Statistical modelling of human blood carbon dioxide partial pressure.
This paper deals with statistical modelling of blood carbon dioxide partial pressure pCO2. The clinical measurements were carried out in the Arab Centre for Heart and Special Surgery in Amman. The statistical analysis of the results obtained demonstrates that pCO2 for arterial, venous and capillary blood have histograms approaching normal ones. Moreover, the experimental data suggest that the b...
متن کاملNitrogen and carbon dioxide adsorption by soils.
High-resolution nitrogen (77 K) and carbon dioxide (273 K) adsorption at subatmospheric pressures has been studied for a range of model soils of various origins with different organic matter (OM) contents. It is demonstrated that N2 and CO2 molecules probe different regions of soil particles. Nitrogen is adsorbed primarily on the outer surface of soil particles, while CO2 has a higher affinity ...
متن کاملCarbon dioxide and oxygen partial pressure in expiratory water condensate are equivalent to mixed expired carbon dioxide and oxygen.
This study was to determine whether the PCONCO2 and PCONO2 which collect in the expiratory trap of a ventilator circuit are equivalent to PECO2 and PEO2. Fifty studies were performed in 34 mechanically ventilated male patients. Five milliliters of condensate fluid were collected and PECO2 and PEO2 were measured. Exhaled gases were collected simultaneously with condensate fluid for 5 min in a me...
متن کاملConcordance between side-stream end-tidal carbon dioxide and arterial carbon dioxide partial pressure in respiratory service setting.
OBJECTIVE To explore the correlation and concordance between end-tidal carbon dioxide and arterial carbon dioxide partial pressure, and confirm the experience of the general consensus among service environments. DESIGN A prospective cross-sectional analysis. SETTING Two respiratory service units in Hong Kong. PARTICIPANTS Two hundred respiratory patients were recruited, in whom 219 sets o...
متن کاملConcordance between side-stream end-tidal carbon dioxide and arterial carbon dioxide partial pressure in respiratory service setting
Non-invasive monitoring of arterial oxygen using percutaneous pulse oximetry is well established. Although some studies show a good correlation of transcutaneous end-tidal carbon dioxide partial pressure (PetCO2) with arterial carbon dioxide partial pressure (PaCO2), they were performed in research settings and involved restricted populations such as paediatric, accident and emergency, or inten...
