OPERATING INSTRUCTIONS
uOpen the battery cover. Set a 9V alkaline square type battery in the unit ensuring that
the positive and negative electrodes correspond to the (+/-) marks on the battery box.
See Figure A
uConnect the probe with the small dot up on the probe connector (12 o’clock).
See Figure B
uDepress the probe button to turn the unit ON. See Figure C
uMake sure the power indicator on the
unit is ON. Turn the volume control to
minimum, then slowly turn the volume
up. See Figure D

uPut the ultrasonic gel on the probe top or on the patient’s skin.
uPut the probe on the measurement area and move it slowly to locate the point where
maximum Doppler sounds are heard. The at probe should be 90 degrees placed at
on the animal’s skin over vessel.
uConnect the headset when necessary. Headset can be used to listen to Doppler sounds.
It will cut o the MiniDop speaker to the room. See Figure E
uDepress the probe button again to turn the unit OFF. If the unit is left ON, the power
automatically shuts OFF in about 5 minutes. See Figure F

uIf the power indicator becomes dark, replace the battery with a new one. Use a 9V
alkaline battery only. See Figure G

DIRECTIONS FOR USE
IndirectArterialBloodPressureMonitoringwiththeDopplerUnit
uClip the palmer aspect of the foot just proximal to the metacarpal pad. It is important to clip
the fur as short as possible. Rub a small amount of ultrasound gel on the skin in the midline
area where the palmer arterial arch is located. It can be palpated on large dogs and is actually
just slightly medial to the midline.
uPlace a large “dollop” of ultrasound gel on the non-numbered side of the Doppler ow probe.
Place the probe in the location of the artery described in above and tap it in place tightly.
(Turn on the Doppler unit with the ow probe plugged into the unit. The ow probe should not
be frequently disconnected from the unit as this loosens the connectors and wires in the unit).
uEnsure that the unit is charged. A swishing sound should be heard each time blood ows
through the artery. If blood ow is not heard, use the probe as a locator and move it slightly
until the swishing sound is heard and then re-tape in place.
uMake a loop in the cord of the ow probe. Tape the cord to the foot/metacarpal loop right
over the tape used to xate the ow probe to the skin initially.
uThe blood pressure cu is now in place. The cu’s width should approximate the width and
be up to two times that of the forearm (mid-radial region). It is applied so that the mid-section
on the rubber blade inside the cu is directly over the posterior medial aspect (where the
radial artery is located). This can be located by digitally occluding the area and hearing the
swishing sounds of the Doppler stop indicating the artery is at that location because its ow
is now temporarily blocked.
uWhen the cu is applied the INDEX line on the end of the cu should fall within the RANGE
on the cu, which is diagrammed on the inside. If outside this range, the reading will be either
falsely low (with cus too big for the size of the limb it is surrounding) or falsely high (with the
cu too small). An estimate can be arrived and that will indicate how far o, in percentage,
the cu reading will be, taken by observing the amount of length of the indexed area.
uA small amount of adhesive tape is added around the cu to prevent it from popping the
Velcro and showing a falsely high reading.
uThe cu is inated by squeezing the rubber bulb with the air outlet nozzle closed until the
manometer reading is 20-30mm Hg above when the swishing sound stopped. The air-outlet
nozzle is slowly opened and the cu is allowed to slowly deate. When the swishing sound is
rst heard again, this marks the ow of blood through the artery corresponding to SYSTOLIC
PRESSURE on the sphygmomanometer. The sound should be a shorter choppier sound than
was heard when the cu was not inated.
uThe cu deation is continued slowly as the characteristics of the swishing sound are
carefully monitored. A light “backward” sound or diastolic “swish” sound is again heard (or
as it is again sounded prior to any cu ination) corresponding to DIASTOLIC PRESSURE
when a very mild amount of “backow” in the artery occurs. The diastolic pressure is not
always evident.

9
uDiastolic pressure can be detected by closely watching the dial of the manometer. If it
oscillates reproducibly at certain times on the deation cycle, this corresponds to within
10mm Hg of the diastolic pressure (by sound). For accuracy, when the diastolic sound cannot
be heard, pressure is simply recorded as “systolic all the way down”. This is especially
frequent during periods of high stress when the vessels are under signicant catecholamine
inuence and the area is acting “sti”, or in very small or cold patients where the vessels are
simple to small to allow sound change detection.
Note:Normalsystolicvaluesofdogsandcatsrangefrom110-160mmHg.
CLEANING INSTRUCTIONS
WARRANTY
Probe

CAUTIONS
PACKAGE CONTENTS
Probe
uThe standard probe is for transcutaneous use ONLY. The probe transducer is a very thin and
delicate part. Please take care NOT to drop or hit the probe tip. DO NOT submerge probe in
any liquid.
UltrasoundGel
uALWAYS use an ultrasound gel. Using other materials such as baby oil or cream may not
produce the correct Doppler sounds and may damage the probe.
Battery
uWhen battery is low, the power indicator becomes dark. Also there will be no speaker sounds.
Replace the battery if these conditions exist (refer to Figure G on page 7).

The JorVet Doppler is designed to receive blood ow velocity information by ultrasound. A
specic frequency is transmitted from the probe to the patient.
Technically, the transceiver amplies a high frequency oscillation output for transmission to the
transducer. The voltage is converted by a piezoelectric crystal (transducer) to ultrasound. The
ultrasound beam is transmitted to blood cells owing through the arteries or to beating fetal
hearts. The ultrasound beam is reected by the crystal in the transducer which converts the
ultrasound into a voltage. A Doppler shift occurs between the emission and reception of the
ultrasound beam.
Advantages of using Doppler ow detectors include ease of application, portability, applicability
to hypotensive animals, and usefulness as an audible monitor of the arterial pulse and peripheral
blood ow.
