Extracorporeal Membrane Oxygenation (ECMO) is a life-saving therapy usedfor support in critical heart and/or lung failure. Patients blood is pumped viaan artificial lung for oxygenation outside of the body. The circuit is composedof a blood pump, cannulae for drainage and reinfusion, a membrane lung,tubing and connectors. Its use is associated with thromboembolic complicationsand hemolytic damage. Detailed numerical studies of two blood pumps anda lighthouse tip drainage cannula were undertaken to characterize the flowstructures in different scenarios and their link to platelet activation. The pumpsimulations were modelled according to manufacturers proclaimed use but alsoin off-design conditions with flow rates used in adult and neonatal patients.Lagrangian Particle Tracking (LPT) was used to simulate the injection ofparticles similar in size to platelets to compute platelet activation state (PAS).The results ...

Normal cardiac output is 4-8 L/min. Normal cardiac index is 2.5-4 L/min/m2. Normal stroke volume is 60-100 ml/beat. Normal stroke volume index is 33-47 ml/beat/m2. A Low CO/CI may be observed with hypovolemia, hypoperfusion, shock, arrhythmia, and severe metabolic acidosis. A High CO/CI may be observed with hypoxia, the use of positive inotropes, early septic shock and anemia. A Low SV/SVI may be observed with impaired LV contractility, acidosis, hypoxemia, hypercapnia, increased afterload, decreased preload and tachycardia. A High SV/SVI may be observed with bradycardia, the use of positive inotropes, and decreases in afterload ...

Aortopulmonary pressure difference and pulmonary blood flow velocity were studied during the first 48 hours of life in 12 premature neonates with severe respiratory distress syndrome (RDS), treated by natural surfactant, and in 25 premature neonates with mild RDS. A non-invasive Doppler ultrasound method was used to estimate aortopulmonary pressure difference and pulmonary blood flow velocity from the left pulmonary artery. Aortopulmonary pressure difference was significantly lower at 6 hours of age in the infants with severe RDS and was not increased one hour after surfactant therapy. Aortopulmonary gradient started to rise at 24 hours of age and was equal to that of neonates with mild RDS at 48 hours. Pulmonary blood flow velocity was significantly lower, initially ...
