• metabolic
  • An indirect calorimeter for calculating the metabolic rate of a subject by measuring the oxygen consumption during respiration over a period of time includes a gas flow meter providing output electric signals to a microprocessor which drives a display and printer. (google.com)
  • The difference in volume between the inhaled gas and the exhaled gas is proportional to the oxygen consumption of the subject and the microprocessor integrates that signal over the time of the test, and multiplies it by a constant to provide a metabolic rate display. (google.com)
  • This invention relates to indirect calorimeters for measuring metabolic rate on the basis of respiratory oxygen consumption and more particularly to such a calorimeter which scrubs the CO 2 from the exhaled gas and computes the difference between the inhaled gas volume and the volume of the scrubbed exhaled gas to calculate oxygen consumption. (google.com)
  • Other hospital situations in which the measurement of rate of metabolic oxygen consumption is important include the adjustment of parental feedings for infants, and the control of respiratory gases during surgical operations. (google.com)
  • Our measurements can resolve differences in oxygen concentrations between different regions of individual cells, between different cell types, and also based on what metabolic pathways the cells use. (diva-portal.org)
  • Both octanoic acid and oleic acid stimulated oxygen consumption to a similar degree during hypothermic perfusion suggesting that the detrimental effect of octanoic acid was due to direct metabolic stimulation rather than uncoupling of oxidatative phosphorylation. (wikipedia.org)

  • gills
  • hypothetical devices to allow a human to take in oxygen from surrounding water Artificial gills are unproven conceptualised devices to allow a human to be able to take in oxygen from surrounding water. (wikipedia.org)
  • Natural gills work because nearly all animals with gills are thermoconformers, so they need much less oxygen than a thermoregulator of the same size. (wikipedia.org)
  • temperature
  • The oxygen uptakes of adult beetles increased at each experimental temperature as the seasons progressed from winter to spring. (oregonstate.edu)
  • Fuhrman showed that slices of rat kidney cortex and brain withstood cooling to 0.2 °C for one hour at which temperature their oxygen consumption was minimal. (wikipedia.org)
  • primarily
  • Further analysis of the ideal cycle indicated that the end-systolic P-V relationship (ESPVR) is an approximation to the adiabatic P-V trajectory that primarily determines total energy consumption. (biomedsearch.com)
  • processes
  • In recovery, oxygen (EPOC) is used in the processes that restore the body to a resting state and adapt it to the exercise just performed. (wikipedia.org)
  • vertebrates
  • Per unit volume, there is much more oxygen in air than in water, and vertebrates are active animals with a high energy requirement compared to invertebrates of similar sizes. (wikipedia.org)
  • concentration
  • At higher altitudes and in warmer climates the oxygen concentration in the air is lower compared to low altitude or colder climate. (wikipedia.org)
  • higher
  • In MCF-7 breast cancer cells, higher oxygen consumption can be detected when they rely on glutamine instead of glucose as their main metabolite, predominantly undergoing oxidative phosphorylation rather than glycolysis. (diva-portal.org)

  • widely
  • citation needed] in fact, the term "oxygen debt" is still widely used to this day. (wikipedia.org)
  • The most widely used criterion for confirming attainment of o 2 max is a levelling off (plateau) in oxygen consumption at o 2 max , yet the magnitude of this plateau used varies among scientists. (bmj.com)
  • Duration
  • Breath-hold duration is limited by oxygen reserves, and the risk of hypoxic blackout, which has a high associated risk of drowning. (wikipedia.org)
  • less
  • A person that is more fit will be able to consume the same amount of oxygen with fewer heartbeats than a less fit person. (zanran.com)
  • active
  • The Devonian saw increasing oxygen levels which opened up new ecological niches by allowing groups able to exploit the additional oxygen to develop into active, large-bodied animals. (wikipedia.org)
  • They are generally thought to be unwieldy and bulky, because of the massive amount of water that would have to be processed to extract enough oxygen to supply an active diver, as an alternative to a scuba set. (wikipedia.org)
  • temperatures
  • Oxygen uptakes of Douglas-fir beetles collected during November 1969 through April 1970 were measured at different experimental temperatures. (oregonstate.edu)
