Filter by:The main aim of this randomized controlled trial is to evaluate cerebral blood oxygenation after 7-day administration of a creatine-guanidinoacetic acid (GAA) mixture in healthy adults before, during, and after a series of cognitive tests.
The goal of this observational study is to investigate the occurrence of hypoxemia (an abnormally low concentration of oxygen in the blood) in trauma patients within the first 24 hours of hospital admission following arrival to a trauma center. The main questions the study aims to answer are: - Do trauma patients experience hypoxemia during the initial 24 hours of hospital admission following trauma? - What is the daily distribution of potential hypoxemic episodes? The investigators expect that hypoxemic episodes will be more frequent during the night (20.00-07.59) than during the day (08.00-19.59) An additional pulse oximeter will be attached to the participants, which measures oxygen saturation in the blood during the first 24 hours of hospital admission after trauma.
The purpose of this study is to assess patients with chronic heart failure and moderate-severe ventricular dysfunction (left ventricular ejection fraction (FEVE) <40%) with nocturnal desaturation (mean Oxygen saturation (SatO2) <90% and/or Cummulative time (TC) <90% > 22 minutes) without underlying respiratory disease, oxygen treatment during hours of night rest will reduce exacerbations, improve the ability to effort, sleep quality and poor prognostic parameters of heart failure, compared to patients not receiving oxygen treatment.
The objective of our study is to evaluate the effectiveness of prone position in preventing intubation or death in spontaneously ventilated patients with COVID-19 with acute respiratory failure.
Pulmonary rehabilitation (PR) is a validated treatment in patients with Chronic Obstructive Pulmonary Disease (COPD), improving exercise tolerance, quality of life and dyspnea. However, 20 to 30% of patients did not respond to PR and particularly those with chronic hypoxaemia. In most disabled patients, High Intensity Interval training (HIIT) is an alternative to perform exercise training with similar gain in exercise capacity than continuous exercise training. In patients with exercise-induced oxygen desaturation, the repetitions of hypoxia/resaturation phases during intermittent exercise could result in bursts of oxidative stress and induce positive or detrimental effect on mitochondrial function according to the importance in the oxidant stimulus. Few data have ascertained the benefit of HIIT on mitochondrial oxidative capacity (Vmax) in healthy subjects compared to continuous exercise training but no data are available in COPD patients with exercise-induced desaturation, and the change in oxidative stress in such training regimen. The investigators hypothesize that the repetitive bursts of oxidative stress and the improved antioxidant capacity in the course of the training sessions would stimulate mitochondrial adaptations to a larger extent after HIIT than continuous exercise training in severe COPD patients with hypoxemia. Moreover, they will assess the relationship between the change in oxidative stress in blood and in muscle. The clinical relevance of this study will be to ascertain the benefit and the safety of HITT in this subgroup of COPD patients in whom benefit of PR is often weak.
The type of this study is an observational prospective study. It will be done to determine the oxygenation status of the intercostal muscles and quadriceps femoris muscle during exercise in patients with fibrosing lung and to examine its relationship with exercise capacity, respiratory functions and respiratory muscle strength. The main questions that the study aims to answer are: - Question 1: Do changes in muscle oxygenation during exercise affect respiratory functions in patients with Fibrosing Lung? - Question 2: Do changes in muscle oxygenation during exercise affect exercise capacity in patients with Fibrosing Lung? Participants; demographic information such as age, height, weight will be questioned. Respiratory functions will be evaluated with a desktop spirometer, peripheral muscle strength measurement will be evaluated with a digital myometer, and functional capacity will be evaluated with a 6-minute walk test (6MWT). The Moxy device, which is a non-invasive near-infrared spectroscopy (NIRS), will be attached to the upper leg (the vastus lateralis of the quadriceps muscle) and the rib (intercostal muscles) with a silk patch, and the oxygenation of the muscles here will be measured during the 6-minute walking test. In addition, fatigue status will be evaluated with the Modified Borg Scale.
Anesthesia induction is associated with hemodynamic imbalances that can affect the blood flow to major organs. Moreover it can result in deoxygenation as well. During standard anesthesia induction the patient is manually ventilated with a circle-valve-mask system until the effect of muscle relaxant shows of. Near-infrared spectroscopy (NIRS) is a modification of a well-known peripheral pulse oxymetry that is used in the detection of the regional oxygen saturation (rSO2) in organs, including brain, liver, muscle, and intestines. In this study we will compare the regional oxygenation status of the patients during anesthesia induction in which either standard manual ventilation or mechanical ventilator-assisted ventilation was performed. AutoFlow(R) mode of Draeger-Perseus mechanical ventilator will be used for the ventilator-assisted ventilation.
Sedoanalgesia is applied to patients during gastrointestinal endoscopy. Sedoanalgesia may cause respiratory depression and hypoxia in patients. During these procedures, patients should be given oxygen support to reduce the incidence of hypoxia.This study aimed to compare the efficacy and procedural performance of two different airway devices (Wei Nasal Jet Tube vs Nasal Cannula Oxygen Support) in Gastrointestinal Endoscopy
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.
The current methods of oxygen supply administer medicinal oxygen to the patient at a constant flow. Oxygen is being delivered when the patient needs it (at inhalation) and when the patient does not need it (at exhalation and at rest) if the volume of oxygen needs to be adjusted, the clinician typically increases the rate of flow in an effort to increase the oxygen concentration in the air inhaled by the patient. This traditional way of administering oxygen is clinically effective but it also wastes significant amounts of oxygen that the patient never uses. The BUFEO system addresses this problem by altering the supply of oxygen to an on-demand delivery model, the patient receives oxygen only when needed (during inhalation) and no oxygen is wasted at rest or during exhalation. The aim of this study is to evaluate, the efficacy, tolerability, and non-inferiority in SpO2 of the BUFEO device in saving oxygen and reaching a target SpO2 rate, in comparison to the standard of care by measuring the volume of oxygen used and the SpO2 reached when administering medical oxygen with the traditional supply method and through BUFEO system to hospitalized, oxygen-dependent subjects with pulmonary pathology.
