Long-term oxygen therapy improves survival in patients with severe hypoxia. However, some patients despite this oxygen, experience episodes of low oxygen levels (intermittent hypoxia) especially during sleep which may be harmful. In order to overcome this, the investigators have designed an auto-titrating oxygen system (called intelligent oxygen therapy) which automatically adjusts oxygen flow rates to maintain oxygen levels in patients already on oxygen. This study will invest...
Patients with lung disease experiencing difficulty breathing can be treated with oxygen therapy. This involves the delivery of "extra" oxygen by a face-mask or through small tubes placed in the nose called nasal prongs. This extra oxygen can have concentrations as high as 100% pure oxygen. The concentration of oxygen in normal air is only 21%. The high concentration of oxygen can help to provide enough oxygen for all of the organs in the body. Unfortunately, breathing 100%...
To evaluate changes in activity based on the use of portable oxygen concentrators combined with standard of care (SOC) long- term oxygen therapy versus SOC long-term oxygen therapy alone at 12 weeks in patients with COPD who require continuous (24/7) long-term oxygen therapy. The study will also assess oxygen usage, quality of life, hospitalizations and death.
This study will evaluate patient comfort and oxygen delivery efficiency when providing supplemental oxygen through a nasal cannula to volunteers using an instrumented oxygen delivery system. The goals of the study are to evaluate different oxygen flow rates and oxygen delivery modes. In addition, the investigators will investigate if the system can detect apnea (cessation of breathing) and removal of the nasal cannula. The investigators will also investigate how well high flow ...
The aim of this study is to investigate the effects of supplemental oxygen on blood oxygenation at rest in Patients with severe to very severe COPD comparing the portable oxygen concentrator (Activox™ 4L) to a liquid continuous oxygen device (Companion®).
The purpose of this study is to compare heat and humidified oxygen with cold and dry oxygen in children with bronchiolitis. The hypotheses are that heating and humidifying inspired low flow supplemental oxygen will optimize mucociliary function thereby, 1) improve oxygenation, 2) decrease work of breathing, and 3) decrease length of hospital stay.
The purpose of this study is to compare differences in oxygen delivery between portable oxygen concentrators (POCs) and liquid oxygen (LOs) portable units, pose a question if POCs are equally effective as LOs in reducing exercise-induced hypoxaemia. DESIGN: Randomized, single-blind clinical trial.
The purpose of this study is to evaluate if supplemental oxygen during air travel can be reliably titrated using a Hypoxia-altitude simulation test (HAST). Also, the effect of oxygen supplementation given with the various oxygen equipment allowed for air travel is studied.
The World Health Organisation recommends that all patients having a general anaesthetic for surgery should be given 80% oxygen as this might reduce their risk of getting an infection after their operation. However there remains a lot of uncertainty about how much oxygen patients should be given whilst undergoing surgery. In other areas of medicine evidence is slowly emerging to suggest that giving less oxygen may be as safe or even safer than giving high amounts of oxygen (e.g....
The main goal of this study is to determine if supplemental oxygen given only when the patient is inspiring (demand delivery) is more effective than constant-flow oxygen given during all phases of the breath regardless if the patient is breathing it in. A previous study in volunteers (NCT02886312) showed that the oxygen saturation in the blood and the concentration of oxygen breathed out from the lungs (end-tidal oxygen) was higher when given in demand (inhalation only) mode. A...
This study is a non invasive study to see if 100% oxygen therapy will help to resolve an intestinal obstruction.
The objective of this trial is to investigate whether treatment with oxygen in the early phases after a trauma plays a role in recovery.
This study evaluates effects of high inspiratory oxygen on cerebral tissue oxygenation and patient recovery after carotid endarterectomy. Two group of patient undergoing to carotid with total intravenous anaesthesia will receive either 35% inspired oxygen or 100% oxygen.
The effect of supplemental oxygen on surgical site infections was already investigated in several studies before. Although, oxygen is one of the most used medical therapy in hospitalized patients, the influence on the cardiovascular system is still unknown. Available data indicate beneficial effects of supplemental oxygen on cardiovascular function. Because, no evidence exists concerning the perioperative period, it is our objective to investigate supplemental oxygen in cardiac...
To compare the efficacy of long-term use of nocturnal oxygen therapy (12 hours) with that of continuous, low-flow oxygen therapy (24 hours) in patients with chronic hypoxic lung disease.
Oxygen is routinely given to patients with common conditions such as COPD and heart failure. There is no evidence behind giving oxygen to patients specifically in heart failure due to a stiff heart. This study aims to explore the effect oxygen has on the ability of patients with chronic heart failure and the ability to exercise. Other common variables will be assessed such as heart rate and blood pressure to observe the response to varying concentrations of oxygen. The ...
In this small pilot study, participants (patients and healthy volunteers) will have blood drawn before and after the study intervention (hyperbaric chamber session or normal pressure oxygen breathing. This blood will be analyzed for neutrophil oxidative burst and cytokine analysis.
Investigators hypothesized that a relative low SpO2 directed oxygen therapy would reduced the mortality in patients staying longer than 72 hours in ICUs.
Study Question: In infants who are born at gestational ages of 23 0/7 to 27 6/7 weeks, does lowering the concentration of supplemental oxygen to target an arterial oxygen saturation by pulse oximetry (SpO2)of 85-89% compared with 91-95%, from the day of birth until the baby's first discharge home, increase the probability of survival without severe neurosensory disability to a corrected age of 18 months?
The use of 100% oxygen during the induction of general anesthesia is always preferable in order to have enough time to secure the airway by endotracheal intubation, because preoxygenation with a low oxygen concentration may reduce the safe time for apnea. However, using a low oxygen concentration during preoxygenation might prevent the formation of atelectasis. There is still no clear conclusion about the best oxygen concentration for preoxygenation. Our study is designed to ev...
The study is designed to evaluate the feasibility, safety and clinical utility of using an adaptive model to wean oxygen by computer assistance. Investigators hypothesize that weaning oxygen using this model will decrease duration of exposure to hyperoxia, decrease duration of exposure to hypoxia, decrease exposure to increased oxygen requirement, and decrease the number of manual fraction of inspired oxygen (FiO2) adjustments as compared to manual weaning of oxygen therapy.
This clinical observational study investigates perioperative oxygen consumption and delivery in elderly patients undergoing major surgery. The primary objectives are to characterise the perioperative oxygen delivery, consumption and potential markers of oxygen debt. Secondary objective is to estimate the correlation between oxygen delivery/consumption and postoperative outcomes to guide the design of a future trial.
Carbon monoxide poisoning still places a burden on the healthcare system worldwide. While oxygen therapy is the cornerstone treatment, the role and practical modalities of hyperbaric oxygen therapy (HBO) remain controversial. This study aimed at comparing one session of HBO at 2 absolute atmosphere followed by 4 hours of normobaric oxygen therapy to 6 hours of normobaric oxygen therapy in adult victims of acute domestic carbon monoxide poisoning and without coma.
Maternal oxygen administration for concerning fetal heart rate tracing (FHT) patterns is common practice on Labor and Delivery units in the United States. Despite the broad use of oxygen, it is unclear if this practice is beneficial for the fetus. The purpose of this study is to compare oxygen to room air in patients with Category II fetal heart tracings with regard to neonatal acid-base status, subsequent tracings, and production of reactive oxygen species
The goal of this clinical research study is to compare high-flow oxygen, low-flow oxygen, high-flow air, and low-flow air in helping to decrease shortness of breath in cancer patients. Researchers also want to learn if these therapies can help to improve lung function and quality of life.
