The objectives s of the research were to study and define the factors which govern the motion of the thoraco-abdominal system and which contribute to the total opposition to ventilation of the lungs. A summary of the experimental program is presented. Topics include 1 Early experiments 2 Studies using analog computers 3 Critical tracheal volume-flow in dogs and infants 4 Atrial and esophageal pressure measurements in forced respiration 5 Mechanical aspects of panting as a respiratory maneuver 6 Respiratory dynamic resistance 7 Evaluation of the equation of motion of the respiratory system 8 Interpretation of respiratory pressure-volume Lissajous figures 9 Changes of thoraco-abdominal resonant frequency with driving pressure and 10 Status of research at time of this report.
