Consistently smooth, predictable, and successful general anaesthetics  

Vanessa Persson, Observatory Animal Clinic, Cape Town

The Humphrey Free-Ox low – flow anaesthetic machine with a Sevofluorane vaporiser has definitely been my most worthwhile and rewarding purchase in my new practice. A year has now gone by with consistently smooth, predictable, and successful general anaesthetics in all our patients. This has been regardless of age or anaesthetic risk. The recovery times are fantastic and Dr Humphrey has proven to be an invaluable source of information whenever I have had any questions. I am a complete convert!!

Free-Ox and Mini-portable anaesthetic machines

Graeme Harman , Casterbridge Animal Hospital, White River, Mpumalanga.

I just wanted to write to you and congratulate you on your excellent anaesthetic machine. Casterbridge Animal Hospital has been running the Free-Ox Anaesthetic machine for the last 8 months without a single problem and I do feel this is testament to the superior quality of your system.
As you know we have now purchased your Mini Humphrey low-flow anaesthetic machine and both machines are working well together. I bought one oxygen cylinder as a backup in case of power failure. I’m happy to say that I still have never had to use it and have thus not had to pay a cent for Oxygen in the past 8 month. Being located in the Lowveld we have had a lot of snake bite patients in particular, which often need up to 12 hour non-stop oxygenation and your system is allowing us to give a very high standard of patient care in such cases in particular.

Endorsed not only by vets but also by medical anaesthetists

Kevin Hackett, Avalon Veterinary Hospital, Kirstenhof, Cape Town

I have been using Dr Humphrey’s anaesthetic system for over ten years and I have no hesitation in recommending it to fellow Vets. As you are probably aware Dr Humphrey is a medical anaesthetist who designed his circuit for mission stations and realised it could be used in a veterinary scenario. It is both efficient to use and simple in design to give excellent anaesthetics and to run very economically. He has developed a low flow system which can operate both on small patients or with the re-breathing system for larger dogs. This operates on extremely low flows for large dogs and this of course is an enormous financial saving both for the inhalant used and also for oxygen consumption. Dr Humphrey has revolutionised the veterinarians modus operandi by providing excellent anaesthesia which becomes a lot more economical and less risk for staff in theatre fcurredrom exposure to the gas .Initially I used the Isoflurane in my circuit which was very satisfactory but upgraded to Sevoflurane approximately five years ago. The reason for the change is that Sevoflurane is not only a more potent anaesthetic but also safer for reversal. It gives superb relaxation of abdominal muscles for surgery which allows easier wound closure and I believe less pain in recovery. It also provides a better recovery form the effects of anaesthetics and is the chosen anaesthetic in the human field where paediatrics endorsed it for babies and children some years ago. It was endorsed to me by Dr Jenny Thomas the head anaesthetist at Cape Town Red Cross Hospital and if anyone needs reassurance please speak to her (I am quite sure she would be delighted to discuss its merits ). As a profession we are indeed very fortunate to have Dr Humphrey as an educator and supplier of the best equipment which he personally will service on site (a very important part of using equipment).

It should be noted that the low flow system is particularly important for saving money and making it affordable to use. We are also fortunate that Sojourne (generic of Sevoflurane) is available to us in RSA at a fraction of the cost incurred in the UK. Dr Humphrey has had major effect in bringing the best equipment to us and he has not only spoken at International Conferences both here and also at the BSAVA in the UK where he has been very well received .Another veterinarian who is a leading anaesthetist is Dr Kenneth Joubert who would also vouch for Dr Humphrey’s credentials .The vaporiser for the Sevoflurane is the Rolls Royce in its field manufactured in the UK. It provides very accurate calibration which was illustrated to me a month or two ago.

Fantastic positive pressure ventilation

Nic Bangay, Seadoone Veterinary Clinic, Amanzimtoti

The machine is going really well. We have done procedures that we would never have even dreamt of doing before.We have anaesthetised a four-week old puppy to stitch a wound on its shoulder. It has already saved a life by allowing us ventilation and oxygenation! We have done a dental on a 19 year old cat, and a 13 year old cat. All in all, we are very happy and feel very upmarket and “posh” in our practise!

New Zealand Testimonials

Never going back to older breathing systems

Dr Mike Gething, Howick Veterrinary Clinic

Just a note to confirm for your interest that the two ADE systems we purchased from you are performing admirably. All four vets and the theatre staff have now adjusted to the changes in using your system. The benefits of reduced use of isoflurane, less wastage and pollution, and the ability to provide a low flow general anaesthetic that gives a smoother more effective result for the patient have appealed to all of us. No one would return to the old Bain or large circle system!!! We have implemented the advised maintenance procedures

Green – safety to patients and staff

Dr Peter McQueen, SPCA, Auckland

We have recently purchased three of your anaesthetic systems as replacements for the systems we were using. They are working well & producing the benefits which motivated us to purchase them. They are very sparing on both anaesthetic gas and oxygen which should give us financial savings of between 60-70%. With this reduction in anaesthetic consumption, there will of course be a reduction in atmospheric and theatre pollution, and therefore an increase in safety for our staff. Our patients will also benefit from the system’s design as it is very efficient, working with low gas flows and very little airflow resistance. As a clinic that anaesthetises hundreds of puppies & kittens every year, this is obviously important. Thanks again for introducing this innovative equipment that is certainly far superior to what we were using.

