Regional lung ventilation in humans during hypergravity studied with quantitative SPECT

Regional lung ventilation in humans during hypergravity studied with quantitative SPECT

Highlights • Hypergravity causes arterial desaturation in humans. • Hypergravity causes anti-gravitational redistribution of lung perfusion. • We study ventilation during hypergravity using Technegas and SPECT. • The results show a redistribution of ventilation in the same direction as perfusion. •...

Description
Summary:Highlights • Hypergravity causes arterial desaturation in humans. • Hypergravity causes anti-gravitational redistribution of lung perfusion. • We study ventilation during hypergravity using Technegas and SPECT. • The results show a redistribution of ventilation in the same direction as perfusion. • We suggest that desaturation is caused by quantitatively different redistributions of regional perfusion and ventilation.
