meaningful functional recovery in persons with chronic spinal cord injury (SCI). The goal of the study is to understand how caffeine may augment the effects of intermittent hypoxia on motor function and spinal plasticity (ability of the nervous system to strengthen neural pathways based on new experiences) following SCI.

Hypoxia/bradycardia are common symptoms after vaccination of preterm infants. Adults show diurnal variations in vaccination response, due to circadian regulation of the immune system. The investigators plan to investigate whether preterm infants also show differences in hypoxia/bradycardia rate upon morning vs. evening vaccination. Hypoxia/bradycardia is recorded by pulse oximetry starting 24 hours before until 48 hours after vaccination; parents also kept a sleep-diary. 24 hours after vaccination interleukin-6, interleukin-1β and C-reactive protein get determined. To control vaccination response, pertussis- and haemophilus-titers are determined before vaccination and at 4 months corrected age.

Oxygen is a widely available gas that is cheap, easy to get and extensively used in medicine. From animal studies it has become apparent that increasing or lowering the degree of oxygen in the blood, the inflammatory response can be altered. We will investigate of this is also true in humans by increasing, lowering or keeping oxygen levels normal while giving healthy subjects a short inflammatory stimulus.

This pilot phase II trial studies how well EF5 works in measuring lack of tumor oxygen, hypoxia, in patients with stage I-III non-small cell lung cancer. EF5 may be effective in measuring the lack of oxygen in lung tumors and may allow doctors to plan better treatment.

During early postoperative after lung resection surgery, patients without oxygen supplementation may experience hypoxemia. Oxygen supplementation can be given via oxygen mask or cannular. In this study the investigators want to the sudy the effect of oxygen supplementation via oxygen cannular during the first 120 minutes after surgery

Current treatments for ARAS based on restoring blood flow alone have been unsuccessful at recovering kidney function. For this reason we are studying a stem cell product called "mesenchymal stem cells" or MSC. Mesenchymal stem cells (MSC) are grown from a person's own fat tissue (obtained as a fat biopsy) and infused back into the patient's own kidney. This study is also being done to determine if the MSC infusion prior to percutaneous transluminal renal angioplasty with stenting (PTRA) further enhances changes in single kidney blood flow and restoration of kidney function, as well as to assess the relationship between MSC dose and measures of kidney function.

The purpose of this study is to investigate the effectiveness and safety of selective head cooling (SHC) in neonatal hypoxic-ischemic encephalopathy (HIE).
