Safety Considerations
Intended Use
The SunTech Vet20 is intended to be used on companion animals, specifically dogs and cats, to obtain oscillometric
blood pressure measurements, including systolic, diastolic and mean arterial pressure and heart beats per minute. This
non-invasive monitor uses algorithms specifically designed for these animal populations.
User Responsibility
The SunTech Vet20 is designed to perform in conformity with the description thereof contained in this operation manual
when operated. The user of this monitor shall have the sole responsibility for any malfunction which results from im-
proper use, faulty maintenance, improper repair, damage or alteration by anyone other than SunTech Medical or their
authorized service personnel.

Warnings and
Precautions
1.
A WARNING indicates a situation which, if not avoided, could result in serious injury or death.
WARNING: DO NOT connect patient hose or monitor to any other devices or connections, especially
intravenous (IV) tubes as there is potential for air to be pumped into a blood vessel which could cause serious
injury.
WARNING: Do not use in the presence of flammable anesthetics; this could cause an explosion. This device is
not suitable for use in an oxygen enriched environment.
A CAUTION indicates a potentially hazardous situation which, if not avoided, may result in minor or
moderate injury to the user, patient or damage to the equipment or other property.
CAUTION: This monitor is for veterinary use only. NOT for use on humans.
CAUTION: DO NOT use the monitor for any purpose other than specified in this manual without written
consent and approval from SunTech Medical. Substitution of a component or accessory different from that
supplied may result in measurement error. Repairs should be undertaken only by personnel trained or
authorized by SunTech Medical.
CAUTION: DO NOT use this monitor when oscillometric pulses may be altered by other devices or techniques.

2
CAUTION: DO NOT immerse the monitor in any fluid, place fluids on top of or attempt to clean with liquid
detergents or cleaning agents. This may cause an electrical hazard. Do not use the monitor if accidental
wetting occurs.
CAUTION: DO NOT remove unit covers. Doing so may increase the risk of electrical shock. This monitor does
not contain any user serviceable parts.
CAUTION: DO NOT gas sterilize or autoclave this monitor.
CAUTION: Too frequent measurements may cause injury to the patient due to blood flow interference.
CAUTION: At the end of product life, the monitor, accessories, and other consumable goods may become
contaminated from normal use. Consult local codes and ordinances for proper disposal of equipment and other
consumable goods.
CAUTION: The monitor may not operate correctly if used or stored outside the relevant temperature or
humidity ranges described in the Performance Specifications.
CAUTION: Do not use if device is dropped and/or is damaged. Have a qualified service representative check
the unit before using again. Repairs should only be conducted by an authorized SunTech Medical service
representative.
CAUTION: Remove batteries when device is not in use for long periods of time to prevent possible battery
leakage and product damage.

A TIP provides application tips or other useful information to assure that you get the most from your
equipment.
TIP: This device is designed to be used on dogs and cats. In this document where the word “patient” is used, this is to
mean a small animal such as a cat, dog, or other small animal.
TIP: Accuracy of any blood pressure measurement may be affected by the position of the subject, the patient’s physical
condition and use outside of the operating instructions detailed in this manual. Interpretation of blood pressure
measurements should be made only by a veterinarian or trained medical staff. Minimize limb movement
during the measurement.
TIP: To obtain accurate blood pressure readings, the cuff must be the correct size, and also be correctly fitted to the
patient. Incorrect size or incorrect fitting may result in incorrect readings.
TIP: ENSURE batteries are inserted with the correct polarity. Improper installation may cause equipment damage or
malfunction. Follow battery installation procedures.

