In addition to annual validations of operating rooms, the standards also must be monitored continuously, to insure that information on air quality within operating rooms is available particularly during surgical procedures. Monitoring of particles provides the surgical team with insight into any disruptive factors and enables intervention to improve the situation. New regulations for proven traceability  (method of monitoring of the use of ORs and preparation rooms), particle monitoring is one of the main parameters that determine air quality.

In various studies at several hospitals in the Netherlands, combinations of particle monitoring and observations have been conducted during a large number of surgical procedures. This has led to surprising insights into the causes of exceedances of the ISO classes during such procedures. These studies have led to recommendations to improve air quality.
