The metacarpus, metatarsus and anterior tibial are recommended for the cuff placement. For
anesthetized patients, most surgeries are done on the posterior part of the body so the
metacarpal area of the forelimb is most convenient. In situations where this is not possible,
place the cuff around the metatarsus just proximal to the tarsal pad or around the hind leg
next to the hock. For conscious patients, measurements from the coccygeal artery can be used
over the tail site.

For larger animals
It is preferable for a large animal, such as a horse and a cow, to be in a stock, standing still.
Measurments from the coccygeal artery on the ventral surface may be used by placing the
cuff around the base of the tail.
NOTE
•
The limb chosen for taking the measurement should be placed at the same level
as the patient's heart
•
If the animal’s hair over the artery site is too thick or matted for good contact, it
should be clipped.
WARNING
•
The width of the cuff should be either 40% of the limb circumference or 2/3 of
the upper arm length. The inflatable part of the cuff should be long enough to
circle 50-80% of the limb. The wrong size cuff can cause erroneous readings. If
the cuff size is in question, use a larger cuff.
•
Do not apply the cuff to a limb that has an intravenous infusion or catheter in
place. This could cause tissue damage around the catheter when infusion is
slowed or blocked during cuff inflation.
•
Make sure the air tubing connecting the blood pressure monitor is not blocked,
twisted, or tangled.
