Sinusitis diagnostics

75% is predicted to be over-prescription.

New tool for sinus diagnostics is needed

About 20% of all prescribed antibiotics relate to sinusitis. Of this, it is predicted that 75% is prescribed even though the condition is caused by virus. There is a great need to easily and accurately make a correct diagnosis when patients experience problems with their sinuses, already at the primary care centers. The current methods are often inaccurate or require expensive resources.

Our solution

The paranasal sinuses are cavities within the scull, which are ventilated through the nose. With GPX Medical technology it is possible to easily measure the amount of gas and the gas composition inside the sinus and gain clinically important information already at the primary care centers.

The feasibility of the technology has been shown in a clinical pilot study where the correlation between assessment of the openness of the sinuses based on CT scan and the GASMAS* method was shown**.

The benefits with the GASMAS method for diagnostic support are several. The method is easy and quick and the result is presented without delay. 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 healthcare sector can reduce costly and time-consuming investigations as well as decrease prescription of antibiotics.
