Keeping Your Hospital Bed Working During a Power Outage

The power goes out at 2 a.m. during a thunderstorm. The hospital bed that your spouse or parent depends on goes completely silent. You press the remote. Nothing. You try again. Still nothing. Somewhere in the back of your mind, you realize the alternating pressure mattress pump has also stopped, and you have no idea how long ago.

This is the scenario caregivers describe more than almost any other home care emergency. And the reason it’s so frightening isn’t just the darkness, it’s the sudden helplessness. An electric hospital bed is enormously capable when it has power. Without it, most caregivers don’t know where to begin.

Power outages driven by severe weather have increased sharply in recent years, with roughly 80% of major U.S. outages tied to weather events.¹ Keeping your hospital bed working during a power outage is not a fringe concern, it’s a core part of home care planning. This guide walks you through exactly what to do, in order, both in the moment and before the next storm arrives.

Two Things Fail at Once, and They’re Not the Same Problem

Understanding what stops working when the power cuts out is the first step to staying in control. There are two separate, power-dependent systems to address, and they have different failure modes and different urgency levels.

The bed motor stops. A full-electric home hospital bed, like the Aura Premium, operates the head, knee, and height adjustments via electric motors. When power is interrupted, every one of those functions locks in place. You can’t raise the head section. You can’t lower the bed to a safe transfer height. If the person in the bed needs repositioning for comfort or safety, you cannot do it using the remote. If you’re not familiar with full-electric vs semi-electric vs manual hospital beds, this distinction matters: fully electric beds have no hand-cranked fallback unless you know where to look for it.

The alternating pressure mattress pump stops. If your care setup includes an alternating pressure mattress for home use, its pump requires continuous power to cycle the air bladders that distribute pressure across the skin. When the pump stops, the mattress begins deflating. On some models, full deflation happens in under five minutes. The person in the bed ends up lying directly on the metal frame, creating serious pressure injury risk. Research on power outages and community health shows that outages disproportionately harm older adults and people with chronic conditions, contributing to significant increases in emergency department use and adverse health outcomes.²

These two systems need to be addressed separately. The sections below tackle each one.

The Emergency Hand Crank: What It Is and Where to Find It

Here is the single most important piece of information in this article, and the one most caregivers discover too late: almost every full-electric hospital bed ships with a manual hand-crank bar, and almost no one knows it’s there until they’re in crisis.

The crank is the low-tech backup built into the bed for exactly this situation. On most full-electric hospital beds, there are up to three cranks accessible from the foot end of the bed frame:

• Middle crank: raises or lowers the overall bed height
• Left crank: adjusts the backrest (head section / fowler position)
• Right crank: adjusts the knee section

The crank bar itself is typically stored under the mattress deck near the foot end, or clipped to the underside of the frame. On some beds it is a single removable bar that inserts into each socket in sequence.⁴

The Anesthesia Patient Safety Foundation formally recommends that caregivers and clinical staff receive training on manual overrides for electric beds before an emergency arises, not during one.⁵ The reasoning is straightforward: a crisis at 2 a.m. is not the moment to be reading a manual.

What to do right now:
1. Go to the foot end of the bed and look underneath the mattress deck.
2. Find the crank bar, it may be attached to the frame or stored in a sleeve.
3. Practice inserting it into each socket while the power is on so you know what it feels like.
4. After use, the crank must be stored safely, it is not designed to stay in the socket during normal use.

When SonderCare delivers and installs an Aura Premium home hospital bed, the white-glove setup walkthrough covers the emergency crank location and operation as part of the standard orientation. This is one of the details that gets skipped when a DME company drops off a bed and leaves, and it’s exactly the kind of gap that creates a 2 a.m. crisis. Keep the crank bar somewhere you can find it in the dark.

Your Air Mattress Is the Urgent Risk, Act Within 20 Minutes

If your care setup uses an alternating pressure mattress, the mattress pump is your more urgent concern in a power outage, more urgent than the bed motor itself.

