Hypothesis-generating for asphyxia-induced pulmonary changes; leaves open translation to human cardiovascular regulation.
Submersion asphyxia in ducks induces profound cardiovascular changes, including increased pulmonary vascular resistance and right heart enlargement, indicating active regulation of stroke volume.
Aakhus et al. (1964) studied Submersion asphyxia. Submersion vs. Presubmerged condition was evaluated on Circulation time, heart size, and vessel diameter. Submersion of unanesthetized ducks prolonged pulmonary circulation time by a factor of 4-5, increased total heart size, and reduced pulmonary artery diameters.
