CAOX3, I was thinking about the same thing when I memorized the number awhile back. I only have some guesses as to why they list that as a normal number, and the two most resonable in my mind is either it's a typo, or maybe it's weighted by newborns HR done within the first minute of APRGAR (HR >100 to get a +2 for P) since I know they aren't usually perfect, but those are only guesses.
I cracked open another book, Clinical Procedures for medical Assistants 7th Edition by Kathy Bonewit-West (
http://www.amazon.com/Clinical-Proc...ef=sr_1_1?ie=UTF8&qid=1304674379&sr=8-1-spell) which is a book we used in my clinical classes. I did not remember these numbers, but you can also see how different they are from my EMT book.
HR
Well-trained athlets 40-60
Adult (>60) 67-80
Adult (19-60) 60-100
Adolescent (12-18) 60-100
School-age child (6-12) 75-105
Preschool child (3-6) 80-110
Toddler (1-3) 90-140
Infant (Birth-1) 120-160
RR
Adult (>18) 12-20
Adolescent (12-18) 12-20
School-aged child (6-12) 18-26
Preschool child (3-6) 20-30
Toddler (1-3) 23-35
Infant (Birth-1) 30-40
This website also lists different numbers:

My point is that you should just know the general rule, that flat out remembering the numbers is probably not useful.
Since you mentioned it CAO, I was curious myself and did a Google to see why they would say 85. It appears my first guess was right, that it's usually slower within the first minute, but it starts to pick up before it slows down again.

Maybe it's a mistake in medicine too if they aren't using a stethoscope to obtain the HR?

Heh.
