Well, it's been 15 years since I made the initial sketches for a large animal ventilator. Now after 3 years of steady, serious work on the project in collaboration with Keith Simpson and Vetronic Services of the UK, Tafonius is finally ready for the market. You will find this machine like no other for ease of use, ease of cleaning, accuracy, strength and economy. Tafonius sports features such as : PEEP and CPAP delivery, integrated monitoring, data collection and much much more.
