Summary
Normal action potentials in respiratory muscles were studied. Then these were compared with action potentials observed in patients, chiefly those ill with bronchial asthma and pulmonary emphysema. It was noted that the muscles of the patients registered a marked rise in activity even when the usual external indicators such as rate, depth and pulmonary ventilation appeared to be near normal. This was taken to indicate that the respiratory center was belrg subjected to compensatory stimulation.
