ABSTRACT
Essential physiology When thinking about the effects of implanted catheters present in the blood stream in venous blood vessels, we should also consider the specific dynamics of the flow of blood occurring naturally in the blood vessels in which the infusion is taking place. There is very little information available in published literature concerning the flow rates within the major venous vessels used for infusion in the various laboratory animal species. Therefore, blood pressure has been chosen as the marker for relative blood flows in these vessels (Table 3.1).
