• Extra Large
• 2X/3X Large

Standard sizing provides a simpler ordering and stock system. But it may not suit all body shapes optimally.

Custom Sizing

Some gowns come in expanded size options for better fit:

• Numerical sizes like 32, 34, 36, etc.
• Short, regular and tall lengths

Custom sizing improves coverage and mobility but complicates inventory management with more SKUs.

One Size Options

“One size fits most” gowns cater to a wide range of body types. Benefits include:

• Fewer gown options to purchase and stock
• Often feature adjustable/expandable components
• Suitable for visitors who need temporary gowns

One size gowns provide less tailored fit for healthcare personnel though.

Accommodation Using Adjustable Features

Most gown sizes tie or close in ways that enable some size adaptability. Tailoring fit to the individual wearer is key for optimal protection.

With many sizing and adjustment choices available, facilities can outfit personnel with well-fitting isolation apparel.

Care and Maintenance Considerations

To maintain protective performance over time, isolation gowns require proper care and handling. This applies to both disposable and reusable options.

Disposable Isolation Gowns

For disposables, considerations include:

• Avoid excessive folding or crumpling during storage
• Store in a cool, dry place and avoid direct sunlight
• Inspect packaging and gowns periodically for damage
• Follow manufacturer expiration dates for gown stock
• Discard used gowns promptly in designated hazardous waste

Reusable Isolation Gowns

Caring for reusable gowns requires:

• Checking for staining/damage before washing
• laundering separately with proper disinfectant
• Ensuring thorough drying to prevent mildew
• Mending or removing from service if damaged
• Following number of safe reuses recommended

Workplace Handling

In the healthcare setting:

• Stock gowns in and dispense from a clean, dry area
• Prevent contamination of unused stock during storage
• Remove visibly soiled gowns from circulation immediately

Proper care, maintenance, and handling preserves the protective qualities and lifespan of both disposable and reusable isolation gowns.

The Bottom Line

While just one piece of PPE, isolation gowns provide an essential safeguard. Paying attention to gown specifications, quality, and care helps ensure this critical protective barrier remains intact.

Innovations in Isolation Gown Design

As medical apparel technology evolves, new isolation gown designs continue emerging to better protect healthcare personnel. Key innovations aim to enhance barrier effectiveness, improve comfort and use, and address environmental concerns.

Advanced Materials

New gown fabrics and composites include:

• Nanofiber spunbond nonwovens for superior liquid resistance
• Bio-based materials like PLA from renewable sources
• Graphene laminates with exceptional bacterial filtration

These enhance protective qualities while reducing environmental impact.

Strategic Reinforcements

Selectively reinforcing specific zones optimizes gown performance:

• Coated chest panels for maximal fluid protection
• Reinforced hems, seams, and knit cuffs
• Moisture-wicking inner cuff layers

Targeted reinforcements focus protective features where needed most.

Improved Fit and Mobility

New designs provide better freedom of movement:

• Articulated elbows and shoulders
• Athletic-inspired fabrics with 4-way stretch
• Knit fabric waistbands for flexibility

These ergonomic elements help reduce fatigue and improve clinical workflows.

Sustainability

Eco-conscious innovations include:

• Biodegradable and recyclable materials
• Reusable/reprocessable gown models
• Zero-waste manufacturing methods

New isolation gowns protect people and the planet for a better future.
