Webreduces the ability to decrease the intrathoracic volume during expiration, reducing the pressure gradient for air to be expelled from the lungs into the atmosphere (this can result in a build-up of CO 2 known as hypercapnia). As a result, patients with advanced neuromuscular disease often require ventilatory support. WebSep 27, 2024 · Pulsus paradoxus is an abnormal decline (>10 mmHg) in systemic arterial pressure during inspiration. Normally, the intrathoracic pressure decreases during inspiration which allows blood to flow easily into the right heart. Conversely, the left heart filling decreases during inspiration, as the intrapericardial volume is fixed.
