At the weekend we lauded the actions of colleagues who saved the life of Napier Intermediate teacher Benita Mareikura.
While one teacher began CPR on Mrs Mareikura, the deputy principal headed for a defibrillator.
The knowledge of CPR and the awareness there was a defibrillator nearby were essential to saving Mrs Mareikura's life.

This is a result of people giving up their time and effort to do a first aid course, a readily available course that most of us think would be a good idea...but also an easy thing to put off.
I'd put it off, despite having active and accident-prone family members and living near a crash black spot.
Eventually I needed to do a course, for work, and went along expecting to be a little bored.
I wasn't bored, in fact it was fascinating. A lot has changed since I did first aid at college.
Two days later there was a crash outside my house. With "DRSABC" and "30 to 2 no matter who" still fresh in my mind I went through the drill.
Sadly, there was nothing I could do for the driver, who was killed instantly. But that drill stopped me from rushing about in a panic. I could check the other victims - all unhurt - and relay information to emergency services.
No, it was not ideal. But the security blanket of having done that course...priceless. I urge everyone who gets the chance - please, do a first aid course. You could save a life.
