skills videos - chest tube/central line insertion

Does anybody have any links to videos that demonstrate how to assist with chest tube/central line insertion? I have been searching on Google and Youtube and I haven't had any luck! On the floor I always end up with a patient who already has a chest tube or central line in place...but now that I am going to the ER there is a chance I will have to assist with insertion so I want to be prepared! Thanks!
Google is your friend.....type "How do I......Works every time.I believe there is a series of videos titled "how to." I can't find my link but it should work-because of those videos I passed my skills final with a 93%
