Hi, I'm down in Maryland so I'm not sure what we'll get hit with, but after receiving an email from the electric company telling us to prepare to be without power for at least 72 hours I knew I needed a way to do my nebs. I ran out to radioshack and got an outlet converter that plugs into your car cigarette lighter. And filled the car up with a full tank! That way I can plug in my machine, or phone, or computer... really anything and be all set.
They had a few different options: one was 30$ for 75 amps/watts (I can't remember what it was measured in) 40$ for 150 amps/watts 60$ for 175 amps/watts and then one with 3 different outlets - not sure of the amperage. I'm sure any wireless store would have one-- my dad bought his from Verizon.
I remember having one of these as a girl and it came in hand so often that it's worth spending the money to get one. I doubt that the vest would be able to be used with it, since it doesn't offer a lot of amperage, but as far as nebs go I'll be covered. Even if you just get the 30 dollar one you won't have to miss a single dose! And you'll never worry about power outages again (as long as you have access to a car).
As far as saving the nebs A fridge will keep its temperature for 24 hours without being opened. Turn it to the coldest setting as soon as possible so it will stay colder longer. I have about 12 slow melting ice packs, a few regular icepacks, extra ice cubes, and I froze some plastic containers filled with water too. I have almost a 3 months supply of pulmozyme I don't want to lose so I'm taking no precautions! haha if we lose power for more than 24 hours I plan on moving over some ice packs & ice into a styrofoam cooler that came with the mail order pulmo.
