Here Q is the cardiac output of the heart, C a O 2 is the arterial oxygen content, and C v O 2 is the venous oxygen content. (C a O 2 – C v O 2) is also known as the arteriovenous oxygen difference. The Fick equation may be used to measure V̇O 2 in critically ill patients, but its usefulness is low even in non-exerted cases. [8]
The VOC Solvents Emissions Directive was the main policy instrument for the reduction of industrial emissions of volatile organic compounds (VOCs) in the European Union. It covers a wide range of solvent-using activities, e.g. printing, surface cleaning, vehicle coating, dry cleaning and manufacture of footwear and pharmaceutical products.
E.g., multiplying the proposed population mean of approximately / acetone in end-tidal breath by the partition coefficient = at body temperature grossly underestimates observed (arterial) blood levels spreading around /. Furthermore, breath profiles of acetone (and other highly soluble volatile compounds such as 2-pentanone or methyl acetate ...
The Protocol to the 1979 Convention on Long-Range Transboundary Air Pollution Concerning the Control of Emissions of Volatile Organic Compounds or Their Transboundary Fluxes (known as the Volatile Organic Compounds Protocol or the VOC Protocol) is a protocol to the Convention on Long-Range Transboundary Air Pollution which aims to provide for the control and reduction of emissions of volatile ...
In absence of such, estimates of residual volume have been prepared as a proportion of body mass for infants (18.1 ml/kg), [12] or as a proportion of vital capacity (0.24 for men and 0.28 for women) [13] or in relation to height and age ((0.0275* Age [Years]+0.0189*Height [cm]−2.6139) litres for normal-mass individuals and (0.0277*Age [Years ...
An occupational exposure limit is an upper limit on the acceptable concentration of a hazardous substance in workplace air for a particular material or class of materials. It is typically set by competent national authorities and enforced by legislation to protect occupational safety and health.
An infrared spectroscopy correlation table (or table of infrared absorption frequencies) is a list of absorption peaks and frequencies, typically reported in wavenumber, for common types of molecular bonds and functional groups.
In general, molecules that are more oxidized (e.g., glucose) require less oxygen to be fully metabolized and, therefore, have higher respiratory quotients. Conversely, molecules that are less oxidized (e.g., fatty acids) require more oxygen for their complete metabolism and have lower respiratory quotients.
