What are sternal precautions after heart surgery?

Sternal precautions are the movement rules that protect your breastbone while it heals from a sternotomy — the incision used for most open-heart and bypass surgery. In plain terms: don't lift, push, or pull more than about 10 pounds with both arms (5 with one arm), don't put your body weight through your arms, and don't reach behind your back or overhead. Bending at the waist, notably, is NOT restricted — a genuine difference from the no-bending rule this site's knee and hip hubs describe.

The fact

Sternal-precaution weight limits after a standard sternotomy start at under 10 pounds using both arms, or under 5 pounds using one arm, for the first 6 weeks — and don't fully lift until as late as 24 weeks for the strictest incision category.

UW Medicine's own phrasing: 'Do not lift, push, or pull anything that weighs more than 10 pounds when using both arms, or 5 pounds when using 1 arm. (A gallon of milk weighs almost 9 pounds.)' OSU Wexner Medical Center's phased table independently corroborates the 10 lb figure and adds the fuller timeline: under 25 lbs at weeks 7-12, no restriction until weeks 12-24 for a standard sternotomy.

The rules, in the hospitals' own words

UW Medicine's occupational-therapy handout is the richest source found for this hub — a 6-page guide covering exact weight limits and the movement mechanics behind them. Four rules do almost all the work:

“Do not lift, push, or pull anything that weighs more than 10 pounds when using both arms, or 5 pounds when using 1 arm. (A gallon of milk weighs almost 9 pounds.)”

— UW Medicine, Activities of Daily Living with Sternal Precautions

“Do not put any of your body weight on your arms. Do not lean on your elbows. Do not use your arms to prop yourself up or adjust your position when you are lying down.”

— UW Medicine, Activities of Daily Living with Sternal Precautions

“Do not raise your elbow higher than your shoulders, unless you use both arms together and raise them only in front of your face. Do not reach behind your back or twist your body.”

— UW Medicine, Activities of Daily Living with Sternal Precautions

That third rule is why front-closure clothing matters so much on this hub's checklist — reaching behind your back for a bra clasp or a belt loop is precisely the motion it rules out. It's not a styling preference; it's the mechanism the hospital itself names.

The hug-a-pillow instruction

The single most concrete instruction across every source in this research pass: hug something to your chest, constantly, for weeks.

“Hug a pillow to your chest when you cough or sneeze. Do this also when you get in or out of bed, or when you move into a standing or sitting position. This will help to support your chest and decrease pain.”

— UW Medicine, Activities of Daily Living with Sternal Precautions

“Hug or hold the heart pillow to help ease pain during movements or coughing”

— OSU Wexner Medical Center, Sternal precautions following cardiac surgery

A hospital news article from Genesis HealthCare System explains why the pressure is worth bracing against at all:

“A cough pushes about 60 pounds of pressure against the sternum, while a sneeze places 90 pounds of pressure in the same area.”

— Genesis HealthCare System, Heart pillows: Pressure can reduce pain for cardiac patients

Genesis also confirms the pillow is standard-issue, not something you're expected to buy in advance: the hospital distributes about 3,500 firm heart-shaped pillows a year to cardiac patients at discharge, at just that one system. Any pillow purchase on this site's checklist is framed as a hands-free-strap upgrade or a spare, not a first-time necessity — see the full checklist for that honest framing.

The phased weight-limit table

OSU Wexner Medical Center's own precautions sheet organizes recovery into a 5-category table by incision approach (sternotomy standard, sternotomy strict, thoracotomy standard, thoracotomy strict, transfemoral) rather than by which specific procedure — CABG, valve repair, or replacement — was performed through it. The table below is the sternotomy-standard category, the majority pattern this hub covers; stricter categories extend some of these windows further.

Phased weight limits, standard sternotomy (OSU Wexner Medical Center)
Weeks after surgeryLifting / pushing / pulling limitNotes
1–6 Under 10 lbs (either arm alone or both together) UW Medicine's own comparison: a gallon of milk weighs almost 9 lbs.
7–12 Under 25 lbs No strength training or weightlifting until after week 12, per OSU's guide.
12–24 No restriction Full recovery of lifting ability, for the standard sternotomy category specifically.

Honest scope note: this table covers the sternotomy-standard category only. OSU's own sheet lists four other categories (sternotomy strict, thoracotomy standard, thoracotomy strict, transfemoral) with shorter or differently phased timelines — driving, for example, ranges from "after 6 weeks as tolerated" (sternotomy standard) to "after 1 week as tolerated" (transfemoral procedures). Follow your own surgeon's specific category, not a general one, especially if your incision wasn't a standard sternotomy.

Bending is allowed — a genuine difference from knee and hip recovery

This is the finding this research pass flagged as most worth stating plainly, because it cuts against a reasonable assumption: sternal precautions do not restrict bending at the waist. UW Medicine's own guide says so directly:

“To take off your socks or shoes... you can briefly bend over from a sitting position.”

— UW Medicine, Activities of Daily Living with Sternal Precautions

That's a real, sourced difference from this site's knee-replacement and hip-replacement hubs, both of which describe genuine bending restrictions (a 90-degree hip precaution, a bent-knee limitation) for weeks after surgery. Here, a reacher or grabber's job is avoiding arm-strain and overreach under the weight limits above — not compensating for an inability to bend, which simply isn't the restriction this surgery imposes.

What does the hospital actually give you?

At minimum, the firm heart pillow at discharge, confirmed by two independent hospital/rehab sources (Genesis HealthCare System, OSU Wexner Medical Center). Beyond that, UW Medicine's occupational therapy team may conditionally suggest, depending on your situation:

Every one of these is stated conditionally in the source material ("may suggest," "if hard") — not as universal, standard-issue equipment. That's why this hub's own checklist places them in "Depends on your situation," not the core essentials.

Why isn't any of this Medicare DME?

Not a data gap — a scope difference, confirmed by reading all 68 codes in data/coverage_status.json directly. Every code in that set is lower-extremity or general-mobility DME: walkers, canes, commodes, hospital beds and rails, patient-lift slings, seat-lift mechanisms, manual wheelchairs. None of it maps to a heart pillow, a front-closure bra, compression stockings, or a pill organizer — this surgery's equipment needs sit entirely outside the categories this dataset tracks.

One honest exception is worth naming directly, because a reasonable reader might ask about it: Medicare-covered hospital beds with head elevation (HCPCS E0250–E0266) do exist in the tracked code set, and some patients genuinely struggle to sleep flat after this surgery. But no hospital source fetched for this research recommends renting one specifically for heart surgery — Cleveland Clinic's own sleep-after-heart-surgery guidance is thin ("arrange the pillows... to decrease muscle strain"), and no other source mentioned a hospital bed at all. The connection between "some patients can't sleep flat" and "a head-elevating hospital bed is Medicare-covered DME" is this research pass's own editorial bridge — offered here as a question worth raising with your doctor if a recliner or sleep wedge genuinely isn't working, not as a primary recommendation.

This page explains what hospital patient-education sources and Medicare's published DME data say about the equipment and precautions on this checklist — it isn't a substitute for your own surgeon's or care team's discharge instructions, and it isn't a coverage determination for your specific claim. Weight limits, driving restrictions, and the full timeline genuinely vary by incision type and surgeon.
