Project Gutenberg was the first producer of free eBooks and though it
may not have emergency texts it does have all the classics for the
serious reader to download in PDF or MP3 Audio talking books while you
drive or on your PDA. ENJOY!
Another source would be the Michigan Electronic Library at www.mel.org.
Navigate to Mel Databases and find www.NetLibary.com. You will need
your Michigan drivers’ license to register then you will make a
username and password which will enable you to tons of online e-books
for free and there are CPR & First Aid books to view @ http://www.NetLibrary.com.
Suggested
web sites for your ACLS preparation: If you are already connected to
the Internet just point and click the links below. These sites are
for Healthcare Professionals in emergency medicine.
4. http://www.anesoft.com
This is a good site for not only ACLS, but in critical care,
bioterrorism and hemodynamics. The demo’s are free. Look in the Free
Stuff for videos to intubate, iv start ect.
5. http://www.vsu.com
This site is run by a doctor that specializes in ACLS education. I
think he’s the top in the nation but you have to go to him for his
training. He has put the interventions to music, you just got to hear
it to believe it. Listen to Asystole set to the blues, Bradycardia set
to the country 2-step and VT to the 70’s.
