WebJul 5, 2024 · If intrathoracic pressure is increased, one might expect this pressure to compress the thoracic aorta, which would tend to increase LV afterload. Others suggest the opposite: increased intrathoracic pressure will displace blood from the thoracic to the abdominal aorta and decrease afterload (13, 28). WebIn turn, the thoracic cavity and lungs decrease in volume, causing an increase in interpulmonary pressure. The interpulmonary pressure rises above atmospheric pressure, creating a pressure gradient that causes …
