The SAV04 is an enhanced version of the long-standing SAV03 ventilator and uses the same principles of simple, pressure-cycled ventilation.
In the redevelopment of the ventilator, features have been added to improve patient control and to improve ventilation status feedback. For example, there is now an automatic over-pressure alarm that will sound if the target pressure is exceeded by 8cm. There is also an alarm if the patient becomes disconnected from the ventilator, or if no back-pressure is detected during the inspiratory phase.
These alarms are designed to be informative and are accompanied by explanatory text on the main screen. In addition, an audible beep is produced on every successful breath. Both this beep and the alarm beeps can be individually silenced if required. There is a new valve design to accompany the new ventilator and this has two major benefits.
Firstly, the valve can be automatically zeroed on any other SAV04 machine allowing valves to be swapped or replaced easily.
Secondly, a larger orifice in the exit port of the valve means the port can now support larger animals. The 12mm diameter exit orifice will now allow unrestricted expiration in animals up to 40kg.
It must be remembered the principle of operation is still based around a T-piece, so proportionately higher fresh gas flow rates will be required. However, with the advent of oxygen generators, running such a system on 8-10L is feasible for short-term or emergency use. The new display now provides more information to the user. A central rising bar graph shows the pressure in the patient’s airway, enabling quick assessments to be made on system and/or ET tube leaks. Each inspiratory period is now measured and displayed on the screen as is the measured respiratory rate.
The SAV04 provides a simple, yet safe, way to ventilate your smaller, most vulnerable patients. T
