Health inequality isn’t an abstract issue—it’s a measurable, life-or-death reality. Across the UK, the US, and beyond, millions of early deaths are linked to systemic gaps in healthcare. One of the most alarming contributors is hiding in plain sight: everyday medical devices that work better for some people than others.

Airquity is a powerful example of how creative design thinking and inclusive medical innovation can come together to challenge this imbalance. By reimagining a familiar, life-saving tool, Airquity shows how advertising, design, and technology can actively shape a fairer future for healthcare.

The Hidden Bias in Pulse Oximeters

Pulse oximeters are among the most widely used diagnostic tools in modern medicine. They estimate blood oxygen levels and play a critical role in diagnosing respiratory conditions.

The problem?
Traditional pulse oximeters have a fatal flaw for people with darker skin tones.

Why Conventional Oximeters Fall Short

• They use light absorption to estimate oxygen saturation.
• Melanin affects how light travels through the skin.
• In darker skin, readings can be overestimated by up to 7%.
• A difference of just 6–8% can decide whether a patient receives life-saving oxygen or is sent home untreated.

This technical limitation has contributed to suboptimal care and avoidable deaths, particularly among Black communities who already face structural disadvantages and deep mistrust in healthcare systems.

A Global Health Inequality That Can’t Be Ignored

Racial disparities in healthcare are not limited to one country or system.

• People of African and African-American descent are three times more likely to die from respiratory conditions than white patients.
• Medical devices have historically been designed, tested, and validated on Caucasian populations.
• Marginalised groups have been underrepresented in clinical trials for decades.

These inequalities highlight a harsh truth: healthcare technology has not been built for everyone.

The Creative Idea: Designing Around Bias, Not Through It

Rather than trying to “fix” the limitations of existing pulse oximeters, Airquity took a more radical—and creative—approach.

A Simple but Powerful Insight

There is one place on the human body where skin tone doesn’t vary in the same way:

The ear canal.

By shifting the measurement site away from the skin’s surface, designers identified an opportunity to bypass melanin-based bias entirely.

What Is Airquity?

Airquity is a non-invasive, core pulse oximeter designed to measure vital health metrics from the inner ear canal, where skin looks the same regardless of race.

Key Features

• Medical-grade accuracy
• Racially inclusive diagnostic readings
• Non-invasive biometric sensing
• Designed for real-world clinical use

Empowered by EarSwitch technology, Airquity reframes what equitable healthcare tools can look like—without compromising performance or usability.

Strategy & Insight: Challenging Systemic Design Failures

The strategy behind Airquity is rooted in a critical observation:

Health inequity is not only a social problem—it’s a design problem.

Medical tools shape clinical decisions. When those tools are biased, outcomes become biased too.

Airquity directly addresses:

• Survival inequity linked to inaccurate diagnostics
• Structural bias embedded in healthcare technology
• Trust gaps between marginalised communities and medical systems

By removing racial bias at the diagnostic level, Airquity creates a foundation for more equitable treatment outcomes.

Execution: Turning Medical Innovation into a Human Story

The Airquity campaign avoids cold, technical storytelling. Instead, it leans into emotion and human impact.

Campaign Highlights

• A product film presented in a consumer-style narrative
• Clear demonstration of real-world benefits
• Focus on patients, not just technology

This approach bridges the gap between complex medical innovation and public understanding—making the issue personal, urgent, and impossible to ignore.

Real-World Impact and Industry Recognition

Airquity’s innovation is already translating into tangible progress.

Key Results

• EarSwitch has been accepted into the Innovative Devices Access Pathway (IDAP), a programme accelerating life-saving technologies into the NHS.
• The scheme supports regulatory navigation, clinical validation, and faster patient access.
• In early 2025, the FDA released updated guidelines requiring greater racial inclusion in clinical testing, marking a major industry shift.

Airquity is positioning itself as the first racially agnostic pulse oximeter, with the potential to create equitable access to care for:

• 380 million people across the UK, USA, and Europe
• 3.5 billion people globally

Why Airquity Matters Beyond Healthcare

Airquity isn’t just a medical device—it’s a case study in purpose-driven innovation.

For creatives, marketers, and designers, it proves that:

• Inclusive design can save lives
• Creativity can challenge systemic injustice
• Advertising can amplify meaningful change

It’s a reminder that the most powerful campaigns don’t just sell products—they rewrite the rules.

Final Thoughts: Creativity That Saves Lives

Airquity stands at the intersection of design thinking, healthcare innovation, and social impact. By identifying a blind spot in medical technology and responding with a bold, human-centred solution, it sets a new benchmark for inclusive design.

In a world where health inequality has been normalised for too long, Airquity shows what happens when creativity refuses to accept the status quo—and chooses to design for everyone instead.

Airquity isn’t a new product story — it’s a design failure being exposed.
The campaign solves a hidden but critical problem: medical technology that claims to be “neutral” often works better for some bodies than others. Airquity reframes racial bias in healthcare as a design flaw, not a moral debate.

2. Why This Campaign Matters

Pulse oximeters are used millions of times every day, yet most people don’t know they can be inaccurate for darker skin tones.
Instead of shouting about inequality, this campaign makes the issue visible, measurable, and undeniable. It shifts the conversation from awareness to accountability — especially for an industry that relies on trust and precision.

3. What Most People Miss

This isn’t a diversity campaign — it’s a systems critique.
By focusing on data accuracy rather than identity, the work avoids defensiveness and guilt. The audience isn’t asked to “care more,” they’re shown that the system itself is broken. That’s why the message lands with clinicians, policymakers, and technologists alike.

4. Execution Choice That Made the Difference

The decision to centre the campaign around a functional object (the oximeter) rather than human stories was crucial.
No dramatization. No emotional testimonials. Just evidence-led design thinking. This restraint gives the campaign credibility — it feels closer to a scientific revelation than an advertising message.

5. Clear Takeaway

Great creative work doesn’t always add emotion — sometimes it removes noise.
When you expose a problem at the design level, you change behaviour faster than when you argue at the moral level.[/pms-restrict]
