Identical results were found in both systems: F<jats:sc>eco<\/jats:sc><jats:sub>2<\/jats:sub> was constant and independent of FGF with CO<jats:sub>2<\/jats:sub>\u2010absorption and constant V<jats:sub>e<\/jats:sub>, whereas rebreathing resulted in increasing F<jats:sc>eco<\/jats:sc><jats:sub>2<\/jats:sub> levels as FGF was decreased. As control of F<jats:sc>eco<\/jats:sc><jats:sub>2<\/jats:sub> in the rebreathing systems by regulating FGF could only take place within F<jats:sc>eco<\/jats:sc><jats:sub>2<\/jats:sub> levels higher than that determined by V<jats:sub>e<\/jats:sub> at complete CO<jats:sub>2<\/jats:sub>\u2010absorption, e. g. for the Hafnia A and D rebreathing systems, control of FGF necessitates relative hyperventilation. F<jats:sc>eco<\/jats:sc><jats:sub>2<\/jats:sub> with constant FGF decreased with increasing V<jats:sub>e<\/jats:sub> during CO<jats:sub>2<\/jats:sub>\u2010absorption, as well as during rebreathing, although this decrease was less in the rebreathing systems. Thus a decrease in F<jats:sc>eco<\/jats:sc><jats:sub>2<\/jats:sub> with rising V<jats:sub>e<\/jats:sub> can be avoided and hypocapnia prevented. The results agree with those obtained in clinical studies.<\/jats:p>","DOI":"10.1111\/j.1399-6576.1981.tb01664.x","type":"journal-article","created":{"date-parts":[[2009,1,1]],"date-time":"2009-01-01T10:10:52Z","timestamp":1230804652000},"page":"344-348","source":"Crossref","is-referenced-by-count":0,"title":["Control of Carbon Dioxide in Modified Mapleson A and D (Hafnia) Anaesthetic Systems.
