The likelihood is not "10-15% per person" that, during the operational lifespan of any given AED, that someone would have a heart attack at work, be treated by that specific AED, and have that treatment be life-saving. (That was the point of the meteor comparison.)

[Dave3of5]

The lifespan is 10-15 years depending on the model. Most people were at moderate risk, unfit, drinking alcohol, poor exercise, high stress job ...etc. For moderate risk 10-15% is the stat over a 5 year period. Most where moderate a few, 2 I think, were low and we had a few high and one very high risk given he'd possibly already had a small heart attack.

Also note that you didn't take into consideration that the device is used for all in the office so over the 5 years it's cost must be divided by the number of employees it will cover which in this case was around 12.

Again your Meteor comparison was extremely poor. You are comparing something that is very common, a middle aged person having heart attack, to something extremely uncommon a similar demographic being hit by a meteor. Also to note that you can't say it it £250 to protect from a meteor strike it would likely be extremely expensive to protect an office from that versus the insanely cheap £1100 to almost guarantee that any of us survive a heart attack.

I've eddited to show the actual lifespan of the AED which is 10-15 year

You are overestimating how often heart attacks in the office happen.

[Dave3of5]

Nope ...

[sokoloff]

How many same-office-colleague-years do you think you’ve had in your career? How many fatal heart attacks in the five across all those? For me, it’s “tens of thousands” and “zero”.

[Dave3of5]

That's rather personal but it is non zero.

It's clear to me you've made up your mind and you feel that spending the money is a waste for something that's so low risk so I don't see any point in continuing this conversation. If you do still work in an office I hope it never happens to you.

[sokoloff]

I do work occasionally in an office and have personally walked the floor to make sure the AEDs are correctly located on our floor plans and electronic signage and filed facility tickets to get the maps updated. (They were originally not correct.)

I believe in the benefit of AEDs. I also believe the average number of lives saved per AED installed in an office is way, way less than 1.0, and almost surely lower than 0.001 which was the point of this sub-thread.
