    • Experimental study on the exposure level of surgical staff to SARS-CoV-2 in operating rooms with mixing ventilation under negative pressure 

      Bi, Yang; Aganovic, Amar; Mathisen, Hans Martin; Cao, Guangyu (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-04-21)
      The purpose of this study was to reveal the exposure level of surgical staff to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) from the patient's nose and wound during operations on COVID-19 patients. The tracer gas N<sub>2</sub>O is used to simulate SARS-CoV-2 from the patient's nose and wound. In this study, concentration levels of tracer gas were measured in the breathing zones of ...

    • Experimental Study on the Surgical Microenvironment in an Operating Room with Mixing Ventilation under Positive and Negative Pressure 

      Bi, Yang; Heggebø, Frida Josefine; Harsem, Trond Thorgeir; Mathisen, Hans Martin; Aganovic, Amar; Cao, Guangyu (Chapter; Bokkapittel, 2021)
      Due to the outbreak of Covid-19, negative pressure operating room (NPOR) are strongly recommended to be applied to prevent spreading virus from infected patients to adjacent rooms during surgery procedures. However, there have been few experimental studies on the effect of OR pressure difference on the surgical microenvironment. This study aims to experimentally investigate the airflow distribution ...