Pressure injuries can begin forming in as little as 20 minutes of inadequate pressure distribution, and damage sustained over hours can progress to stages that are difficult or impossible to reverse. When the pump stops cycling, the clock starts.

Immediate steps when the pump stops:
1. Turn on a flashlight or phone light so you can see clearly.
2. Manually reposition the person onto their side using pillows or foam wedges for support, even a 30-degree tilt substantially reduces pressure on bony prominences.
3. Set a timer to reposition again every two hours for as long as the pump is off.
4. Check the skin at each turn: the back, hips, heels, and shoulders are the highest-risk areas.

For detailed guidance on safe repositioning schedules, see our guide on how often to reposition a bedridden patient, which covers manual turning techniques and timing standards for different risk levels.

The mattress pump will almost certainly need more power than the bed motor to run continuously, sizing your backup correctly means accounting for both.

Backup Power Options: Which One Is Right for Your Setup

There are three main backup power options available to home caregivers, ranging from a basic $80 unit to a whole-house generator. The right choice depends on how long you typically lose power, which devices need to run, and your budget.

Option 1: Uninterruptible Power Supply (UPS)

A UPS plugs into the wall and keeps itself charged continuously. When the power cuts out, it switches to battery power instantly, no startup delay. Most UPS units sized for home medical equipment provide 30 to 90 minutes of runtime, which is the standard buffer originally designed for safe equipment shutdown in clinical settings.³

A UPS is adequate for brief outages where you need to reposition the bed safely and then transfer the person to a manual sleeping arrangement. It is not designed to run an alternating pressure mattress pump for hours.

Best for: Short outages (under 1 hour), repositioning the bed once, buying time while assessing alternatives.
Approximate cost: $80–$300 depending on capacity.

Option 2: Portable Power Station

A portable power station (sold under brands like EcoFlow, Jackery, and BLUETTI) is a large rechargeable battery with AC outlets, USB ports, and sometimes solar input. Unlike a UPS, it’s designed for sustained multi-hour use.

A 500–1,000 Wh power station can typically run an alternating pressure mattress pump continuously for 8 to 14 hours, plus occasional bed motor use. A 1,500–2,000 Wh unit extends that to 20+ hours and can also support a CPAP machine on the same circuit.

Sizing guidance: Check the wattage label on each device in your care setup. Add them up to estimate continuous draw. Divide your power station’s watt-hour capacity by that number to estimate runtime. Multiply by 0.85 to account for conversion losses.

SonderCare’s Portable Battery Back-Up ($149) provides four-outlet backup protection and is sized for emergency bed lowering and short-duration repositioning, an accessible entry point if a full power station isn’t in the budget yet.

For a complete overview of what accessories support your care setup in an outage and beyond, see our guide on hospital bed accessories every caregiver needs.

Best for: Outages lasting 4–24+ hours, running the full care stack (bed + mattress + CPAP).
Approximate cost: $500–$2,000 depending on capacity.

Option 3: Whole-House Generator

A standby or portable generator provides the closest thing to seamless grid replacement. A properly sized generator can run all medical equipment in the home simultaneously, for days, as long as fuel is available.

The tradeoff is cost and complexity: standby generators require professional installation and start at $3,000–$10,000. Portable generators ($700–$2,000) require manual fuel management and careful outdoor placement to prevent carbon monoxide exposure.

For households in storm-prone regions where multi-day outages are realistic, the Gulf Coast, the Southeast ice belt, Tornado Alley, a generator is worth serious consideration.

Best for: Multi-day outages, multiple power-dependent devices, households with repeated outage history.
Approximate cost: $700–$10,000+.

Wattage Reference Table

Check the label on each device for exact wattage. Manufacturer-stated wattage is the most reliable figure.

Register Your Home as a Medical Priority, Right Now

This section addresses the most consistently underreported resource available to home caregivers: utility company medical priority programs.

Most U.S. electricity providers maintain a Life Support Registry or Medical Baseline Program, a list of customers whose addresses are prioritized for faster power restoration because they have medical equipment that depends on electricity. Registration typically takes a single phone call or online form. The cost is zero.

