※ 引述《GaARo (双主修>超修)》之铭言： : 请问有谁知道这是什麽意思??? : 原文: : The substance may cause effects on the cardiovascular system and blood :, resulting in lower blood pressure and the formation of methaemoglobin. Methaemoglobin is an abnormal type of haemoglobin that does not bind oxygen well. Normally 1-2% of people's haemoglobin is methaemoglobin, a higher percentage than this can be genetic or caused by exposure to various chemicals and depending on the level can cause health problems. A higher level of methaemoglobin will tend to cause a pulse oximeter to read closer to 85% regardless of the true level of oxygen saturation.
