Hurricane and Power-Outage Planning for Houston Seniors on Oxygen or Dialysis

When a hurricane threatens Greater Houston, a parent on home oxygen or dialysis needs a plan that goes further than water and flashlights. Here's what to set up before storm season, not during it.

For most Houston families, hurricane prep means bottled water, batteries, and a plan for the windows. For a family with a parent who depends on a home oxygen concentrator or drives to a dialysis clinic three times a week, the stakes are different. A multi-day power outage or a flooded access road isn't an inconvenience — it's a medical emergency with its own clock. The reassuring part is that almost everything that protects a medically dependent parent during hurricane season gets set up in advance, not scrambled together once a storm enters the Gulf.

Why this is a different kind of hurricane prep

Harris, Fort Bend, Montgomery, Brazoria, Galveston, Liberty, Waller, and Chambers counties all sit inside a Gulf Coast region with a long history of hurricanes and tropical storms, and outages that stretch across multiple days are a familiar part of that pattern. For a parent whose medical equipment runs on household electricity, or whose treatment schedule depends on a clinic being open and reachable, the ordinary advice to "hunker down and wait it out" doesn't fully apply. The planning has to answer two separate questions: how does my parent keep breathing or stay on schedule for dialysis if the power is out for days, and what's the actual plan if the roads are impassable or the clinic itself has to close.

Register before the season starts, not during it

CenterPoint Energy's Critical Care / Medical Monitoring program

If your parent's home electric service runs through CenterPoint Energy — the transmission and distribution utility for most of Greater Houston — they can register as a Critical Care or Medical Monitoring customer if they depend on electric-powered, life-sustaining medical equipment such as an oxygen concentrator, ventilator, or home dialysis machine. Registration is done through CenterPoint's own application process on its website or MyAccount portal.

Read the fine print carefully, because it matters: CenterPoint states plainly that registering as a critical care customer "does not guarantee an uninterrupted, regular or continuous power supply." In practice, the program mainly gets your parent flagged for advance notice ahead of planned outages and keeps their account current for outage alerts — it is not a promise of priority restoration after a storm. That's exactly why the backup steps further down this guide aren't optional extras; they're the actual plan.

STEAR, the State of Texas Emergency Assistance Registry

STEAR is a free, voluntary registry maintained by the Texas Division of Emergency Management that gives local emergency planners and first responders additional information about who in their community may need help during a disaster — people with disabilities, medically fragile residents, and anyone who needs medical, transportation, or personal care assistance. You can register online at stear.texas.gov, by calling 2-1-1 (or 877-541-7905), or with a paper form available in English and Spanish.

Here too, the state is direct about the limits: "Registering yourself in the STEAR registry does not guarantee that you will receive a specific service during an emergency." What each county or city actually does with that information varies, and sharing it with first responders requires your consent when you register. Think of STEAR as making your parent visible to planners, not as a rescue guarantee.

The go-bag and backup plan for a parent on oxygen

Have this conversation with the durable medical equipment (DME) supplier now, while the Gulf is quiet:

• Ask about stand-alone oxygen tanks. A concentrator needs electricity to pull oxygen from the air; a compressed or liquid oxygen tank doesn't. Many suppliers will set a family up with backup tanks specifically for outage scenarios — ask what your parent's plan includes.
• Know the actual battery runtime. Portable oxygen concentrator batteries vary widely by model and by your parent's prescribed flow setting. Don't guess — check the manufacturer's spec sheet for that specific unit or ask the supplier directly, and keep at least one spare charged battery plus a car charger on hand.
• Teach a backup person. Make sure someone besides your parent — you, a home caregiver, or a trusted neighbor — knows how to switch between the concentrator and a stand-alone tank under stress, not just in theory.
• Keep documentation dry. Prescription information, the supplier's after-hours phone number, and copies of insurance cards belong in a waterproof bag alongside the equipment.

If a device's power is running low and there's no way to recharge it, don't wait to see what happens next. Call your parent's clinician or pharmacist for guidance, and know ahead of time where the nearest shelter or hospital with reliable power is, so relocating isn't a decision you're making for the first time in the middle of a storm.

The go-bag and clinic plan for a parent on dialysis

Dialysis adds a scheduling problem on top of the power problem: even with a generator at home, your parent still needs a functioning clinic to get to. The National Kidney Foundation's disaster guidance for dialysis patients centers on one piece of advice above all others — talk to your parent's clinic ahead of time about where they can go for treatment if the regular clinic closes or your parent has to evacuate, and write the name and phone number of that backup center down before you need it.

Pack a wheeled, waterproof go-bag with:

• Three days of water and kidney-friendly, non-perishable food
• Current medications and any medical devices your parent uses
• Copies of dialysis treatment orders and recent lab results
• ID and insurance cards
• A flashlight, extra batteries, a change of clothes, and a basic first aid kit

If a storm causes your parent to miss a scheduled treatment, don't improvise on diet or fluid intake based on general advice online — call the clinic directly, or reach the National Kidney Foundation's NKF Cares line at 855-653-2273 (Monday through Friday, 9 a.m. to 7 p.m.) for guidance specific to your parent's situation.

Generator and battery-backup safety

A portable generator or battery power station can keep a concentrator, CPAP machine, or refrigerated medication running through an outage, but two safety rules matter more than the convenience:

1. Generators run outdoors only — at least 20 feet from any door, window, or vent, following the manufacturer's setup instructions exactly. Carbon monoxide from an indoor or too-close generator is a real and fast-moving danger, especially in a home that's sealed up against storm winds.
2. Match the equipment to the load. Check the wattage a device actually draws against what your battery station or generator can deliver, and test the whole setup before hurricane season arrives rather than during the first outage of the year.

What your parent's facility is already required to have in place

If your parent lives in a nursing home, uses a Medicare-certified home health agency, or attends a Medicare/Medicaid-certified dialysis facility, that provider is bound by the federal CMS Emergency Preparedness Rule, which requires a written, facility-specific emergency plan, a communication plan for notifying patients and families during a disaster, and regular testing and drills. It's reasonable to ask the facility for a copy of how that plan applies to your parent, including what backup power they maintain and how they'll reach your family if phone lines are down. Note that this federal rule covers Medicare/Medicaid-certified providers like hospitals, nursing homes, and dialysis centers — state-licensed assisted living communities fall under separate Texas HHSC licensing rules instead, so it's worth asking an assisted living community directly what its own hurricane plan looks like.

Deciding whether to evacuate or shelter in place

This is ultimately a local decision that depends on your parent's specific medical needs, their evacuation zone, and the storm itself, so lean on official guidance rather than guessing: county-level emergency management offices and 2-1-1 are the right first call for medical needs shelter options or evacuation transport for a resident who can't self-evacuate, and that conversation goes far better when it happens ahead of a storm watch instead of during one. If your family decides to shelter in place, treat the oxygen and dialysis go-bags above as the actual plan, and set a clear trigger in advance for when it's time to leave anyway — a device battery that won't last the outage, floodwater reaching the home, or a mandatory evacuation order — rather than deciding that in the moment.

None of this requires you to guess what a utility or the state will do for your parent when a storm is bearing down — the registries, the supplier conversation, and the clinic's backup plan all work better set up weeks in advance. If you'd like help thinking through oxygen or dialysis logistics alongside a broader care plan — whether that's arranging reliable in-home care, comparing nursing homes with strong emergency preparedness, or simply having someone local double-check your parent's plan before hurricane season peaks — call Houston Senior Advisor at (346) 385-3815. There's no cost to talk it through.
