Shunt hipoxemia
WebJan 23, 2024 · As a result, right-to-left shunts result in more hypoxemia than hypercapnia. Generally, increasing FiO2 through supplemental oxygen therapy does not improve hypoxemia in patients with right-to-left shunts. The increased oxygen content of the inspired air never reaches the shunted blood for gas exchange. WebThe development of this syndrome requires two components: a shunt (interatrial or intrapulmonary) and a functional component that promotes abnormal shunting when the patient moves from a supine to an upright position. Platypnea-orthodeoxia syndrome is likely an under-recognized cause for dyspnea and positional hypoxia.

WebIn the newborn lamb, we have induced chronic hypoxemia by placing an inflatable balloon around the pulmonary artery after performing an atrial septostomy. Three days after surgery, the balloon was gradually inflated in 11 lambs to create a right-to-left atrial shunt such that arterial oxygen saturation was between 60 and 75%.
