This protocol provides guidance on how best to perform and process environmental water and air sampling, from heater-cooler units and environments where these units are in operation, in order to recover slow growing mycobacterial species.
The environmental samples referred to in this document are:
- water samples from heater-cooler units (used in cardiopulmonary bypass surgery)
- air samples in environments where heater cooler units are in operation (in support of cardiopulmonary bypass surgery)
This is an interim protocol generated as part of an incident response and will be finalised when more data is available.
