measured with indirect devices and, as previously mentioned,
most of these devices (Doppler and oscillometric)
underestimate the intra-arterial systolic pressure by 10-20%.
The study of hypertension and its treatment is an evolving
subject in veterinary medicine. It is suggested that
veterinarians refer to the literature, including the ACVIM
Consensus Statements, published on this topic.
Battery Considerations
In order to maximize battery life, petMAP is designed to turn
the display completely OFF following a determination when the
unit is motionless for more than 12 seconds. If the unit is not
re-pressurized for a new determination within 10 minutes,
petMAP will turn OFF. Battery life for petMAP will vary
depending upon the type of batteries used and the number of
determinations made.
Three types of AAA batteries may be used to power the
petMAP:
1) disposable alkaline batteries (Energizer Alkaline and
DuraCell Coppertop, for example)
2) rechargeable NiMH (nickel metal hydride) batteries (850 –
1000 mAh)
3) disposable lithium batteries.
Disposable zinc-carbon (Heavy Duty/ General
Purpose) batteries and NICAD batteries are not
recommended.
Fresh alkaline batteries and fully charged NiMH batteries yield
approximately equal battery lives; however, NiMH batteries are
rechargeable and may be reused many times, making them
the most affordable long-term option. Lithium batteries yield
almost twice the life of alkaline batteries, but are approximately
twice as expensive. Zinc-carbon batteries yield approximately
one-third the life of alkaline batteries and, therefore, are not
recommended for petMAP.
The LoBat (red LED) signal is activated well before the
batteries are completely depleted. Up to one hour of
continuous usage may remain on alkaline batteries once the
