Introducing the Tafonius, the only piston driven large animal ventilator on the market.

Designed for the demanding veterinary environment, the Tafonius has no need for a driving gas supply and has an uninterruptable power supply that means it can continue running for up to six hours in the event of a power failure – that is all your monitoring and ventilation with no interruptions.

Controlled via a large 15” touch-screen computer, the ventilator is easy to set up and control. There is reporting feedback on ventilation parameters, as well as fully configurable patient monitoring, giving you more control. Set up which parameters you would like to show, where you would like to see them and even set the colour that you are used to working with. These configurations can be saved per user, so you can simply switch on the machine, choose a saved configuration, and get started. Patient data is recorded and stored for later retrieval and analysis.

Additional features include PEEP, where the ventilator applies a pressure at the end of each breath to ensure that the alveoli are not prone to collapse, improving oxygenation. CPAP – continuous, positive airway pressure to overcome hypoxaemia, the insufficient oxygenation of arterial blood. Assist mode – helping get oxygen into a patient that is not taking in regular breaths and a buffer volume controller.

What makes the Tafonius different from any other ventilator?

Tafonius does not use any pressurised gas to drive the ventilator. Instead a precision motor system controls piston movement. This results in silent operation, reduced running costs and precise control. The advanced motor system and motor control means that the piston can behave like a virtual bag during spontaneous ventilation and during the expiratory phase of controlled ventilation.

It also means that any part of the respiratory cycle can be executed as a series of phases of varying lengths. Any phase can have a resolution of less than 1/100th second. During normal IPPV for example, only one phase is used during inspiration and this lasts the full length of inspiration. During expiration multiple phases are used each one lasting 5ms (200 times per second). In each of these phases the airway pressure is measured and the piston moved accordingly. Not only does this system provide very smooth control of breathing but allows the implementation of an Airway Servo System to control patient airway pressure.

Airway Servo Pressure

If the Servo Airway pressure is set to 0 cm H₂O then the patient experiences no resistance to breathing out, significantly reducing the work of breathing. To the patient it feels like exhaling to ambient with no machine attached. If the Servo Airway pressure is set to 5cm H₂O then the patient experiences 5cm of CPAP or PEEP. With the combination of multiple phases and an Airway Servo System, any pattern of breathing can be designed and implemented. In time, researchers will develop a library of ventilating modes, patterns, sequences and manoeuvres that can be used to ventilate your patient. No longer will you need to buy a machine to obtain new features.
