Keep It Running
The 72-Hour Power Plan for CPAP, Oxygen and Fridge Medicines
It is 11 at night and the house goes dark. The fridge goes quiet, and so does the CPAP on the nightstand. The power station in the closet might hold one night or five - and tonight is a hard time to find out which.
Know how many nights your battery runs the device and how many hours of backup oxygen you have, with your supplier's and pharmacist's answers written down before the next outage.

What you'll do with it
- Read the watts on your own labels and turn them into a battery size - about 400 Wh for each CPAP night at our 40 W planning number.
- Run one test night on the power station, so your real number replaces ours and a missing cable turns up while the stores are open.
- Count backup oxygen in hours with your supplier - cylinders x hours each - and write it on the Device Card.
- Ask the pharmacist how long each fridge medicine can stay out of the fridge, and write the answer on the Fridge Medicine Log.
- Make the calls on a calm day: your equipment supplier, the power company's medical list and your local emergency office.
