Back Up for BiPap Machine

[tootiredtocare]

I am in the South and we are getting ready to have an ice storm. I am so scared about the electricity going out, like it does every time we have an ice storm. I use a ResMed VPAP S bipap macihine and the H4i heated humidifier and have no idea what kind of battery back up to get or if you can put a bipap machine on a generator. Does anyone have any suggestions?

tootiredtocare, you had noted you needed to know how to setup a battery backup. I'll PM you with this information, but I think I can show you how to find the info you need.

On the ResMed site, there is a document that describes the battery sizing and hookup you might need (for your VPAP S [ or perhaps S8] unit and a Humidaire 4i unit, if I remember correctly):

Go to the top of page 13 and you will see a table that shows the battery power required. If you want to use the humidifier, you would need the more expensive "pure sine wave" inverter (converts form 12V DC battery to 110V AC outlet) with a 300 W sustained rating (with a peak of 500 W). Of if you turn off your humidifier (but allow the air to flow over the water ... making it a "passover" humidifier), then you can use a less expensive modified sine wave inverter rated at 150W sustained output and a peak of 200 or 300W. It's all in the manual.

You can then get a deep cycle battery to provide the power you need to sleep. Hope that helps.
