Estimating Neonatal Oxygen Consumption from Heart Rate

Psychophysiology, 1983
ABSTRACTThe relationship between heart rate (HR) and oxygen consumption (V̇o2) has been investigated in a sample of 20 low‐risk, term neonates aged 14–48 hrs. Repeated, simultaneous measurements of HR and V̇o2 were performed on each neonate during each of three epochs ordered by increasing level of activity.

[Study on Oxygen Consumption, Oxygen Consumption Rate and Asphyxiation Point of Poecilobdella manillensis].

Zhong yao cai = Zhongyaocai = Journal of Chinese medicinal materials, 2015
To investigate the oxygen consumption, oxygen consumption rate and asphyxiation point of Poecilobdella ma- nillensis.Oxygen consumption, oxygen consumption rate and asphyxiation point on juvenile (the average weight of 0. 29 g) and adult leech (the average weight of 2.89 g) of Poecilobdella manillensis were measured at water temperature conditions of ...

An innovative method to calculate oxygen consumption rate

Journal of Central South University, 2019
Based on heat and mass transfer characteristics of spontaneous combustion of coal, Arrhenius equation and the Ranz-Marshall correlation, a novel approach was proposed in this paper to estimate oxygen consumption rate of self-ignition of coal at high temperature.

The rate of consumption of oxygen by anthers of Tradescantia paludosa

Radiation Botany, 1964
Abstract The paper describes an adaptation of the Hersch technique for the micro-assay of oxygen which permits one to sample the oxygen content of the gas in a small enclosure containing some forty anthers, and thereby to evaluate the rate of consumption of oxygen by a known mass of anther tissue over a period of several hours and with varying ...

Comparative growth rates and oxygen consumption in young Galliformes

Comparative Biochemistry and Physiology Part A: Physiology, 1983
The high correlation between growth rate and adult body weight has been much more thoroughly documented for altricial birds than for precocial species. This paper gathers data from the literature for precocial Galliformes and also reports new growth data on six galliform species for analysis.

ESTIMATION OF THE IN VIVO OXYGEN CONSUMPTION RATE OF THE HUMAN CORNEAL EPITHELIUM*

American Journal of Optometry and Archives of American Academy of Optometry, 1972
&NA; Oxygen consumption rate of corneal epithelium must be known in order to estimate the effect of contact lenses, conventional or hydrophilic, on corneal metabolism. The in vivo measurements reported here were made with a polarographic oxygen sensor on

[Oxygen concentration, perfusion rate and cardiac oxygen consumption].

Fiziologicheskii zhurnal SSSR imeni I. M. Sechenova, 1992
The oxygen consumption by the heart did not depend on the oxygen contents in the perfusate. However, it was determined by the perfusion velocity (as a physical factor).

The Effect of Atropine on Heart Rate and Oxygen Consumption in the Hypoxic Fetus

Obstetric Anesthesia Digest, 1984
To determine if vagal blockade during hypoxic bradycardia improves fetal oxygenation, 10 studies were carried out on five chronically instrumented sheep after 0.8 week of gestation. At a mean maternal arterial oxygen tension of 33 +/- 4 mm Hg, the fetal heart rate decreased 20% to 137 +/- 19 bpm, and fetal oxygen consumption decreased 42% to 4.6 +/- 1 ...

Measuring rate of heat release by oxygen consumption

Fire Technology, 1991
This paper provides a comprehensive set of equations and guidelines to determine the rate of heat release in full-scale fire tests based on the O2 consumption principle. The approach is different from other investigators as the enphasis is on full-scale fire test applications and the use of volumetric flow rates is avoided.

[The effect of Sandimmun on the rate of oxygen consumption by lymphocytes].

Eksperimental'naia i klinicheskaia farmakologiia, 1995
Experiments on male Wistar rat thymocytes have demonstrated that cyclosporin A, an active substance of the immunodepressive agent sandimmune given in concentrations of 1 to 10 micrograms/ml, has no effects on cellular oxygen consumption rates measured by the polarographic technique by using a Clarke electrode.
