It was found that venous blood could be arterialized while flowing through a tubular silicone membrane surrounded by pure oxygen at 38°C. Carbon dioxide was found to be the limiting compo nent for adequate transfer. A mathematical model was derived to des cribe the transport of each gas. The model used to describe the oxygen absorption by blood flowing in a tubular membrane was assumed to be independent of the simultaneous carbon dioxide desorption. The carbon dioxide desorption was assumed to be dependent upon the oxygen absorption. A comparison of the theoretical models with the experi mental data indicated that the oxygen absorption model was optimistic in its prediction of the amount of oxygen transferred and the carbon dioxide model was found to be slightly conservative in its prediction of the amount of carbon dioxide transferred. The net result was a conservative prediction of the length of tubing needed to arterialize venous blood. It should be noted that both mathematical models were developed from theoretical concepts and no attempt was made to fit the experimental data with pseudo-diffusivities. An experimental study was also made to determine if pulse rate, for a given average flow rate, affected the mass transfer of oxygen and carbon dioxide in blood flowing in a permeable tube. It was con cluded that pulse rate had no appreciable effect on the transfer of either oxygen or carbon dioxide in the range studied. xiii A study of the variables which affect the transfer of oxygen and carbon dioxide in blood flowing in a permeable tube showed that the effect of the variables on oxygen and carbon dioxide were not the same. For a given tube length and flow rate, the tube exit dimensionless partial pressure of oxygen was significantly increased by in creasing the pH, decreasing the hemoglobin concentration or raising the tube inlet oxygen partial pressure. Oxygen absorption was a weaker function of tube wall thickness and hematocrit. Carbon di oxide desorption was greatly decreased by increased wall thickness, but it was only a very weak function of pH, hematocrit, and inlet oxygen partial pressure. The carbon dioxide desorption was inde pendent of tube inlet carbon dioxide partial pressure and the hemo globin concentration.","PeriodicalId":78333,"journal":{"name":"JAAMI : journal of the Association for the Advancement of Medical Instrumentation","volume":"5 4 1","pages":"230-42"},"PeriodicalIF":0.0,"publicationDate":"1971-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"69690351","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
