Particle monitoring in medical environment

Particle monitoring is crucial when it comes down to controlling the indoor air quality (AQ) in hospitals. Particles are well known as carriers of micro-organisms and therefore the amount of particles in the indoor air should be assessed and controlled.

In order to permanently assess the particle concentration in the hospital’s indoor air, UZ Leuven has a strict monitoring plan. In the past the biggest Belgian hospital and one of the biggest hospitals in Europe was performing particle monitoring with handheld particle monitors. Although this was not a wrong way to monitor AQ, there are some disadvantages of this method:

 Relative high price of the handheld particle monitors.
 Single point measurements (time and space).
 When measurement is performed can be influencing the results (humans produce a lot particles all the time).
 Time consuming for the people performing that kind of monitoring.

The employees need to do the same tour every day (going to the location, taking the measurement, turn back to their working places etc.). Moreover the particle counts need to be downloaded on their computers and processed for presenting in understandable way. With the challenging task to improve this not so effective method, InsightAir is installing in the premises of UZ Leuven a Medical Air Quality Sensor network.














The usage of freestanding AQ sensor network, is related to the following improvements:

 4-dimensional measurements are possible through particle monitoring at multiple locations. Those AQ monitors are logging 24/7 the air quality fluctuations.
 Different other parameters are also logged (temperature, relative humidity etc.)
 There is no external influence, because the results are being logged fully automatic.
 Instant access to all the data via InsightAir dashboard.
 Easy way of sharing data with the management and colleagues.
 Alerts and notifications, when certain limits are exceeded.

Through the installation of  InsightAir Medical AQ network, UZ Leuven saves lots of time
for performing the particle monitoring by the employees. The result was return of the investment in less than one calendar year. Moreover the hospital has signed a Service Level Agreement with InsightAir, making sure the particle monitors are well serviced and allowing an instant repair or spare sensors when needed. In the future, the InsightAir sensor network will be expanded to other facilities in the
hospital. Other InsightAir air quality sensor, measuring parameters in the air such as CO2,
VOC’s, temperature etc. can easily be added in the future to this sensor network.
