OXERA OXYGEN DEVICE

OxERA is a simple, efficient, portable and cost-effective device that delivers consistently high levels of oxygen to COVID-19 patients.

The device’s key components are an anaesthetic mask and an adjustable mechanical valve, known as a positive end respiratory pressure (PEEP) valve. Oxygen supply is via a hose and accumulator bag, with the hose connected to any available oxygen source.

Key Benefits of OxERA

Clinically effective

Able to provide superior levels of care compared to standard non-rebreather oxygen masks.

Low oxygen consumption

Up to 15l/min required, as it can operate at any oxygen flow rate by entraining extra room air, as required, through the anti-asphyxiation valve. This is no more than the standard oxygen masks already being used. Can be used on any oxygen source from oxygen concentrators to bottled and piped ward oxygen.

Efficient oxygen consumption

Through the snug fitting mask and accumulator bag, all the oxygen flowing down the line is available to the patient rather than being wasted when the patient exhales.

Cost effective

All levels of hospital staff and GPs quickly become familiar with using the device, meaning it can be used anywhere.

Simple to use

Locally designed and manufactured with off-the-shelf items used where possible.

Safe to use

Equipped with an anti-asphyxiation safety device in case oxygen supply runs out or is disconnected. Expired air filtered to keep environment safe for health care workers. Fully SAHPRA approved for Covid-19 emergency use.

Portable

Can be used anywhere where a suitable oxygen source is available ranging from home and ambulances to tertiary hospital level.

The challenge

South Africa, like many developing countries, finds itself burdened with a high Covid-19 patient load but with a lack of skilled staff, ICU and high care facilities and bulk oxygen supplies to be able to effectively manage patients.

Gabler Medical hold the necessary Emergency Covid-19 SAHPRA approvals for manufacture, sales and distribution (local and international) of the OxERA™ device.

OxERA™ bridges the gap between the two resource environments and extends the care available at small hospitals and clinics.

The innovative OxERA™ is an all-in-one device using an anaesthetic mask and an adjustable mechanical PEEP valve that is simple, cost effective and oxygen efficient. Tests have shown that not only can consistently high levels of oxygen be delivered with the critical benefit of PEEP, but less oxygen is usually needed as the flow rate can be adjusted to the patient’s demand rather than having to be left fully open to compensate for leaks, as in an open system.

In our oxygen resource constrained environment, this is a game changer. This allows even the most basic facilities that are dependent on bottled oxygen or small oxygen concentrators to provide a higher level of clinical care than they are currently able to. It also means that the device is suitable for use in transferring patients in ambulances where other options are limited.

*Positive End Expiration Pressure (PEEP) and Positive Expiration Pressure (PEP) assist with oxygenation by preventing atelectasis (collapse) of the small air sacs called alveoli in the lungs.

How does OxERA work?

The OxERA™ device assists patients by providing high percentage oxygen plus maintaining slight pressure, to keep their lungs from collapsing during expiration, via an adjustable PEEP* valve. This reduction in atelectasis improves oxygenation, decreases trauma to the alveoli and reduces the work required to re-open the alveoli and hence the work of breathing.

It comprises a custom designed main housing, incorporating an adjustable PEEP valve (5 – 15 cm H2O), anti-asphyxiation valve (for safety) and oxygen supply via tubing and accumulator bag. The oxygen tubing can be connected to any available source of oxygen.

Commercial medical devices such as an anaesthetic mask and viral filter complete the package together with simple but effective elastic head straps.

Key to the device’s efficient use of oxygen is the fact that incoming oxygen is accumulated in the bag during expiration and is, therefore, available during inspiration together with the flow in the line.

In loose fitting masks and especially nasal prongs, high flow nasal canulae and even CPAP units, the lack of any accumulation of oxygen in a sealed system means that large percentages (up to 66%) of the feed oxygen are simply wasted – making them very oxygen inefficient. Under our Covid-19 conditions, with so many patients requiring oxygen at the same time, this is a major problem.
