It is the question many healthcare professionals are – or should – be concerned with in the light of recent events. To protect their cardiac patients, it is essential for healthcare practitioners to evaluate their heater / cooler units for NTM (non-tuberculosis mycobacterial) contamination.

There is a growing number of reported cases concerning NTM infection in the operating rooms:

  • Health Canada identified NTM Bacterial infection concern in 12 models of heater/cooler units.
  • Quebec doctors have already reported at least two cases of NTM infection.
  • CDC estimates that in hospitals where at least one infection has been identified, the risk of a patient getting an infection from the bacteria was between about 1 in 100 and 1 in 1,000.


The Key: Evaluate Water and Air in Contact with the Heater/Cooler Units

NTM is caused by Mycobacterium chimaera – a slow growing NTM that is a member of the Mycobacterium avium complex, which is widespread in nature and can be found in soil and water, including drinking water sources. The contamination can spread through water and air. Heater-cooler devices include water tanks that provide temperature-controlled water to external heat exchangers or warming/cooling blankets through closed circuits.
