I really appreciated Steven Harris sharing about what he is doing for his mother. My mother-in-law lives with us and I worry about what to do with her various medical devices running on electricity during an outage. Using an inverter on our car makes sense for the nebulizer (used to vaporize and deliver medicine to the lungs) since that doesn't run very long but now that I'm writing this, I'm wondering how many amps it draws. I'll have to check.
I'm also worried about the oxygen machine she uses at night. That's the bigger problem. It runs all night and draws oxygen from the air. That's good because I don't have to worry about stocking enough oxygen canisters (because how many is "enough" in a disaster?) but I'd like to be able to fill my own canisters using the same machine and run the machine during a disaster.
I'm going to look at the amps of these machines right now... OK... here are the numbers...
Inspiration Elite Nebulizer Model HS456 draws 2.0 amps.
Respironics Millennium 600 Oxygen Concentrator draws 4.8 amps.
It's difficult to tell how much the Oxygen concentrator produces because there are two numbers... 92 +/- 4% @ 5 LPM and 92 +/- 2% @ 2 LPM. I assume LPM is Liters Per Minute.
I have the meter than tracks watts and amps that Steven Harris recommended. I think I'll hook that up and take a reading.
Here is a link to the Oxygen Concentrator with the criticism that it draws too much power compared to more modern devices...http://www.phc-online.com/Oxygen_Concentrator_p/respironics_m600.htm
