Filter by:This study aims to determine whether the use of SOJV could reduce the rate of hypoxia during gastrointestinal endoscopic procedures in deeply sedated patients sedated at high altitude comparing to the supplemental oxygen administration via nasal cannula.
The aim of this randomized, double-blind study is to determine whether erythropoietin (Procrit) and acetazolamide: 1) mitigates altitude-induced decrements in performance at moderate altitude (3,000 m) and 2) mitigates altitude-induced decrements in performance and reduce acute mountain sickness during prolonged exposure to high altitude (4,300 m; 15 days). Volunteers will complete 5 study phases: Phase 1) sea level baseline testing and a moderate altitude exposure; Phase 2) 4 week study intervention - randomly assigned to receive erythropoietin or placebo); Phase 3) 3 1/2 days of acetazolamide and a moderate altitude exposure; Phase 4) high altitude acclimatization - 15 days at Pikes Peak; and Phase 5) two week deacclimatization. Test battery include VO2peak, 3.2 km treadmill time trial, measures of gas exchange and ventilation during rest and exercise, and blood collection.
The aim of this proposal is to characterize the acute effect of early postnatal sound exposure on neuronal maturation of the respiratory control regions of the brain in preterm infants.
Patients undergoing sedated bronchoscopy were randomized into six groups (10 Liters/minute [L/min], 20 L/min, 30 L/min, 40 L/min, 50 L/min, 60 L/min). The primary outcome was the incidence of hypoxemia.
The aim of this study is to determine the accuracy of devices called pulse oximeters, which measure blood oxygen by shining light through fingers, ears or other skin, without requiring blood sampling. Study will be used with patients at rest
A phase 1 study investigating the tolerability and pharmacokinetics of caffeine citrate in neonates with hypoxic ischemic encephalopathy receiving therapeutic hypothermia. This study is an essential first step to develop caffeine as a kidney protective medication in this in this vulnerable group of newborns.
Automated quantification of the pulmonary volume impaired during acute respiratory failure could be helpful to assess patient severity during COVID-19 infection or perioperative medicine, for example. This study aims at assessing the correlation between the amount of radiologic pulmonary alteration and the clinical severity in two clinical situation : 1. SARS-CoV-2 infections 2. Postoperative hypoxemic acute respiratory failure.
The purpose of this study is to better understand how hypoxia (low oxygen) affects resting and exertional right ventricular function in healthy individuals.
The purpose of this clinical study is to validate the SpO2 accuracy of the Stryker Sustainability Solutions pulse oximetry sensors during motion conditions over the range of 70-100% SaO2 as compared to arterial blood samples assessed by CO-Oximetry. The end goal is to provide supporting documentation for the SpO2 accuracy validation of the reprocessed sensors.
The purpose of this project is to identify sex-related differences in the effect of hypoxia on sympathetic vascular transduction.
