OPERATING INSTRUCTIONS

• 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
• Connect the probe with the small dot up on the probe connector (12 o’clock). See Figure B
•  Depress the probe button to turn the unit ON. See Figure C
• 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
• Connect the headset when necessary. Headset can be used to listen to Doppler sounds.
• It will cut off the MiniDop speaker to the room. See Figure E
•  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
• 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

1.  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.
2.  Place a large “dollop” of ultrasound gel on the non-numbered side of the Doppler flow probe. Place the probe in the location of the artery described in above and tap it in place tightly.
3. Ensure that the unit is charged. A swishing sound should be heard each time blood flows through the artery. If blood flow 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.
4.  Make a loop in the cord of the flow probe. Tape the cord to the foot/metacarpal loop right over the tape used to fixate the flow probe to the skin initially.
5.  The blood pressure cuff is now in place. The cuff’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 cuff is directly over the posterior medial aspect. 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 flow is now temporarily blocked.

CLEANING INSTRUCTIONS

PRINCIPLES OF DOPPLER FLOW

The JorVet Doppler is designed to receive blood flow velocity information by ultrasound. A specific frequency is transmitted from the probe to the patient. Technically, the transceiver amplifies 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 flowing through the arteries or to beating fetal hearts. The ultrasound beam is reflected 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 flow detectors include ease of application, portability, applicability to hypotensive animals, and usefulness as an audible monitor of the arterial pulse and peripheral blood flow.