Animal Selection Screen
When you turn on your SunTech Vet20, you will see the Animal Selection Screen. Even if you are not ready to measure BP on
a patient, select either Large or Small animal so that you can proceed to the Main Screen. This screen can be turned off (see
Animal Selection). Additionally, the animal mode can be toggled using the animal selection icon on the Main screen.
Choosing the Correct Companion Animal Mode
Small Animal Mode should be chosen when taking BP measurements on all cats and small dogs up to a #3 BP cuff size. Large
Animal Mode has been designed for dogs requiring a #4 BP cuff or larger. This size typically applies to dogs weighing more than
8 kg (~17.5 lbs.). If a problem arises try switching animal modes.

but no beeps.

Clinical Alarms
The SunTech Vet20 allows clinical alarms for all BP values (SYS, DIA, MAP and HR). Factory setting is OFF.
• To change alarm values, touch Set Alarm Values.
• Touch the range value that you want to adjust.
• Using the keypad, type in the desired value and touch the checkmark.
• To reset to default clinical alarms, touch Use Defaults.
• Out of range values will be Red on the Main Screen. If speaker is ON,
a beep will occur.

Power Management
The SunTech Vet20 includes an auto OFF feature which turns
the monitor off after a selected time period.
Factory setting is 1 minute.
• Intervals include 1, 2 and 5 minutes as well as always
ON.
TIP: Batteries may be rapidly depleted if set to always ON.
Animal Selection
The animal selection start up screen can be turned OFF. This
is useful for clinics catering to a specific breed such as an all
cat clinic.

These preparations can help ensure a successful and accurate blood pressure measurement.
Where to Apply the Cuff
SunTech recommends that the cuff be placed on a front limb while the patient is lying on the right or left side. This helps
ensure that the cuff is at heart level, which is best for measurement accuracy. Also, the patient is less likely to retract the front
limb when the cuff gently squeezes it during the measurement. The cuff should be placed so that its artery marker aligns with
the limb artery.
Alternate Patient Positioning: If the patient seems more comfortable seated, position the cuff as described above and hold up
the limb during the BP measurement. This will help keep the cuff at heart level and relax the patient’s muscles. If the patient
appears agitated enough to bite or scratch, or is standing, the base of the tail is an acceptable alternate location.
Cuff Size
The SunTech Vet20 comes with a variety of different BP cuff sizes. Each cuff contains important markings that help with
selecting the right cuff size.
Before You Begin:
Important Preparations
5.

13
Make sure this part of cuff is placed over the patient’s artery.
When the cuff is wrapped around the patient’s limb, its Index Marker should fall within this line.
When you wrap the cuff around the patient’s limb, the Index Marker should fall within the Range Marker
on the inside of the cuff.
Indicates limb circumference range of the cuff.
Not made with natural latex.
TIP: When more than one cuff size fits the limb, always choose the larger size for more accurate measurements. When a cuff
is too small, it can cause BP values to be overestimated.
An alternative sizing method is to measure the circumference of the limb and choose a cuff whose width is 40% of the cir-
cumference for dogs and 30% for cats.

14
Taking a BP Measurement
Step 1. Place blood pressure cuff on patient and connect hoses.
Position patient so that they are lying down. Place the cuff just above the paw making sure not to place it over a joint. Con-
nect cuff hose to monitor hose. (See “Before You Begin” for cuff size/placement guidelines and alternate positioning options.)
TIP: The success of the BP measurement is dependent on choosing the correct cuff and attaching it to the patient correctly.
The cuff is the sensor so make sure to snugly fit the cuff as this provides better signals to the monitor.
Step 2. Power up and select animal mode.
Press the Power Button. Select Large or Small companion animal.
TIP: To change animal size after initial selection, touch the Animal Selection icon on Main Screen to toggle between Large
and Small.
Step 3. Take blood pressure reading.
Press START/STOP button to start blood pressure measurement. START/STOP button turns Blue during measurement. Reading
is complete when START/STOP button returns to Magenta. Main Screen will show SYS and DIA values, plus MAP and heart
rate (BPM).
Interrupting/Stopping a Measurement
To stop a measurement while in progress, touch the START/STOP button. START/STOP button returns to Magenta and moni-
tor is ready to start new reading.
