Randomized crossover trial in patients with pulmonary arterial hypertension (PAH) and chronic thromboembolic pulmonary Hypertension (CTEPH) to assess the acute response to simulated altitude (FiO2:15.1, equivalent to 2500m above sea level) on blood and tissue oxygenation (ABGA, near infrared spectroscopy)
Randomized crossover trial in patients with Pulmonary Hypertension (PAH, CTEPH) to assess the acute response to simulated altitude (FiO2:15.1, equivalent to 2500m above sea level) on pulmonary artery pressure and right heart function (Echo).
To determine the safety of single and repeated intravenous doses of hCT-MSC in newborn infants with HIE.
Pulse oximetry monitoring is considered a standard physiological measurement and is used by clinicians in everyday situations to estimate arterial oxygen saturation. There are two devices used in this investigational study: BabySat v.1.0 and Owlet Baby Care, Inc. Smart SockTM 2 (currently available over-the-counter), with specific emphasis on its pulse oximetry accuracy. The BabySat and Smart SockTM 2 are non-invasive home care devices for use with infants. The purpose of this study was to validate the SpO2 accuracy of BabySat v1.0 and Owlet Smart SockTM 2, OSS v1.1 sensors pulse oximetry, during non-motion conditions over the range of 70-100% SaO2 as compared to arterial blood samples assessed by CO-Oximetry.
This study evaluates the use and effects of supplementary oxygen in surgical and medical wards on patients admitted to a hospital in the capital region of Denmark. The population will be divided in to three groups according to their oxygenation status. The main outcome will be 30-day mortality, with secondary outcomes being Length of stay, 30-day admission to ICU, 30-day reoperations, 30-day readmission, and peak values within 30-days of C-reactive protein, S-Creatinine, Troponin.
Present study suggests that excessive occlusal forces did not cause a significant change in hypoxia and vascular markers, however a slight alteration in subgingival microbiota was observed.
The purpose of the present study is to determine whether there are sex differences in the reflex responses to hypoxia in humans.
Intubation of patients in the intensive care unit (ICU) carries a risk of potentially severe complications, including cardiac arrest. Hypoxemia is common in ICU patients requiring intubation, which must be performed rapidly to avoid aspiration, since the patient is usually not in the fasted state. Studies have assessed interventions designed to improve intubation success rates, such as routine neuromuscular blockade. Care bundles combined with training on simulators have improved the safety of intubation. Nevertheless, intubation in the ICU still carries higher morbidity and mortality rates compared to intubation in the operating room. Preoxygenation is a cornerstone of safety for intubation in the ICU. Several recent trials have investigated different devices (non-rebreather mask, non-invasive ventilation, high flow nasal cannula, bag valve mask) with conflicting results. A main reason for those results is that efficiency of the preoxygenation period cannot be evaluated in the ICU in opposite to the operating room: gas monitoring are not available in ICU and even if it was the case, high flow demand from the patient, and agitation will make it inefficient. Additionally, desaturation is frequent (from 10% up to 50%) during intubation in ICU and lead to morbidity and mortality; so anticipation of desaturation is a major concern for ICU's physician because it's impacting care (face mask ventilation, early insertion of subglottic device). The oxygen reserve index (ORI) is a new parameter for monitoring oxygen reserve non-invasively. In this context, the investigators purpose to analyze efficiency of preoxygenation and time allowed by ORI for medical interventions before hypoxemia during intubation in the ICU in a pilot observational study in our medical ICU in a university hospital.
