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.
