Dynamic characteristics of oxygen consumption [PDF]

BioMedical Engineering OnLine, 2018
Previous studies have indicated that oxygen uptake ([Formula: see text]) is one of the most accurate indices for assessing the cardiorespiratory response to exercise. In most existing studies, the response of [Formula: see text] is often roughly modelled as a first-order system due to the inadequate stimulation and low signal to noise ratio.

Drivers of summer oxygen depletion in the central North Sea [PDF]

, 2016
In stratified shelf seas, oxygen depletion beneath the thermocline is a result of a greater rate of biological oxygen demand than the rate of supply of oxygenated water. Suitably equipped gliders are uniquely placed to observe both the supply through the

Bottom mixed layer oxygen dynamics in the Celtic Sea [PDF]

, 2020
The seasonally stratified continental shelf seas are highly productive, economically important environments which are under considerable pressure from human activity.

Metabolically exaggerated cardiac reactions to acute psychological stress revisited [PDF]

, 2009
The reactivity hypothesis postulates that large magnitude cardiovascular reactions to psychological stress contribute to the development of pathology. A key but little tested assumption is that such reactions are metabolically exaggerated.

ADENOSINE ON MYOCARDIAL OXYGEN CONSUMPTION [PDF]

British Journal of Pharmacology, 1976
A 3 min intracoronary infusion of adenosine (50 μg/min) produced a significant decrease in coronary artery perfusion pressure, left ventricular systolic pressure and myocardial O2 consumption in the isolated supported heart preparation of the dog perfused at a constant coronary blood flow.

The effects on arterial haemoglobin oxygen saturation and on shunt of increasing cardiac output with dopamine or dobutamine during one-lung ventilation [PDF]

, 2004
Publisher's copy made available with the permission of the publisher © Australian Society of AnaesthetistsTheoretically, if the cardiac output were increased in the presence of a given intrapulmonary shunt, the arterial saturation should improve as the ...

Variable sediment oxygen uptake in response to dynamic forcing [PDF]

, 2010
Seiche-induced turbulence and the vertical distribution of dissolved oxygen above and within the sediment were analyzed to evaluate the sediment oxygen uptake rate (JO2), diffusive boundary layer thickness (δDBL), and sediment oxic zone depth (zmax) in ...

THE OXYGEN CONSUMPTION OF HUMAN ERYTHROCYTES [PDF]

Archives of Internal Medicine, 1919
The earlier work on the respiratory metabolism of the blood itself was in large part rendered valueless because of lack of knowledge of the growth of micro-organisms, the effects observed being merely due to bacterial action. 1 It has been shown, however, by Warburg, and by Morowitz and his pupils, that each of the principal formed elements of the ...

Oxygen supply and consumption in soilless culture: evaluation of an oxygen simulation model for cucumber [PDF]

, 2001
A soil oxygen simulation model (OXSI) was tested and evaluated for evaluating growing media with respect to aeration. In the model, local oxygen concentrations are calculated from coefficients of diffusion and consumption (respiration), assuming ...

Scaling-up vaccine production: implementation aspects of a biomass growth observer and controller [PDF]

, 2009
This study considers two aspects of the implementation of a biomass growth observer and specific growth rate controller in scale-up from small- to pilot-scale bioreactors towards a feasible bulk production process for whole-cell vaccine against whooping ...
