Our innovations are independently validated and backed by clinical evidence
Over 60 years of evidence demonstrates the correlation between airborne microbial bioburden and the rate of Surgical Site Infection (SSI). Lower airborne bioburden means lower SSI.
The performance of the Opragon system has been independently validated by leading experts in healthcare air quality in both the US and Europe. These studies have taken place under a range of different surgical conditions and procedures including measurement of airborne bioburden during active surgery. Â
Note: TcAF in some articles is termed âTAFâ. Since 2018, Avidicare uses TcAF in order to avoid confusion with Turbulent Mixing Airflow, which in some countries is abbreviated as TAF.

Statements are evidence-based
âSurgical site infections are correlated with airborne bacteria levelsâ
Read the evidenceâParticles carrying bacteria are continuously spread to the air from people in the operating room or from adjacent rooms in the case of door openingâ
Read the evidenceâThe majority of the bacteria contaminating the surgical wound are likely to have reached it by the airborne routeâ
Read the evidenceâIndirect contamination of the surgical wound via medical devices occurs as well as direct airborne contaminationâ
Read the evidenceâMicrobiological air sampling is a better method for investigating operating room air qualityâ
Read the evidenceâThe size of airborne particles carrying micro-organisms are in the order of a few micrometersâ
Read the evidenceâThe main measures to prevent SSI are antibiotics, the use of suitable ventilation, surgical clothing, staff numbers and behaviourâ
Read the evidenceâPost operative infections not only cause suffering â they are also costlyâ
Read the evidenceâAntimicrobial and antibiotic resistance is an increasing threatâ
Read the evidenceâDownward airflow is effective regarding reduction of airborne bacterial counts and velocities of at least 0.3 m/s are needed to break body convectionâ
Read the evidenceâTcAF ventilation keeps the whole operating room ultra-cleanâ
Read the evidenceâTcAF ventilation is energy efficient and provides a comfortable working environmentâ
Read the evidenceâTcAF ventilation benefits validated using CFDâ
Read the evidenceâTcAF installation reduces risk for SSI â 3% to 1% in large studyâ
