Abstract
The respiration of anaesthetized pigeons, suffocated to death by tracheal occlusion, is followed by means of the intratracheal pressure tracing. A special procedure allows to distinguish expiratory from inspiratory efforts.
The overall expiratory effort about equals the inspiratory one. During the agony, however, the release of expiratory energies increases whereas inspiratory activity is vanishing more and more.
On the basis of the period of agony, a screening procedure is developed to search for substances which would selectively influence the release of expiratory or inspiratory energies respectively.
