OzVader V1

Product Specifications and Capabilities

Our ventilator. Reliable and Flexible.

Designed by a collaboration of Australian engineers and specialist medical professionals, the OzVader has been developed specifically to treat the global COVID-19 pandemic.
Our medical team includes some of Australia’s leading intensive care specialists, anaesthetists and respiratory doctors. These doctors represent leading Australian hospitals including The Prince Charles Hospital in Brisbane; and Austin Hospital and Epworth Hospitals in Melbourne.
Critical COVID-19 patients experience severe breathing difficulties however lung function is generally compliant. For this reason, higher order ventilation modes such as synchronised intermittent mandatory ventilation (SIMV) etc, are not generally required.


Designed for reliability and flexibility to suit all possible working environments from Tier 1 ICU wards to field hospitals & ambulances. Importantly comprised of readily available materials and parts which are resilient to deteriorating supply chain conditions and ventilator parts shortages.

The OzVader has a sophisticated alarming system which can be viewed here


Our Design Philosophy. Our point of difference.

Patient safety is paramount – the OzVader ventilator maintains precise control over delivered gas pressure via a suite of sensors and computer-controlled valves.
Leverages the ubiquitous Bag-Valve-Mask (BVM) that is commonly found in all hospitals around the globe.
It is agnostic to BVM supplier – the unique OzVader pressure housing is can handle the variances in BVM bag shapes and sizes.

The OzVader design allows for safe ventilation in a sedated +/- paralysed patient.

Several risk mitigation strategies have been put in place:

1.Mitigating ventilator induced lung injury
▪  Ability to perform an inspiratory pause manoeuvre enables clinicians to set safe tidal volumes and PEEP while targeting plateau pressures < 30 CmH2O and driving pressure < 15 Cm H2O.
▪ This is very important to reduce mechanical power delivered to the lungs.

2.Mitigating high inflation pressures and barotrauma
▪ A peak pressure cut off at 35cm H2O will limit inflation pressures and any risks of barotrauma
▪ Clinicians will be able to override the 35cm H2O PIP cut off while performing procedures such as bronchoscopy.
▪ This is important to ensure tidal volume delivery in situations where procedures such as bronchoscopy increase PIP.

3. Ability to set I:E ratios
▪ This will enable clinicians to adjust gas flow rates according to patients changing lung compliance, pulmonary gas exchange status and in situations where there is increased resistance from small airways (e.g. bronchospasm)

▪ HME filters can be safely placed in the circuit without increasing dead space or resistance.

5. Separate inspiratory and expiratory limbs
▪ This will minimise any risks of CO2 rebreathing and hypercapnia.
▪ Although devices that use one limb for both inspiration and expiration are acceptable in patients with near normal lungs, they may cause significant hypercapnia in patients with severely compromised lung compliance


The OzVader TGA accreditation process.

The Therapeutic Goods Administration (TGA) is the regulatory body for medical goods in Australia. It is a division of the Australian Department of Health.

The OzVader ventilator complies with all key requirements of the TGA COVID-19 ventilator specification.

The OzVader engineers are working with our medical team at the Prince Charles Hospital Medical Engineering Research Facility (MERF) in Brisbane. The medical performance data being collected will substantiate our accreditation submission to the TGA.

The OzVader ventilator complies with all minimum technical requirements for invasive ventilators listed in the Australian TGA specification: Ventilator for COVID-19 use in Australia” Revision 1.0, 05APR2020. 

OzVader’s submission to the Australian TGA is currently in review and the written permission for emergency exemption related to COVID-19 is pending.
