Product Description
Up for sale is a Veterinary Anesthesia Ventilator manufactured by Hallowell. Item is in used condition has been tested and does power on. No further testing done. Item is in excellent condition cosmetically. Includes only what is pictured. Power cord included.
OVERVIEW
The Hallowell 2002 Pro is an electronically controlled, time-cycled, pressure-limited ventilator. A single fine volume control valve turns a total of nine and a half times. The first two and a half turns use the slight, minute changes for pediatric animal patients, and the remainder of the rotations are for use with the adult and extra-large bellows and housings.Â
A low supply gas pressure alarm will sound when the supply gas pressure falls below 35 psi, 2.4 bar and stops around 42 psi. The normal supply gas operating pressure is 50 psi or 3.5 bar. It is not until 35 psi or 2.4 bar that the ventilators delivered volume will begin to drop off proportionally with the waning supply pressure.
Features
Electronic control – Eliminates the substantial driving gas required to operate pneumatically controlled ventilators.Â
Time cycled – Ensures 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 2/3 of the breath will remain for expiration. The respiratory rate is adjustable from 6 to 40 breaths per minute (BPM).
Volume constant – Ensures that each delivered breath will have essentially the same volume, independent of changes in animal patient compliance and airway resistance. The deliverable tidal volume (TV) range is from approximately 20 cc to 3,000 cc.
Pressure limited – Provides for animal patient safety by limiting the maximum working pressure limit (MWPL) to a user adjustable pressure range of 10 - 60 cm H2O. 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.
Adjustable I:E ratio – The adjustable range is from 1:1.5 to 1:4. The pros and cons are that this option affords the operator more flexibility in dealing with animals that have compromised lung function. But during anesthesia most animal patients are lung healthy and the addition of this control can add to the complexity of setting the ventilator. For example, consider that you have a hypocapnic animal patient. To bring that animal patients’ CO2 level to a more normal range, you must decrease the overall gas exchange, the Minute Volume (MV). Without this option, only one knob controls the MV, that is the volume control. With this option; however, increasing the I:E ratio would also cause a reduction in MV.
