General Statistics on Cardiac Arrest ...

All,

My organization is considering purchasing an automatic
external defibrillator. Here is my question:

Given 800 attendees on site, once-a-week for 1.5 hrs, can
someone calculate the likelihood that someone will suffer
a cardiac arrest (on site) during the next 1, 3 or 5
years? I would assume that my population has the same
baseline risk as any generalized population in the US.

Obviously an incorrect assumption - I would assume that
your organization is primarily adult. Age and gender are
critical factors.

Also, average age is only ONE consideration, an organization
with an average age of 40 could all be 40, or could range
from 20 to 90

Quoted message said:

If time-of-day is a weighting factor, then these attendees
will be on site between 9AM and 12PM.

Possibly TOD is a factor, but no reliable stats exist
on tis yet

Quoted message said:

If you can cite a reference, and provide the answer as a
function (so I could recalculate liklihood after changing
attendees and time on site), please post.

WHERE are you having this convention? - at Big Meadows Lodge
on top of a mountain in Virginia. or at the Baltimore
Convention Center, where you are three blocks from the R
Adams Crowly Shock-Trauma center?

Likewise, have you checked to see if the facilities you are
using already have one - telling bidders that having a unit
counts points in evaluating convention sites will have a
salutatory effect.

What has past experience been?

and, finally, what is your total budget? is the cost really
material to your organization, or the peace of mind more
important.

Thank you in advance,

Okay... don't have any activities on a Monday morning. Serve
red wine and [censored] mushrooms and eat dessert first, and
make everybody laugh. And you will not have anyone suffer
cardiac arrest.

Ted: re avg age - very good point. 3/4's of CHD occur at ages over
65. Another factor - the socio-economic level of attendees
- the higher, the lower the incidence of CHD.

There is a mystic belief in Gauss curves and
population cohorts.

In fact, general populations are usually like inverse Perl
curves, and specific populations (such as members of an
organization) tend to be Poisson curves.
