Can clothing systems and human activities in operating rooms with mixing ventilation systems help achieve 10 CFU/m3 level during orthopaedic surgeries?
Cao, Guangyu; Pedersen, Christoffer; Zhang, Yixian; Drangsholt, Finn; Radtke, Andreas; Langvatn, Håkon; Stenstad, Liv-Inger; Mathisen, Hans Martin; Skogås, Jan Gunnar (Journal article, 2021)The level of airborne microbial contamination in operating rooms (ORs) is an important indicator of indoor air quality and ensures a clean surgical environment. It is necessary to research how different factors affect the ... -
Can we meet the requirement for ultra-clean operation room (10CFU/m3) with dilution ventilation?
Pedersen, Christoffer; Cao, Guangyu; Drangsholt, Finn; Stenstad, Liv-Inger; Skogås, Jan Gunnar (Journal article; Peer reviewed, 2019)The objective of this study is to analyse what conditions may, and may not take place during surgery in a dilution ventilated operating room (OR), to fulfil an ultra-clean requirement (10 CFU/m3). To achieve the objective, ... -
Characterization of the airflow distribution in close proximity to a patient in operating rooms with laminar airflow at St. Olavs Hospital
Storås, Madeleine Charlotte Aviles (Master thesis, 2017)This master's thesis has investigated the airflow distribution in close proximity to a patient in a laminar airflow ventilated operating theatre. The assignment was divided into three different scenarios, that each consider ... -
Characterization of the airflow distribution in close proximity to the patient in an operating room
Nilssen, Anders Mostrøm (Master thesis, 2018)In modern hospitals, among surgical patients surgical-site infections (SSIs) are the most common hospital-aquired infections accounting for 36% of nosocomial infections. Tremendous efforts have been made to understand the ... -
Design av et interaktivt, telemedisinsk verktøy mellom primær- og sekundærhelsetjenesten.
Fry, Kristine Rise (Master thesis, 2017)Bakgrunn: Antall pasienter som blir henvist til sykehus og til akuttmottaket stiger stadig. For å redusere antall pasienter som unødvendig blir henvist til spesialisthelsetjenesten, er det behov for en desentralisering ... -
Experimental measurements of surgical microenvironments in two operating rooms with laminar airflow and mixing ventilation systems
Cao, Guangyu; Kvammen, Ingeborg; Hatten, Thea Amalie Solberg; Zhang, Yixian; Stenstad, Liv-Inger; Kiss, Gabriel; Skogås, Jan Gunnar (Peer reviewed; Journal article, 2020)At present, laminar airflow (LAF) systems and mixing ventilation (MV) systems are two commonly used ventilation solutions for operating rooms (ORs) to ensure the required indoor air quality. However, recent studies have ... -
Experimental study on the effect of exhaust airflows on the surgical environment in an operating room with mixing ventilation
Xue, Kai; Cao, Guangyu; Liu, Meng; Zhang, Yixian; Pedersen, Christoffer; Mathisen, Hans Martin; Stenstad, Liv Inger; Skogås, Jan Gunnar (Peer reviewed; Journal article, 2020)Due to the requirements of indoor environment parameters, including temperature, humidity, air speed and indoor quality, the design of the surgical environment is a very complex task. However, with limited studies on the ... -
The impact of air change rate on the air quality of surgical microenvironment in an operating room with mixing ventilation
Zhang, Yixian; Cao, Guangyu; Feng, Guohui; Xue, Kai; Pedersen, Christoffer; Mathisen, Hans Martin; Stenstad, Liv-Inger; Skogås, Jan Gunnar (Peer reviewed; Journal article, 2020)Transmission of airborne microbe-carrying particles (MCPs) is one of the key factors causing surgical site infection during surgical procedures. In operating rooms (ORs) with mixing ventilation, air change rate may determine ... -
Suitability evaluation on laminar airflow and mixing airflow distribution strategies in operating rooms: A case study at St. Olavs Hospital
Fan, Minchao; Cao, Guangyu; Pedersen, Christoffer; Lu, Shilei; Stenstad, Liv Inger; Skogås, Jan Gunnar (Journal article, 2021)Operating room (OR) is an indispensable department in a hospital, while its ventilation system is an important engineering solution to ensure safety for surgical procedures. Suitable ventilation system in the OR should be ...
