title: [Tonus of respiratory muscles in acetycholine hypotonia (author's transl)].
abstract: The importance of respiratory muscles in relation to circulation and ventilation was investigated in acute hypotonia after acetylcholin injection. The tonus of respiratory muscles was assessed by measuring the circumference of chest and abdomen. Changes of volume of the body cavities were examined by body plethysmography. A significant relation between the increase of circumferences of the chest and abdomen and increase of lung volume was registered. The authors conclude, that the tonus of the respiratory muscles determines the volume of chest and abdomen and influences the distribution of blood.
