Abstract

See full text

Embodiments of the present invention provide an extra corporeal membrane oxygenation circuit, wherein a pump communicates blood from a patient to an oxygenator and thence back to the patient, comprising: (a) a medium diameter venous line configured to accept blood from the patient and communicate the blood to the pump; (b) a medium diameter arterial line configured to accept blood from the oxygenator and communicate the blood to the patient; (c) one or more shunts connected in a series, where each shunt comprises a medium diameter input connected to a medium diameter output, where the medium diameter output is configured to connect to a medium diameter input of a successive shunt; a small diameter outlet between the medium diameter input and the medium diameter output; and a stopcock connected to the small diameter output such that flow out of the small diameter outlet can be controlled by the stopcock; wherein a first of such shunts is connected to accept blood from the venous line in parallel with the pump and wherein a last of such shunts is connected to communicate blood to the arterial line.
