So when people talk about patients having a high lactate we think about them being sick, it can at times be easy to slip into thinking that this equals sepsis or maybe ischaemia. And whilst the presence of a high lactate in the context of infection and ischaemia is important to note, there is a lot more to interpreting a raised lactate than may first be apparent... So in this episode we’re going to delve down into lactate, have a think about what it is, what normal and raised levels are, consider the mechanisms behind it’s formation and breakdown and think about the causes of raised lactate. We'll then put this all together and have a think about how we can interpret and lactate levels ensuring we give the best treatment to our patients! Enjoy! Simon, Rob & James
