title: [Effect of hypertensive shifts of arterial pressure on bronchial airway resistance].
abstract: Plethysmography of the cat body revealed that occlusion (for 1.5-2.0 min) of carotid arteries caused the hypertension in the major circulation to entail a 10% decrease in the airway resistance against air flow. Obturation of the aorta (for 1.5-2.0 min) caused the pressor of the arterial pressure to develop in conjugation with a 21% increase in the bronchial resistance. The data suggest that in both cases the above shifts of the respiration system are based on opposite changes in the lung congestion with blood (a decrease in the occlusion and an increase in the obturation) which affect the state of bronchi in the peripheral parts of the respiratory tract.
