Ultra-protective ventilation and hypoxemia
Partial extracorporeal CO2 removal allows a decreasing tidal volume without respiratory acidosis in patients with acute respiratory distress syndrome. This, however, may be associated with worsening hypoxemia, due to several mechanisms, such as gravitational and reabsorption atelectasis, due to a decrease in mean airway pressure and a critically low ventilation-perfusion ratio, respectively. In...
متن کاملPulmonary arteriovenous fistula: mechanical ventilation and hypoxemia.
Pulmonary arteriovenous malformation (PAVM) is an uncommon congenital anomaly. As PAVM is a direct communication between branches of the pulmonary artery and vein, major disturbances in gas exchange can result. We present a patient with an unsuspected PAVM who came to our institution for drainage of a brain abscess. Arterial blood gas analysis during and after surgery demonstrated a large alveo...
متن کاملApproaches to hypoxemia during single-lung ventilation.
Modern techniques to isolate the lungs, coupled with accurate continuous non-invasive monitoring, have made single-lung ventilation safe and easy to perform. Most patients maintain an adequate arterial oxygen tension during single-lung ventilation. In order to maximize oxygenation, efforts are directed towards optimizing perfusion and ventilation to the ventilated lung or increasing the oxygen ...
متن کاملNoninvasive ventilation for post-pneumonectomy severe hypoxemia.
ARDS remains a lethal complication after major lung resections. The reported mortality ranges from 50% to 100%, with increased incidence and mortality rates in pneumonectomy patients. The pathogenesis of early ARDS is still not fully understood, and the majority of patients will require mechanical ventilation. A review of the literature reveals that the role of noninvasive ventilation (NIV) in...
متن کاملCase scenario: Management of intraoperative hypoxemia during one-lung ventilation.
H YPOXEMIA that may reasonably be defined by an arterial hemoglobin oxygen saturation of less than 90% occurs in 5–10% of patients during one-lung ventilation (OLV). The physiopathology of hypoxemia is complex, and the management of intraoperative hypoxemia during OLV remains a challenge for anesthesiologists. In life-threatening hypoxemia, correct oxygenation should be restored rapidly. This m...
