CONTACTLESS PNEUMOGRAPHY OF SMALL LABORATORY ANIMALS AND A METHOD FOR QUANTITATIVE DETERMINATION OF THEIR PULMONARY VENTILATION
Abstract
Pneumography is used extensively both in experiments and in clinicophysiological examinations. From the pneumograms it is possible to assess the nature and regulation of external respiration under normal conditions as well as changes in the presence of various pathological conditions and under the influence of various agents on the organism. However, while in man and large animals the recording of respiratory excursions can be readily made, in small laboratory animals pneumography is technically difficult to perform and furthermore it involves immobilization of the animals which distorts normal breathing. Yet small laboratory animals are used the most to set up various experimental models of pathological processes (including those in the bronchi and lungs) and for dynamic investigation of respiratory functions under such conditions, which is extremely desirable. It is now possible to perform pneumography on small laboratory animals (mice, rats, guinea pigs and others) with equal ease, while they are not immobilized.