Advances in veterinary anaesthesia

Dr Richard Jerram – Veterinary Specialist Group, Auckland

Dr Humphrey has visited our veterinary hospital on several occasions over the past few years and his guidance has helped us make some considerable advances in the way in which we practice veterinary anaesthesia. The Humphrey ADE-circle system is extremely well designed and easy to use. I frequently recommend this product to other veterinarians.

Innovative and unique

Dr Scott Drummond, Green Island Vet Clinic DUNEDIN

His product is innovative and unique and introduced new technology to the marketplace … We have been pleased with the quality and dependability of David’s product and the follow up service we have received from him.

Technical expertise is invaluable

Dr Hans Anderson, Halifax Veterinary Centre. NELSON

Dr David Humphrey demonstrated his Humphrey ADE anaesthetic system about 18 months ago at our clinic. I was so impressed, I bought three on the spot, and helped arrange lectures and demonstrations. Not only is the equipment excellent, giving significant benefits in patient safety at lower operating cost, but also David’s technical expertise is invaluable. This is especially evident during his clinic visits as he advises on many aspects of anaesthetic equipment set­ ups, utilisation and safety.

Well designed, easy to use

Dr lan Schraa Paremata, Paremata Veterinary Hospital, WELLINGTON

… thank you for the sale and installation of your well-designed ADE anaesthetic systems (2 bought). They have delivered on all the fronts that you said they would… Also their simplicity has made them easy to use and easy to train new staff to use, such that we can have high confidence in our anaesthetic protocols.

A good example was last week when we performed a repair to a traumatic diaphragmatic hernia in a 2. 5kg cat. The simplicity of managing the manually controlled respiration during surgery with the unique pop-off valve system of the ADE-circuit made the whole procedure much easier. The cat has made an excellent recovery.

Economical compared to older breathing systems

Dr David Kettles, Central Hutt Veterinary Clinic, LOWER HUTT

We have been using the Humphrey ADE-Circle Anaesthetic System for about 6 months now and find it safe and simple to
use. We have found the system to be a very economical option in comparison with our previous Bain system. There are
significant cost savings on both isoflurane and oxygen usage.. We appreciate the technical support given both pre and
post purchase and the ease of servicing provide by Anaequip-vet NZ.

Low running costs

Dr Andea Wilson, Raumati Veterinary Centre, Raumati

As the machine runs on amazingly low oxygen flow rate, we have also found that our use of both anaesthetic agent and oxygen has been markedly reduced. This benefits us not only financially but we are pleased to think that there is less theatre and atmospheric contamination.

Revolutionised our anaesthesia

Dr Michael Lintott – Carlyle Veterinary Clinic, Napier

Thank you for supplying the two Humphrey ADE-circle anaesthetic systems we purchased in March 2006. They have revolutionised our anaesthesia with the practice and are in use daily. The systems was even used successfully on an orthopaedic procedure on a donkey recently!

Our staff have adapted to their use very quickly which is amazing when we have used the old systems for so long. I’m sure this is in part at least due to your clear and easily understood explanations of how they function, and their care and maintenance when you installed the units. There is no equivalent product on the market in New Zealand.

Saves costs by using less anaesthetic agent and oxygen

Dr Mark Simpson – Auckland Veterinary Services Glen Eden

We find the use of this system very beneficial as it saves costs by using less anaesthetic agent and oxygen…less pollution… it is safer for our patients as it automatically prevents pressure build up with the anaesthetic circuit.

Simple and highly efficient

Dr Roslyn Machon, Massey University Veterinary Teaching Hospital

I have used his Humphrey ADE Anaesthetic system found it a very useful patient breathing circuit in very small patients such as cats and dogs. The system is simple and highly efficient. The system appears to be of high quality and I have certainly found it useful.

So costeffective that the ADEs pay for themselves

Dr Don Alexander Pukekohe Vet Centre, Pukekohe

I calculated in our veterinary practice using costings from the previous year, that the total cost of the four (ADE) machines would have paid for themselves in savings on Isoflurane and oxygen in approximately 11 months. It made good common sense to have 4 systems all functioning the same …. In the 15 months that we have been using the system we have not
experienced any anaesthetic complications. I am very happy with the Humphrey ADE system and strongly recommend that all Veterinary Practices in New Zealand purchase one to see for themselves the huge benefit to the animals, Veterinary staff and the environment

Less pollution

Dr Mark Simpson Auckland Veterinary Services Glen Eden AUCKLAND

We find the use of this system very beneficial as it saves costs by using less anaesthetic agent and oxygen … less
pollution. .. It is safer for our patients as it automatically prevents pressure build up with the anaesthetic circuit
