Summary
With the aid of electrodes located at the end of a catheter introduced into the lungs through the bronchi or blood vessels, a measurements was made of the electric resistance of the lungs with a subsequent separation of the useful signal into the ohmic and capacitance components. A block diagram is presented and a brief description is given of the main elements of the instrument. Some problems concerning the equivalent electric circuit diagram of the object, as well as of the accuracy and the range of measurements are discussed.
Some practical results concerning the clinical use of this method are presented.
