0:00.0	Hello, med students. My name is Zach Olson and thank you for downloading this week's
0:07.0	episode of the EM Clerkship Podcast. Here's your case.
0:19.2	Okay, everybody, we've got a 43-year-old male.
0:21.6	Had a sudden onset of headache about an hour ago, 10 out of 10 on the pain states he feels like he got kicked in the head.
0:28.6	No trauma, emesis times two, slight isolated right pupil dilation and sluggish to reflex to light.
