Straight answers.

The Posthorax vest has been tested in four randomised controlled trials enrolling more than 4,800 cardiac surgery patients. The largest, published in 2013, reported that routine use reduces the relative risk of deep sternal complications by 54%. A 2024 systematic review pooled six randomised trials of thorax support vests covering 5,826 patients. Most chest supports on the market have never been tested this way — see the evidence page for the references.

By minimising friction at the sternal edges. Two cushions either side of the wound apply light front-to-back pressure, so coughing, standing and turning move the chest less. Patients then breathe more deeply instead of splinting — which is also how the device protects respiratory function.

Dehiscence is separation of the divided breastbone during healing, which can lead to infection and sometimes revision surgery. The trials measured sternal wound complications and additional surgical procedures within 90 days, and reported reductions in the vest groups. It reduces risk; no device removes it.

Day and night for six to eight weeks — the time bone needs to heal — unless your surgeon advises otherwise.

As soon as possible after surgery, ideally in hospital within the first 72 hours. In the published trials, patients who did not receive the vest inside 72 hours were counted as dropouts — early fitting is the protocol that was tested.

Either. Many patients prefer a light cotton shirt underneath at first. Correctly fitted, it should feel like a firm, even hug — solid, not constricting.

Yes, in the patient’s household at up to 60°C, gentle cycle recommended. Hotter than that damages the padding and changes how pressure is distributed on the sternum. Not suitable for hospital laundry.

No. It is a single-patient product under EU Medical Devices Regulation 2017/745, for hygiene and patient safety.

After open-heart surgery through the breastbone (median sternotomy), the PRO Support Vest. After surgery through the side of the chest, or for rib injury, the ThoraxBelt. For immediate universal-fit stabilisation including after TAVI, Chestfix. If in doubt, call us.

Vest size is not shirt size. Measure around the chest below the armpits, keeping the tape above the nipple line, then use the sizing guide. Between sizes, choose the smaller. Chestfix is universal fit and needs no measuring.

ThoraxBelt and Chestfix typically 5–7 working days. The PRO Support Vest typically 1–3 weeks, depending on order size and location. If surgery is imminent, call 1300 707 222 before ordering and we will tell you what is achievable.

Unopened vests still sealed in their vacuum pack can be exchanged within 30 days of purchase. Once the pack is opened the vest cannot be refunded or exchanged, for hygiene reasons — so measure carefully, or let us confirm your size first.

Many Australian patients claim it through extras cover and commonly receive $100 to $300 back, depending on the policy. Cover varies by fund, so check yours. A tax invoice comes with every order — see the rebate guide.

Yes. PRO vests are packaged five pieces per size per package, purchase orders are accepted from hospital accounts payable, and evaluation units are available for ward trials. See for hospitals.
