5. Blood Pressure Measurement
5.1 Cuff Sizing
The SunTech Vet30E comes with a variety of different BP cuff sizes. Each cuff contains important markings that help
with selecting the right cuff size. These are SunTech designed symbols.
Make sure this part of cuff is placed over the patient’s artery.
When the cuff is
wrapped around the patient’s limb
or base of the tail, its Index Marker should fall
within this line.
When you wrap the cuff around the patient’s limb
or base of the tail, the Index Marker should fall within
the Range Marker on the inside of the cuff.
Indicates limb/tail circumference range of the cuff.
Not made with natural rubber latex.
Not made with PVC.
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 circumference for dogs and 30% for cats.
5.2 Applying the Cuff and Taking a BP Measurement on Small Animals
WARNING:
The cuff should not be applied over a wound as this can cause further injury.
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.
1. Position patient so that they are lying down, seated, or held. Place the cuff on the limb making sure not to place it
over a joint. Connect cuff hose to monitor hose.
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.
