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...

Portable Oxygen Concentrator Improvements to Physical Activity, Oxygen Usage, and Quality of Life in Chronic Obstructive Pulmonary Disease Patients Using Long-term Oxygen Therapy (POC-STEP)

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 a...

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.

Oxygen versus air-driven nebulisers for exacerbations of chronic obstructive pulmonary disease: a randomised controlled trial.

In exacerbations of chronic obstructive pulmonary disease, administration of high concentrations of oxygen may cause hypercapnia and increase mortality compared with oxygen titrated, if required, to a...

Topical oxygen therapy stimulates healing in difficult, chronic wounds: a tertiary centre experience.

Oxygen plays a central role in wound healing. Recent technological advances have miniaturised oxygen delivery systems, with novel topical oxygen therapy allowing patients to receive oxygen therapy 24 ...

Effectiveness of Hyperbaric Oxygen Therapy for the Management of Chronic Osteomyelitis: A Systematic Review of the Literature.

Hyperbaric oxygen has been used as an adjunctive measure in the treatment of chronic osteomyelitis. The aim of this systematic literature review was to analyze the outcome and the complications of hyp...

STABLE OXYGEN ISOTOPES IN WATER OF CONCENTATED LIQUID FOODSTUFFS: ARE THE COMMONLY DETERMINED VALUES ACCURATE?

Oxygen isotope analysis of water molecules of liquid foodstuffs is commonly performed under isotopic equilibrium between water in the solution and the vapour water, assuming that the liquid water acti...

Enzymatic glucose/oxygen biofuel cells: Use of oxygen-rich cathodes for operation under severe oxygen-deficit conditions.

A glucose/oxygen biofuel cell (BFC) that can operate continuously under oxygen-free conditions is described. The oxygen-deficit limitations of metabolite/oxygen enzymatic BFCs have been addressed by u...

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.
