GASERA ONE PULSE IN HEALTHCARE WORK SAFETY STUDY

GASERA ONE PULSE in healthcare work safety study to measure tracer gas, Sulphur Hexafluoride  (SF6). Healthcare workers treating patients infected with emerging and re-emerging viruses are aware of the risks they face, particularly aerosol transmission.

The aim of this study was to investigate and characterise the risk of potential aerosol transmission of infectious agents from patients to their HCWs in typical encounter scenarios in hospital isolation rooms to improve the work safety in healthcare.

A study conducted at the Turku University Hospital and University Hospital of Leicester investigated how the risks can be reduced by optimising ventilation methods as part of an engineering control approach to infection control and the study was based on laboratory experiments carried out in a full-scale isolation room model at TUAS Indoor Environment Laboratory.

In the study, tracer gas Sulphur Hexafluoride (SF6) measurements were carried out for several experimental cases to assess the effect of different parameters on the spreading of the patient’s exhaled airborne contaminants and the HCW’s exposure to them. In addition to the SF6 gas tracer, an organic live-attenuated vaccine virus tracer was used in this study for enhanced realism.

The SF6 tracer gas concentration was measured from the room exhausts and the inhalation of the HCW manikin. The sampling and measurements were carried out with the GASERA ONE PULSE multigas analyzer. This study demonstrates the applicability of the GASERA ONE PULSE in healthcare work safety research.

GASERA ONE PULSE is a versatile and easy to use multi-gas monitoring solution. It offers accurate ppb detection for a range of uses such as detecting Suphur Hexafluoride (SF6), anesthetic gas monitoring, occupational health and safety, among others.
