investigation. Tilt the transducer at approximately 45 degrees to the vessel. Arteries give a high pitched
pulsatile sound with veins giving a sound like a roaring wind. The optional headset helps to eliminate
ambient noise, making it easier to detect the weaker signals.
It also usual for the V2000 to be used in association with a pressure cuff and sphygmomanometer to
indicate the location and extent of arterial occlusion in the form of ankle/brachial pressure index and
segmental pressures.
Due to the variation of leg blood pressure over a wide range with the systemic pressure, the actual
values are less useful than the pressure index, which relates the ankle pressure to the pressure obtained
at the brachial artery. Using the V2000 to measure both pressures will ensure compatibility. In cases
where patients have peripheral arterial disease using the V2000, due to its high sensitivity, can be the
only technique suitable for the measurement of leg blood pressure.
Pressure Index =
Normal - ankle systolic pressure > brachial pressure.
Normal pressure index >1
Abnormal pressure index <1
After each use carefully wipe excess coupling gel from the transducer with a soft tissue. Never use
alcohol or any other solvent to clean any part of the Pocket Doppler, as these may cause damage. If
cleaning becomes necessary wipe the Pocket Doppler with a damp cloth moistened with a mild detergent.
The transducer face is very delicate and may be damaged by dropping.
Always clip the transducer in its holder when not in use.
In the unlikely event of instrument failure, the following simple checks may be made before contacting
your supplier for further advice.
Turn the volume control to maximum.
Turn the unit on and observe the Battery Low indicator, if it does not illuminate, replace the battery and
try again.
If the Battery Low indicator remains on, replace the battery and try again.
If the Battery Low indicator illuminates and then goes out (normal operation) stroke the transducer
face. If no audio signal is heard in the loudspeaker consult your supplier.
When contacting your supplier with a problem please have available the instrument type and serial
number. The serial number can be found inside the battery compartment.
Care has been taken through the design and manufacturing processes to minimise the EM emissions
that may be produced by this equipment. However, in the unlikely event that the unit causes an EM
disturbance to adjacent equipment, we suggest that the procedure is carried out 'out of range' of the
affected equipment.
If the user has any doubt regarding the unit's EM immunity during routine operation, we suggest that
the source of EM disturbance is identified and its emissions reduced.
If the user has any doubt regarding the identification and resolution of adverse EM conditions, they
may contact the following to seek advice
