This is the
specification for a Hokanson strain gauge
plethysmograph system suitable for arterial
inflow studies if customers want to use a
separate Data Acquisition System instead of the
recommended Hokanson NIVP3 software.
Arterial inflow is a
quantitative measurement used to non-invasively
measure the bloodflow rate in the limb. In the
normal case, arterial and venous flow in any
limb is equal on the average. Venous occlusion
plethysmography measures arterial inflow by
abruptly stopping venous outflow with a proximal
cuff inflated to above venous pressure, but
below arterial pressure (typically about 50
mmHg). This causes the volume of the limb to
increase due to arterial inflow. A
plethysmograph is used to measure the volume
change in the limb. The rate of change of the
volume, in percent per minute, is the arterial
flow rate at the moment of venous occlusion.
Often the flow rate is reported as being
cc's/100 cc's/minute. This is equivalent to
percent per minute.