Benefits of registration vary by utility but often include:

• Priority notification before planned outages
• Faster crew dispatch after unplanned outages
• Proactive welfare checks from utility representatives or local fire departments during extended events
• Advance notice in some jurisdictions when grid load-shedding is planned

The HHS emPOWER program provides federal, state, and local emergency planners with data on Medicare beneficiaries who depend on electricity-powered medical equipment, and uses that data to direct emergency response resources to the addresses most at risk. Registering locally amplifies this protection.

To register, call your utility’s customer service line and ask specifically about their Life Support or Medical Equipment priority program. They will typically ask for a physician’s confirmation of the equipment dependency. Some county emergency management offices maintain separate registries that can connect you with a generator loan program or in-person check-in during extended events.

For guidance from the American Lung Association on preparing as a medical device user, see their power outage preparation resource, it covers notification systems, backup power, and utility contact steps in more detail.

Build Your Pre-Storm Checklist

The goal of this checklist is to move from reactive to prepared, before the next outage, not during it.

One-time setup tasks (do these now):
– [ ] Locate the emergency hand crank on your hospital bed and practice using it
– [ ] Register your address with your utility’s Life Support program
– [ ] Register with your county emergency management office
– [ ] Call your DME company or hospice supplier and ask what their power-outage protocol is for your rented equipment
– [ ] Purchase or identify your backup power tier (UPS, power station, or generator)

Before each storm season:
– [ ] Fully charge your portable power station (check monthly if not already)
– [ ] Test the UPS by pulling the plug briefly to confirm it switches over
– [ ] Confirm the hand crank is still accessible and stored where you can find it in the dark
– [ ] Review your device wattage list and confirm your power station can run the full stack

During an active outage:
– [ ] Reposition immediately if the air mattress has stopped
– [ ] Use the hand crank to lower the bed to FallSafe height if needed
– [ ] Switch your mattress pump and bed to the backup power source
– [ ] Reposition manually every two hours if the pump remains off
– [ ] Contact your utility’s outage line and reference your medical priority registration

Frequently Asked Questions

Does my hospital bed have a built-in battery backup?

Most full-electric home hospital beds include a small 9V battery for a single emergency lowering only, enough to bring the bed to its lowest position one time if the grid goes out. The Aura Premium and Aura line include this feature, which SonderCare recommends replacing every two years. This battery is not designed to run the bed through multiple repositioning cycles; that requires a separate external backup power source.

How long before pressure injuries start forming if my air mattress goes flat?

Pressure injuries can begin developing within 20 minutes of inadequate pressure support on bony prominences. The faster you reposition manually, the lower the risk. Any redness that doesn’t blanch (turn white) when pressed is an early warning sign that requires immediate repositioning and monitoring.

What size power station do I need?

For a hospital bed and alternating pressure mattress pump together, a 500–1,000 Wh portable power station provides approximately 6–12 hours of continuous mattress pump operation plus occasional bed movement. If you also need to power a CPAP machine or oxygen concentrator, step up to a 1,500–2,000 Wh unit. Use the wattage table above as a starting point, then check the labels on your specific devices.

Can I register my home as a medical priority household?

Yes. Call your electricity provider and ask specifically about their Life Support Registry or Medical Baseline Program. It costs nothing, and it takes a single phone call. Most utilities require a physician’s confirmation of equipment dependency, which your doctor or home health agency can provide. For federal-level context on how this data is used in emergencies, the Anesthesia Patient Safety Foundation’s guidance on power failure preparation provides detailed background on clinical-level power planning that translates directly to home care settings.

What if I have no backup power and the power just went out?

Act immediately on the mattress: reposition the person onto their side manually, supported by pillows or a rolled blanket. Use the hand crank to adjust the bed to a safe position. Check the skin at each turn. Contact your utility’s outage line and reference any medical priority registration you have. If the outage is likely to be extended and you cannot manage safely, contact your local emergency management office, they often have resources specifically for households with medical equipment needs.
