Exotag doesn't just monitor the core temperature of blood products, it also passively insulates them from ambient thermal conditions. The inside of our Exotag sleeve is filled with a lightweight insulating material and the top of the sleeve has a protective lid that can be sealed. By slowing down a blood product's heating we are able to extend the time it takes core temperatures to reach the 10 ºC threshold by around 30 minutes. This means your blood product can be left out for twice the amount of time without incurring a temperature violation. Our ongoing studies at partner hospitals are showing that 70% of RBC wastage are occurring from bags left out 30-60 minutes.
