Question

Why aren’t the oxygen levels of ME sufferers routinely checked?

Answer

The simple answer is that routinely measuring oxygen levels in ME/CFS isn’t going to help with either diagnosis or management – unless there is some indication that the person may also have an underlying respiratory disease.

What can be helpful in relation to both diagnosis and management of ME/CFS is having a two-day cardiopulmonary exercise test – which measures dynamic oxygen uptake and use. But Cardiopulmonary Exercise Testing (CPET) testing is not easy to organise – as it is a hospital-based investigation.
