Ventilator for veterinary ICU
Junior Member
I'm a veterinary critical care specialist looking to upgrade the ventilator at my new hospital. Believe it or not, they've been using an old Bennett MA-1 for the past few years!

Veterinary patients occassionally require mechanical ventilation for a variety of pulmonary diseases such as pneumonia, edema, contusions or CNS or neuromuscular disease resulting in hypoventilation. Our patients usually require only 2-5 days of ventilatory support until resolution of their disease. Long term ventilation is typically not an option because of the expense to the owner.

I've used the Newport Breeze at another facility but I'd like to get something with pressure support this time around. Unfortunately, equipment decisions often come down to money in the veterinary world. That usually limits us to older models, refurbished used, or retired demo models when it comes to ventilators. Most veterinary ICU's are currently using the Newport Breeze or the Siemens 300 or 900.

I've been considering the Siemens 300, Newport Wave E200, and the PB 760. I loved the Evita 2 but I think it's a little too much technology for this staff right now. Recently, the Pulmonetics LTV100 has found its way into the veterinary market. This ventilator has the advantage of graphics for the same price as the others. However, I'm having trouble finding information on the clinical use of the LTV1000 in human medicine. Is this used as an ICU ventilator?

I was hoping there was someone willing to share their experience with the LTV1000 and the other models I'm considering. Specifically, I am interested in how the LTV1000 handles a spontaneously breathing patient. I might be asking a lot since you probably haven't used these models in years!

Thank you so much for your input,

I work at Newport (we make the Breeze and Wave). If you are considering the LTV1000, I would encourage you to look at the Newport HT50. I can answer any questions you may have about the application of these products, since I am the one who carries the emergency pager and am familiar with several of the veterinary ICU facilities in the US.

I hope to hear from you soon.

All my best,

I cannot offer you any experience with ventilating animals but I would like to offer some thoughts. I imagine the size of the animal would require different ventilation techniques. A ventilator for a human patients must offer different flow characteristics depending on the patient size. The LTV 1000 seems to do well with children but may not keep up with a demanding adult. You should see the same experience with small and large animals. This flow issue is true of turbine based ventilators. The MA 1 is a bellows ventilator and cannot deliver more than 50 lpm when a patient is connected to it. So, if you never had that issue with you patients then the LTV may be ok. The LTV is in high demand in the market for home ventilator peds patients so the cost may be high. A Servo 900C is a great ventilator that can adjust flow with working pressure. The maintenance cost is high but you may be able to lower your costs by using longer intervals. If you are looking for a 900C, you can find them inexpensively and they are easy to repair. I do not know if the parts are available. I used to represent these vents and the only difficult thing to fix was the bellows. A Servo 300 is easier to maintain and more flexable but more expensive. The Newport Wave is a nice ventilator with lower operating costs and a lot of flexibility. I would feel comfortable with a used product from any of these companies. The Servo 300 and the Wave are PSols and probably offer the best operation. The 900C will cost less but may be more interactive to maintain. I would be concerned with flexibility of flow with Turbine vents. I am not familar with the new Newport. I have worked for a couple of different vent. companies and do not work for one now and would be happy to offer any advice. You can email me at if you have any questions about capabilities or value of various vents.

All the best,

The univ of Penn Veterinary School just bought the Respironics Esprit ventilator. Easy to use, great graphics and quite capable.

In our PICU, once a child is past thier acute stage and waiting for placement (or to go home)we put them on LTV's. We have one LTV 1000. They work nicely. The 1000 allows you the option to deliver smaller VT's than the 900 (in PCV). You won't be able to come close to it's price with the Espirit (12-15k for the 1000/ low 20ks for the espirit). Both have turbines. I'm sure you wouldn't have the flow issues that we would see in our ICU's, I'm assuming most of your patients are recovering from surgery and are uncomplicated. What area are you from? I wonder if their REP would let you trail a vent. If might result in a purchase, I don't see why noy. Hope this helps

Do you work with dogs and cats, or treat horses, ..or gorillas at the zoo? This may impact the ventilator you decide to use.

I took a 600 lb man on a transport one with the LTV. It worked great. The visual was like a take off on "The Little Train That Could" ("I think I can, I think I can).

I haven't worked with the Newport vents so can't compare. But I assume size of the vent in the room is an issue, so the LTV would come up good in that situation. You could even perhaps find an O2 concentrator and the LTV will let you bleed in the O2.

But I'd also check out the eVent

Good luck

I'd go for a vent that did not require any disposable flow sensors. The 900C is a nightmare to set up for the unexperienced, and the 300 may be way too much vent. If MA-1's have been doing the job, a PB740 or an Espirit would probably be a nice fit, and both are inexpensive.

Then again, I bet you can grab an eVent for next to nothing as well. Just be sure thye give you a load of flow sensors!

The Servo-I can set tidal volumes between 2cc and 4000cc's. You should be able to ventilate any animal with that range.
