Methanol levels (measured and estimated) and treatment events. Included are measured methanol levels as well as estimated levels at the start and end of hemodialysis treatments #2 and #3. The drop in methanol levels during the Tablo treatment (HD#2) is highlighted in orange. The estimated methanol levels at the start and end of HD#2 and HD#3 were calculated assuming an endogenous methanol half-life (in the presence of ADH inhibition) of 52 h. ADH, alcohol dehydrogenase; ED, emergency department; HD, hemodialysis; UD, undetectable. To convert methanol levels from mmol/L to mg/dL, multiply by 3.2. *This level of 7.2 mmol/L (23 mg/dL) was drawn off of the dialysis catheter during treatment and is felt to be spurious. ^†Note that there was an 85-min interruption in HD#3 which is not graphically depicted
