2016年6月30日 · Venovenous extracorporeal membrane oxygenation (vv-ECMO) has been classically employed as a rescue therapy for patients with respiratory failure not treatable with conventional mechanical ventilation alone. In recent years, however, the timing of ECMO initiation has been readdressed and ECMO is often started earlier in the time course of respiratory …

2024年6月24日 · Algorithm to avoid hypoxia in V-V ECMO: Algorithm for preventing and managing hypoxia on V-V ECMO at the bedside. Both, patient as well as V-V ECMO factors must be optimized to improve oxygen supply to the tissue. Note, that increasing CO might lead to lower arterial oxygen saturation but still increase the oxygen supply to the patient.

2015年12月1日 · Venoarterial (VA) and venovenous (VV) extracorporeal membrane oxygenation (ECMO) support is increasingly being used in recent years in the adult population. Owing to the underlying disease precipitating severe respiratory or cardiac failure, echocardiography plays an important role in the management of these patients. Nevertheless, there are currently no …

2016年2月10日 · Veno–veno–arterial (VVA) ECMO may offer effective oxygenation and hemodynamic support without differential hypoxia by regulating the return of oxygenated blood to the underperfused coronary and cerebral circulation [3–5]. Therefore, VVA mode can be an alternative treatment modality for ARDS patients with severe septic shock.

2024年4月25日 · This final equation expresses delivery of oxygen on V-V ECMO as dependent only on hemoglobin, cardiac output, ECMO effective blood flow rate, and the body’s consumption of oxygen. Introducing beta-blocker therapy, then, irrespective of its effect on \({S}_{a}{O}_{2}\) , reduces delivery of oxygen through reduction of cardiac output if Hgb, EF ...

2014年1月21日 · Venovenous (VV)-ECMO may be initiated as a treatment strategy for patients with severe acute respiratory failure, including adult respiratory distress syndrome (ARDS) [1–5], as a salvage therapy for patients with profound gas-exchange abnormalities despite positive-pressure ventilation. Additionally, partial extracorporeal support systems ...

2019年8月7日 · We do not deny the clinical importance of hypoxemia in the pathophysiological context of ARDS as a VV ECMO indication, but certainly a more realistic approach should look beyond the classical criteria to start ECMO therapy and take into account the heart-lung interactions its effects and implications in the prognosis of patients with acute respiratory failure.

2024年10月8日 · Background Veno-venous extracorporeal membrane oxygenation (VV ECMO) has become standard of care in patients with the most severe forms of acute respiratory distress syndrome. However, hemolysis and bleeding are one of the most frequent side effects, affecting mortality. Despite the widespread use of VV ECMO, current protocols lack detailed, in-vivo …

2024年8月17日 · Objective Our study aimed to investigate the effects of different extracorporeal membrane oxygenation (ECMO) blood flow rates on lung perfusion assessment using the saline bolus-based electrical impedance tomography (EIT) technique in patients on veno-venous (VV) ECMO. Methods In this single-centered prospective physiological study, patients on VV ECMO …

2018年6月15日 · Extracorporeal membrane oxygenation (ECMO) is used in critically ill patients with severe pulmonary and/or cardiac failure. Blood is drained from the venous system and pumped through a membrane oxygenator where it is oxygenated. For pulmonary support, the blood is returned to the patient via a vein (veno-venous ECMO) and for pulmonary/circulatory …
