The influence of strenuous breathing upon arterial blood flow was followed. In the majority of investigated patients the skin circulation (according to finger plethysmogram) and the circulation of muscle (according to electrical muscle activity) increased. The author concludes that strenuous inspiration diminishes the intrathoracic pressure, the venous blood is suctioned into the right heart and the drainage of veins in the extremities is method. The venous pressure is lowered, the pressure gradient in the capillaries increased and the arterial inflow improved.
