Improved computation of respiratory resistance as measured by transiently increased resistance.
The authors have previously described an automated system for measuring total respiratory resistance. The technique used by this system involves a transient, externally applied increase in resistance to breathing. The utility of this technique is limited by a number of assumptions and to free it from the constraints imposed by one of these assumptions a new method for analysing the data was developed. The paper describes the new method of analysis and presents data comparing the resulting Rrss with those computed using the old method.
