WebMethemoglobin is a form of hemoglobin that does not carry oxygen. It is normal to have 1-2% of haemoglobin in this form. A high level of methaemoglobin would cause a pulse oximeter to have a reading of around 85% regardless of the actual oxygen saturation level. The higher percentage of methaemoglobin can be genetic or caused by exposure to ...
