dopplex

RD2 Bi-directional Doppler

and PPG System

Four application areas in one unit:

• DVT Screening

• CVI Screening

• ABPI measurements

• Fetal heart detection

Dopplex RD2 handheld unit combines

Digital Photoplethysmography (PPG)

with Bi-directional Doppler to make a

complete arterial and venous

assessment system. It can provide

printouts of venous reﬁll curves and

blood ﬂ

ow waveforms using Dopplex

DR3 software or the Dopplex Printa II

package.

DVT Scr

eening with the Dopplex RD2

The Dopplex RD2 unit has been clinically pr

oven to be

effective in screening patients for the absence of a Deep

ein Thr

ombosis (DVT) in the lower limb.

Clinical studies have shown that Dopplex RD2 is a r

eliable

screening tool in patients with suspected lower limb DVT

and is suitable for bedside and community based

practice.

(Tan et al, 1999; Hennings et al, 2000)

Recent studies have shown that when the Dopplex RD2

is used in conjunction with D-Dimer, 100% NPV for DVT is

obtained. This has also resulted in signiﬁcant cost savings

for the hospital by reducing the number of Duplex scans.

ovey et al, 2000; W

illiams et al, 2002)

The RD2 unit is ideal for A&E departments, Medical

Assessment Units, GP and Leg Ulcer Clinics.

CVI Screening with the Dopplex RD2

The Dopplex RD2 unit can also be used for assessing

Chronic Venous Insufﬁciency (CVI).

Applications include:

• Rapid assessment of overall venous function.

(McEnroe

et al, 1988)

• Differentiation between deep and superﬁcial venous

insufﬁciency

(Neumann et al, 1992)

• Measurement of ABPI

• Detecting Fetal heart beat (with optional OP2)
