What happens to intrathoracic pressure during inspiration? Inspiration drops intrathoracic pressure, dilates the thoracic vena cava, and acutely decreases atrial filling. Cardiac output falls, and consequently arterial pressure falls. The drop in arterial pressure reduces stretch on the arterial baroreceptors, causing a reflex increase in heart rate. Why does BP decrease during inspiration? As the […]
