BREATHE Program · Hospitals

Protecting the patients who can least afford to get sick.

HAIQU is deploying CRISPR-powered biosensors and digital twin risk modeling in hospital emergency departments — the highest-stakes air environments in American healthcare.

Led by Mayo Clinic · ARPA-H BREATHE Program

The Challenge

Hospital emergency departments are simultaneously the most crowded and the most medically vulnerable air environments in America.

Emergency departments bring together people in acute distress, immunocompromised patients, elderly individuals, and clinical staff — in spaces with high patient turnover, continuous exposure, and air shared across everyone in the room.

Hospital-acquired respiratory exposures represent a serious risk for patients who are already vulnerable. Yet the air in most EDs is managed for thermal comfort, not health outcomes.

HAIQU is building the infrastructure to change that — giving hospital buildings the ability to see what's in their air and act on it automatically.

Immunocompromised patients face the highest risk

Patients undergoing cancer treatment, organ transplant recipients, and others with compromised immune function are at severe risk from airborne exposures in shared clinical spaces.

COPD affects 16 million Americans

Including millions more who are undiagnosed. Airborne exposures in healthcare settings can trigger acute exacerbations with serious consequences.

The Approach

CRISPR biosensors. Digital twins. Real-time protection.

Microfluidic CRISPR biosensor

A biosensor based on microfluidic droplet CRISPR technology — enabling rapid, highly sensitive detection of specific airborne organisms without the delays of traditional laboratory analysis.

Agent-based & digital twin modeling

Advanced modeling techniques — including agent-based simulation and digital twin representations of hospital spaces — translate what's in the air into quantitative, patient-specific risk estimates in real time.

ED field trials across three states

HAIQU is validating its platform through field trials in emergency departments across Mayo Clinic's network — testing in diverse clinical environments across multiple U.S. climate zones.

Field trials across Mayo Clinic's three campuses

Minnesota

Mayo Clinic — Rochester, MN. Mayo Clinic's flagship campus, the largest integrated medical group practice in the world.

Arizona

Mayo Clinic — Phoenix/Scottsdale, AZ. Testing in a high-heat, low-humidity climate zone.

Florida

Mayo Clinic — Jacksonville, FL. Testing in a humid subtropical climate zone with year-round allergen and mold exposure.
