Scientific evidence
Our innovations are backed by scientific evidence
TcAF and Opragon have undergone scientific studies in a number of different contexts. Statements regarding the medical need for ultra-clean air in Operating Rooms, the correlation between lower bacteria levels and lower SSI rates as well as statements related to the performance of Opragon are all supported by several pieces of scientific evidence.
Each statement we make is linked to specific pieces of literature. For example, “Surgical site infections are correlated with airborne bacteria levels” – is linked to supporting evidence from several papers. Use the buttons below to see all evidence for our most important statements.
An extensive list of all scientific literature – in total 45 pieces – that supports Opragon is available on request using the download button below.
Note: TcAF is in some articles termed “TAF”. Since 2018, Avidicare uses TcAF in order to avoid confusion with Turbulent Mixing Airflow, which in some countries are abbreviated as TAF.

Statements are evidence-based
“Surgical site infections are correlated with airborne bacteria levels”
Read the evidence“Particles carrying bacteria are continuously spread to the air from people in the operating room or from adjacent rooms in the case of door opening”
Read the evidence“The majority of the bacteria contaminating the surgical wound are likely to have reached it by the airborne route”
Read the evidence“Indirect contamination of the surgical wound via medical devices occurs as well as direct airborne contamination”
Read the evidence“Microbiological air sampling is a better method for investigating operating room air quality”
Read the evidence“The size of airborne particles carrying micro-organisms are in the order of a few micrometers”
Read the evidence“The main measures to prevent SSI are antibiotics, the use of suitable ventilation, surgical clothing, staff numbers and behaviour”
Read the evidence“Post operative infections not only cause suffering – they are also costly”
Read the evidence“Antimicrobial and antibiotic resistance is an increasing threat”
Read the evidence“Downward airflow is effective regarding reduction of airborne bacterial counts and velocities of at least 0.3 m/s are needed to break body convection”
Read the evidence“TcAF ventilation keeps the whole operating room ultra-clean”
Read the evidence“TcAF ventilation is energy efficient and provides a comfortable working environment”
Read the evidence“TcAF ventilation benefits validated using CFD”
Read the evidence“TcAF installation reduces risk for SSI – 3% to 1% in large study”
