It can be scary to see the power go out, especially if a person lives in a rural area, but it's even chilling when the power goes out right in the middle of town. We're so dependent on having power all the time that we might not consider the issues that may come about when the power goes dark. One of the most important things for people who may have health issues is to ensure portable items that must be used on a regular basis like pulse oximeters can be powered even if there's no electricity running into a home.
