Reversible decrease of oxygen consumption by hyperoxia.
The hemodynamic and metabolic effects of 90 minutes normobaric hyperoxia were studied in 20 critically ill patients (11 septic, 9 nonseptic) requiring mechanical ventilation with inspired O2 fraction (FIO2) less than 0.40. Thirty minutes after increasing the FIO2 to 1.0, arterial PO2 had increased from about 100 to about 400 mm Hg, and whole body oxygen uptake (VO2) was decreased 10 percent (p ...
متن کاملOxygen toxicity: an introduction.
Although oxygen has been known to be toxic for more than 200 years, the clinical importance of oxygen toxicity was not appreciated until an epidemic of retrolental fibroplasia occurred in the early 1950s. Oxygen at high partial pressures is toxic to the respiratory, cardiovascular, nervous, and gastrointestinal systems. Toxicity results from the formation of oxygen-free radicals. These arise wi...
متن کاملFixpoint Computation: Leaking Gas Burner
Real-time distributed system speciication and veriication in asynchronous propositional temporal logic. Let A be the integrator system deened in Figure 5. We use the xpoint computation procedure to prove that the formula y 60 ! 20t y is an invariant of A. It follows that the gas burner leaks at most one twentieth of the time in any interval of at least 60 seconds. Let R i = hpc = 1 ^ t = 0 ^ x ...
متن کاملPredicted Decrease in Membrane Oxygen Permeability with Addition of Cholesterol.
Aberrations in cholesterol homeostasis are associated with several diseases that can be linked to changes in cellular oxygen usage. Prior biological and physical studies have suggested that membrane cholesterol content can modulate oxygen delivery, but questions of magnitude and biological significance remain open for further investigation. Here, we use molecular dynamics simulations in a first...
متن کاملExperimental and numerical investigations in the near-burner region of a versatile multi-fuel burner
An experimental and numerical investigation on the effect of swirl on the motion of coal particles in the near-burner region of a versatile multi-fuel swirl-stabilised laboratory burner of total thermal input of 100kW, has been performed. The burner was designed as a scale model of a lOMW coal burner operating in a cement rotary kiln, produces flames of different aerodynamic characteristics, an...
