Breath Alcohol Concentration and Breath Temperature
Breath alcohol concentration, breath temperature, and body temperature are used to extrapolate the breath alcohol concentration to the concentration of alcohol in the deep lung air, which is in equilibrium with the pulmonary blood. Introduction The variability that is seen in the breath alcohol test (note: “alcohol” means ethyl alcohol) has always been more or less ignored as inevitable “biolog...
متن کاملSingle 20-second acquisition of deep-inspiration breath-hold PET/CT: clinical feasibility for lung cancer.
UNLABELLED This study was designed to compare tumor (18)F-FDG uptake between a single 20-s acquisition of deep-inspiration breath-hold PET/CT and free-breathing PET/CT for lung cancer. METHODS Before the clinical study, a phantom study was performed to determine the optimum breath-hold time for the PET scan. We studied 47 patients with lung cancer who underwent free-breathing PET/CT with the ...
متن کاملMeasured breath.
Background: Pathogenic yersiniae (Y. pestis, Y. pseudotuberculosis, Y. enterocolitica) share a virulence plasmid encoding a type three secretion system (T3SS). This T3SS comprises more than 40 constituents. Among these are the transport substrates called Yops (Yersinia outer proteins), the specific Yop chaperones (Sycs), and the Ysc (Yop secretion) proteins which form the transport machinery. T...
متن کاملVisualising Breath
The visualising of breath using digital in-line holography is challenging due to the issues of the relative scale of the human breath in relation to the recording area of the hologram. In this collaborative project between artist Jayne Wilton and physicists Professor Peter Hobson and Dr Ivan Reid a number of approaches, including the use of spatial filtering (Hobson and Hong 1988), are being us...
متن کاملBreath-by-breath assessment of alveolar gas stores and exchange.
The volume of O(2) exchanged at the mouth during a breath (Vo(2,m)) is equal to that taken up by pulmonary capillaries (Vo(2,A)) only if lung O(2) stores are constant. The latter change if either end-expiratory lung volume (EELV), or alveolar O(2) fraction (Fa(O(2))) change. Measuring this requires breath-by-breath (BbB) measurement of absolute EELV, for which we used optoelectronic plethysmogr...
