Alcohol And Pulmonary Hypertension Blood Alcohol Level Question?

Blood alcohol level question? - alcohol and pulmonary hypertension

My brother, the former law was an alcoholic. He died in his sleep a few months ago of 50 years. We have received your report and autopsy said he died of chronic ethonalism (no surprise) CAD and pulmonary embolism. He said that his blood alcohol level was 0.149, essentially the middle is loaded again, when he died?
What is normal?
Thanks
