Oxygen Portable Concentrator During Exercises in Patients With COPD

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 equa...

Prospective Study Comparing Different Modalities of Oxygen Delivery During Assessment of Functional Exercise Capacity

Objectives: The objective of this study is to determine if any differences exist between the varying modes of portable oxygen delivery systems including liquid oxygen, a portable concentr...

Effects of Different Oxygen Devices in Hypoxemic COPD Patients

Taken recent literature together, there is a sufficient number of trials investigating the effect of different oxygen devices. However, studies comparing oxygen delivery via portable oxyge...

Portable Oxygen Concentrator Signal Capture Study

The main purpose of this study is to learn how patients breathe on portable oxygen concentrators (POCs), and to get feedback from patients using POCs.

Effect of Oxygen in Normoxaemic COPD Patients Who Desaturate During Exercise

In COPD patients with desaturation during exercise, several studies have shown an acute beneficial effect of supplemental oxygen. Therefore, both the British Thoracic Society and the Ameri...

Impact of Supplemental Oxygen on Obstructive Sleep Apnea of Infants.

Treatment options may be limited for infants with obstructive sleep apnea when there is no surgically correctable upper airway lesion. We therefore evaluated, retrospectively, the efficacy of low-flow...

Effect of localized hypoxia on Drosophila embryo development.

Environmental stress, such as oxygen deprivation, affects various cellular activities and developmental processes. In this study, we directly investigated Drosophila embryo development in vivo while c...

Three decades of transtracheal oxygen therapy: A review of the associated complications with an illustrative case presentation.

Transtracheal oxygen therapy is a well-established modality for improving oxygenation in patients with chronic obstructive pulmonary disease, sleep apnea, pulmonary fibrosis, and other conditions caus...

Topical oxygen therapy promotes the healing of chronic diabetic foot ulcers: a pilot study.

Interventions that can heal or reduce diabetic foot ulcer (DFU) size may reduce the incidence of infection and amputation, and reduce associated social and economic costs. Many chronic wounds exhibit ...

Domiciliary High-Flow Nasal Cannula Oxygen Therapy for Stable Hypercapnic COPD Patients: A Multicenter, Randomized Crossover Trial.

A growing evidence base suggests a benefit of using high-flow nasal cannula oxygen therapy (HFNC) in the acute setting. However, the clinical benefit of domiciliary use of HFNC in patients with chroni...

Medical and Biotech [MESH] Definitions

A respiratory stimulant that enhances respiration by acting as an agonist of peripheral chemoreceptors located on the carotid bodies. The drug increases arterial oxygen tension while decreasing arterial carbon dioxide tension in patients with chronic obstructive pulmonary disease. It may also prove useful in the treatment of nocturnal oxygen desaturation without impairing the quality of sleep.

The rate at which oxygen is used by a tissue; microliters of oxygen STPD used per milligram of tissue per hour; the rate at which oxygen enters the blood from alveolar gas, equal in the steady state to the consumption of oxygen by tissue metabolism throughout the body. (Stedman, 25th ed, p346)

A large increase in oxygen uptake by neutrophils and most types of tissue macrophages through activation of an NADPH-cytochrome b-dependent oxidase that reduces oxygen to a superoxide. Individuals with an inherited defect in which the oxidase that reduces oxygen to superoxide is decreased or absent (GRANULOMATOUS DISEASE, CHRONIC) often die as a result of recurrent bacterial infections.

Stable oxygen atoms that have the same atomic number as the element oxygen, but differ in atomic weight. O-17 and 18 are stable oxygen isotopes.

Molecules or ions formed by the incomplete one-electron reduction of oxygen. These reactive oxygen intermediates include SINGLET OXYGEN; SUPEROXIDES; PEROXIDES; HYDROXYL RADICAL; and HYPOCHLOROUS ACID. They contribute to the microbicidal activity of PHAGOCYTES, regulation of signal transduction and gene expression, and the oxidative damage to NUCLEIC ACIDS; PROTEINS; and LIPIDS.
