A SYSTEM FOR THE CONTINUOUS MEASUREMENT OF OXYGEN UPTAKE AND CARBON DIOXIDE OUTPUT IN ARTIFICIALLY VENTILATED PATIENTS

Carbon Dioxide Effects on Fruit Respiration. I. Measurement of Oxygen Uptake in Continuous Gas Flow.

Carbon dioxide elimination and oxygen consumption in mechanically ventilated children.

BACKGROUND Accurate measurement of carbon dioxide elimination (V̇CO2 ) and oxygen consumption (V̇O2 ) at the bedside may help titrate nutritional and respiratory support in mechanically ventilated patients. Continuous V̇CO2 monitoring is now available with many ventilators. However, because normative data are sparsely available in the literature, we aimed to describe the range of V̇CO2 and V̇O2 valu...

Measurement and Modeling of Acridine Solubility in Supercritical Carbon Dioxide

Supercritical carbon dioxide has gained increasing attention in food and pharmaceutical processing owing to the fact that it is environmentally inexpensive, not flammable, essentially non-toxic, and it has a convenient critical point. Also, it has been attracting much attention in many fields, such as extraction of sensitive materials and pharmaceutical processing and polymerization processes. ...

correlation of end-tidal carbon dioxide with arterial carbon dioxide in mechanically ventilated patients

background: patients undergone mechanical ventilation need rapid and reliable evaluation of their respiratory status. monitoring of end-tidal carbon dioxide (etco2) as a surrogate, noninvasive measurement of arterial carbon dioxide (paco2) is one of the methods used for this purpose in intubated patients. objectives: the aim of the present trial was to study the relationship between end-tidal c...

Cardiac output measurement in ventilated lambs with a significant left-to-right shunt using the modified carbon dioxide fick method.

BACKGROUND It remains a great challenge to measure systemic blood flow in critically ill newborns. In a former study we validated the modified carbon dioxide Fick (mCO(2)F) method for measurement of cardiac output in a newborn lamb model. In this new study we studied the influence of a left-to-right shunt on the accuracy of the mCO(2)F method. OBJECTIVE To analyze the influence of a left-to-r...
