Hi,I am Dr. Shanthi.E (General & Family Physician). I will be looking into your question and guiding you through the process. Please write your question below.
My friend passed out on his way up the stairs. His wife got there 10 minutes later. By then his tongue and ears were bluish. He's in ICU, with a faint but steady pulse. The hospital staff doesn't know yet what happened. What are the possibilities, please? Thank you.
