Power ON the petMAP+II. Press and release the ON/OFF button on the right side of the unit to
power the device ON. The same button is used to power the device OFF.
Measuring Blood Pressure
petMAP+II can operate in either “Clinic Mode”, where blood pressure measurement frequency is under
user control, or in “OR Mode”, where measurement frequency is determined by the user by setting the
BP cycle time for automatically repeated BP measurements at the set cycle time.
Cuff placement. In either mode, the first step for accurate determinations is to select the proper sized
cuff and to apply it, snug tight, to the best limb available. The available cuff sites include the forearm,
tail or hind foot. To achieve the most accurate and consistent readings, it is recommended that the
forearm or base of the tail be used on cats (either works well). For dogs, the base of the tail if the
preferred site, followed by the forearm. The hind foot is the least accurate and should only be used if
the forearm and/or tail cannot be used. Generally, there is no need to shave or clip the hair or fur;
however, it is critical to apply the cuff snug tight. In the case of BP measurements on long haired
animals, wetting the fur to allow better compression by the cuff may be beneficial in terms of ease of
cuff placement and potentially better accuracy.
For species other than cats and dogs, follow the BP basics with respect to cuff sizing and placement: 1)
place the cuff as close to heart level as possible, since there is an offset of +/- 2 mmHg for every inch of
vertical difference between the heart and the cuff, 2) use the correct sized cuff, and 3) there should be
no pressure on, nor any movement of, the limb or the animal during a BP measurement.
BP extension hoses: petMAP+II is supplied with two BP extension hoses, which can be used to increase
the distance between the petMAP+II and the cuff. The extension hoses are approximately four feet
long and come in two different sizes. One size is used with the smaller cuffs (2.0 – 5.5cm) and has a
smaller diameter which is the same size as the smaller cuff hoses; the other extension hose is used with
larger cuffs (6.5 – 13.0cm) and has a larger diameter as do the larger cuffs. It is extremely important
that the proper extension be paired with the cuff being used. However, in exceptional cases of very
difficult patient positioning, it may be necessary to join the two different diameter extensions together
to reach a remotely placed patient, but degradation in accuracy and performance should be expected if
this is done.
petMAP settings: Using the Species Cuff Site button at the bottom of the screen, press and release to
set the species and cuff site appropriate for the patient being measured. There are three settings for
dogs (forearm, hind foot and tail) and the same three for cats. The settings are displayed at the top
center. Using these settings, which are referred to as “optimizations”, will improve the correlation of
the reading results to intra-arterial pressures based on petMAP’s unique algorithms. If the species being
measured is not a dog or a cat, the seventh setting, the “non-optimized mode”, should be used. The
non-optimized setting should also be selected if attempting to compare readings from other BP devices
to the petMAP.
