7-4. Pneumoplethysmograph 

With the PV-21, Smartdop senses volume changes in a limb or digit by measuring the 

pressure changes in a recording cuff. 
“How to use pneumoplethysmograph” is described in this section. 
Built-in cuff inflator works when INFLATOR in menu mode is ON to inflate cuff.   
See “§ 7-4-4. PV Mode Setting - INFLATOR” for details.

DC Coupling: 

Measurement of maximum venous outflow 

 

7-4-2. PV - Measurement of Maximum Venous Outflow 

Purpose 

Because deep venous occlusion cannot be diagnosed reliably on the basis of presenting 

signs and symptoms, pain and swelling being frequently due to other causes, objective 

screening tests are of value in confirming or ruling out suspected venous obstructions in 

the lower extremities. The test consists of first inducing temporary venous pooling by 

means of a constricting thigh cuff followed by measurement of the rapidity of emptying 

when the constricting cuff is suddenly vented. Measurement of maximum venous outflow 

is frequently employed as an adjunct to Doppler venous compression studies. 

 

Preparation 

(1) Connect the PV probe assembly (PV-21) the probe connector #1 or #2 of the main unit, 

and turn it on. 

 

(2) Make sure Mode 2 LED (DC mode) illuminates. If not, press MODE button to select 

Mode 2 for DC mode.
