One ventilator for all your small animal practice needs, from small rodents to large dogs.

The Vetronic Merlin veterinary ventilator has been designed with just that in mind. Using the latest technology, Merlin is able to precisely control ventilation parameters to ensure your patient is as safe as can be during mechanical ventilation. Merlin doesn’t require a compressed gas supply to operate, so is quiet and smooth. And, because Merlin is controlled by a state-of-the-art microcontroller, you can confidently set the independent ventilation parameters that you want, without compromise.

Merlin is a microprocessor-controlled ventilator, designed by vets for vets. We have done away with the conventional pressurised gas driving mechanism. This new ventilator uses a precisely-controlled piston that can accurately delivery volumes in the range 1ml to 800ml.

Merlin can be pressure cycled, volume cycled or time cycled and the inspiratory and expiratory times are fully and independently variable, without the need to re-adjust after changes in flow rates or volumes. A pressure control allows you to set the maximum allowable pressure during volume cycling, or the target pressure during pressure cycling.

A further added feature is the inspiratory assist control that will tune the ventilator to your patient during recovery and so assist weaning from the ventilator. On the front of the unit is a large, easily-readable display that shows all of your selected parameters. The parameters are continuously updated, reflecting every adjustment made.

In addition, we believe Merlin is truly innovative in being the first veterinary ventilator to calculate and display the compliance of the patient being ventilated.

The MRI Viable Merlin Ventilator has been adapted to be compatible with much longer tubing, allowing the ventilator to be further away from the patient and out of the MRI zone.

The Merlin comes supplied with everything you need to use the unit out of the box, including:

Merlin FAQ's

Q. What patient range does Merlin Support?
A. 150g to 80kg

Q. What modes does Merlin support?
A. Merlin supports volume cycle, pressure cycle, and time cycle modes.

Q. What happens if there is a power cut?
A. All valves will fail open. The Patient can then breathe spontaneously on the ventilator in the normal way.

Q. What is the maximum and minimum flow rates that Merlin can deliver?
A. Max 25.0L per min, Min 0.1L per min.

Q. Does Merlin have alarms?
A. Yes. The Merlin will alarm because:
1) Inspiratory pressure not reached (volume cycling)
2) Max pressure exceeded (volume cycling)
3) Target pressure not reached (pressure cycling)
4) Gas inlet blocked (all modes)

Q. How do I clean or disinfect Merlin?
A. Follow the ‘Merlin Cleaning Procedure’ document found in the attachments on this page. There is also a video showing this procedure.

Q. How do I test the Merlin for leaks?
A. Follow the ‘Merlin Leak Test’ document found in the attachments on this page. There is also a video showing this procedure.

Q. Can I use the Merlin on a Circle System?
A. Yes. Merlin can be used with rebreathing and non-rebreathing systems.

Q. Can I use Merlin without an anaesthetic machine?
A. Yes. Merlin can take any gas into the chamber, so Merlin can use room air taken into the gas port or any other introduced gas.

Q. Can Merlin be used with varying FiO2?
A. Merlin cannot change the FiO2 but the single intake port allows air to be easily enriched with oxygen or blended externally and fed into Merlin.
