Abstract: | Themethanol-burning lung model has been used as a technique for generatinga predictable ratio of carbon dioxide production (CO2) to oxygen consumption(O2) or respiratoryquotient (RQ). Although an accurate RQ can be generated, quantitativelypredictable and adjustableO2 andCO2 cannot be generated. Wedescribe a new burner device in which the combustion rate of methanolis always equal to the infusion rate of fuel over an extended range ofO2 concentrations. This permitsthe assembly of a methanol-burning lung model that is usable withO2 concentrations up to 100% and provides continuously adjustable and quantitativeO2 (69-1,525 ml/min)and CO2 (46-1,016ml/min) at a RQ of 0.667. |
