Gasporox has formed a subsidiary - GPX medical. GPX medical will develop diagnostics devices based on Gasporox technology.

With Gasporox patented laser technology it is possible to measure free gas located inside the human body. Information about the gas inside the body can be used as medical diagnosis support of sinusitis, otitis and monitor of lung function of premature born babies.


Results of the SINUSLIGHT project have reinforced that there is a very clear need for the GPX Medical device in terms of global health. Dr Bergsten sums up the massive implications brought about by the SINUSLIGHT review: “We see a great business potential in both applications, sinuses and lungs, and are now starting to execute the steps needed for taking these technologies to the market.”

Gas monitoring in premature baby lungs

A new article on the topic of gas monitoring in premature baby lungs is now published in Journal of Biophotonics. The article "Computer simulation analysis of source-detector position for percutaneously measured O2-gas signal in a 3D preterm infant lung" is co-written by several members of the staff at Gasporox and GPX Medical, for example CEO Märta Lewander Xu.

Gas monitoring in maxillary sinus

The need of improved tools for diagnostic support of sinus related disorders
The paranasal sinuses are cavities within the scull and are ventilated through the nose. By using GASPOROX unique technology it is possible to easily measure the amount of gas and the gas composition inside the sinus and gain valuable clinically important information.
There is a definite need for accurate diagnosis of Sinusitis and the current methods are often inaccurate and resource intensive. Sinusitis is one of the most common illnesses where patients are prescribed antibiotics. A study has shown that only half of the patients with the diagnosis sinusitis in reality had sinusitis, i.e. half of them had an incorrect diagnosis and antibiotic drugs were unnecessarily prescribed in twice as many of cases compared to what was really medically justified. It is a well known fact that today’s high prescription of antibiotics contribute to the development of resistant bacteria. Thus, there is a great need to already at the primary care centres easily and accurately be able to make a correct diagnosis when a patient is experiencing problems with his sinuses.

How to measure

The technology concept
The principle of the measurement procedure is that the laser source is placed on the cheek in order to reach the sinus and non absorbed light is detected on cheek. The method utilizes low-power, scattered laser light that is sent through the sinus and is non-invasive and unharmful to the patient.

The technology benefits
The feasibility of the technology has been shown in a clinical study where diagnostic correlation between CT scan and the GASMAS method was shown*.
The benefits with the GASMAS method as diagnostic support are several. The method is easy and quick and the result is received without delay and resource demanding activities. As the technique does not involve ionizing radiation of the sinuses in the skull it is very safe for the patient. It also means that the health sector avoids costly and time-consuming investigations as well as decrease prescription of antibiotics.

Gas monitoring in premature baby lungs

In children born very early (before pregnancy week 28) lung function is one of the most critical aspects. In today’s neonate intensive care, lung function must be regularly monitored using mobile X-ray scanners, and the oxygen saturation must be verified by sampling arterial blood. GASMAS holds the promise to replace these methods with a simple, non-invasive method that can be applied continuously to monitor the state of the lungs. GASMAS technology can be used to monitor the oxygen content directly inside the lungs, and resolve which lung lobes are active.
