The APG® Air Plethysmograph is the only system that measures true blood volume changes in milliliters and blood flow in milliliters per second.
The APG® system senses pressure changes in a large cuff that extends from knee to ankle, which is calibrated in milliliters using a calibration syringe.
The APG® Air Plethysmograph helps identify and follow-up patients that are good candidates for deep venous reconstruction. Also, as testing can be performed over compression garments, the effectiveness of elastic or non-elastic compression devices can be assessed and tailored to the individual patient. Other uses for the APG® include its use in selecting the best arm for dialysis access graft or AV fistula. Arterial inflow can be measured to identify patients that are the best candidates for drug therapy (such as synthetic prostacyclin) and for follow-up to vascular interventions.
A modified version of the APG® has been used on the Mir Space Station to quantify the effects of prolonged microgravity on peripheral vascular tone in arms and legs.
For those with an already basic knowledge of how to use the APG® System, download the printer-friendly APG® Advanced Course (PDF) for in-depth instructions.
