(57) Abstract :
A blood flow control device comprising a flow influencing element arranged to be placed in the vena cava of a human during
cardiopulmonary resuscitation and controllable between a non-to-low-flow state in which the flow influencing element
substantially reduces a blood flow within the vena cava and a flow state in which the flow influencing element allows
substantially unreduced blood flow responsive to an existing or a predicted pressure difference between an upstream area and a
downstream area of the flow influencing element. The blood flow control device is capable of reducing retrograde blood flow
during the compression phase of CPR and thus improves the efficiency of CPR and blood perfusion. The blood flow control
device can also be used for the administration of drugs almost directly to the heart as well as for measuring physiological and
chemical properties such as blood gases.
