The Hallowell EMC
Models 2002 and 2000 are electronically
controlled, time-cycled, pressure limited
ventilators.
Electronic control-- Eliminates the
substantial driving gas required to operate
pneumatically controlled ventilators.
Time cycled-- Insures consistently spaced
breaths. The possibility of stacking breaths
or auto-PEEP is eliminated by keeping the
I:E ratio constant at 1:2. This means that
regardless of the respiratory rate setting
two-thirds of each breath will remain for
expiration. The respiratory rate is
adjustable from 6 - 40 breaths per minute (BPM).
Volume constant -- Insures that each
delivered breath will have essentially the
same volume, independent of changes in
patient compliance and airway resistance.
The deliverable tidal volume (TV) range is
from approximately 20ml to 3,000ml using 3
interchangeable bellows and bellows housings
as seen here. Most small animal facilities
require only the small bellows attachment ,
seen at the left, with the standard size
ventilator, center.
Pressure Limited-- Provides for patient
safety by limiting the maximum working
pressure (MWPL) to a user adjustable
pressure range of 10 - 60 cm H2O.
The Model 2002, now our most popular
ventilator, was introduced in circa 2002
after numerous customer requests for a finer
volume adjustment at the low end of the
range. We added a finer volume control in
parallel with the existing control on the
Model 2000. Everything else about the Model
2002 is identical to the Model 2000.
Both ventilators are equipped with dual
airway pressure alarms that monitor and
sound when the peak inspiratory pressure
(PIP) of any breath either exceeds the
preset maximum working pressure limit (MWPL)or
fails to reach 6 cm H2O as in the case of a
disconnect.
A Low Supply Gas Alarm, available as an
option, would sound when the supply gas
pressure falls below 35 psi, 2.4bar. The
normal supply gas operating pressure is
50psi or 3.5bar. It is not until 35psi or
2.4bar that the ventilators delivered volume
will begin to drop off proportionally with
the warining supply pressure.
