Why Ventilation Matters

Like all of natures elements, air is taken for granted; we breathe it every day and think nothing about its quality going into, or out of our lungs. For the majority of people the quality of air surrounding us, engulfing our bodies and infiltrating our internal organs and tissues has very little impact on our health when we are well, but when we experience illness and find we require the support of a healthcare setting, it is at this time we may fall into the category of being ‘vulnerable’ to other external factors that may cause secondary problems and ultimately harm, if we are not aware of the potential hazards.

‘Fit for Purpose’ ventilation within the built environment of the healthcare setting is essential to best practice and infection prevention adherence. Failures to comply with relevant, effective, efficiency and sustainability measures may compromise ventilation functions and result in patient susceptibility to infection and cancelled theatre lists.
Validation and verification reporting should not be a ‘tick box exercise’. It should comprehensively inform those named responsible for the safe operation and maintenance of the equipment.

Increased Health Risks

‘Increased health risks to patients will occur if ventilation systems do not achieve and
maintain the required standards. The link between surgical site infection and theatre
air quality has been well established.

Unacceptable Contamination Levels

If the ventilation plant has been installed to dilute or contain harmful substances, its failure may expose people to unacceptable levels of contamination. Proven breaches of the statutory requirements can result in prosecution and may also give rise to a civil suit against the operators.
