One of the things that was drilled into my head when in the military was first aid, which we were all required to learn. Those of us that worked around high voltages were also required to know CPR, including passing the American Red Cross CPR course. I have used CPR on three separate occasions, none of the victims lived to tell about it. I have been told by my wife’s cousin, who is an ER doctor, that that result is fairly typical, especially in older persons with heart conditions, which in two instances was the case.
I have always carried a standard first aid kit in my truck. Things like band aids, gauze pads, sterile water, Hydrogen Peroxide, medical tape, splints, antimicrobial cream, blankets, etc. Nothing hugely complicated, something like this unit. I have used it recently at accident scenes, which I tend to stop for if it looks like they need help.
To complete this, I have also purchased an AED. As one medic once said, if a heart gets shocked out of sinus rhythm, it can be easily shocked back into sinus rhythm provided it is done quickly. Working on high voltage power supplies always entails some risk, even when all safety procedures are followed. As little as 60 mA can cause arrhythmia. Dry skin has a resistance of about 300 ohms, which means that 180 VDC is the threshold for fatal shocks. This value is much lower if the skin is wet. Any shock received through either hand is likely to travel through the chest and can effect the heart. Many of the transmitter sites we service are remote, medical help may be 30-60 minutes away under good conditions. Having an AED on hand is just a little bit of extra insurance, that will hopefully never have to be used.
CPR procedures have been updated in the last few years, if one has not recently reviewed them, it might be worth while to take a refresher course. I will say, hands only CPR is an improvement not only because it is more effective, but also because most heart attack victims vomit and loose control of their bowls. Reduced contact with someone else’s stomach contents is always welcome. This AED came with a training video CD. While AED’s are designed to be intuitive, having training on their use is always a good idea. The Red Cross also gives classes that include the use of an AED with hands only CPR.
