🔹 Why It Matters
Infection Control: Prevents airborne contaminants from leaking into clean zones.
Patient & Staff Safety: Maintains correct airflow direction in critical areas like ICUs, operating rooms, and isolation rooms.
Real-Time Assurance: Provides instant visibility and alarms if pressure integrity is lost.

🔹 What ASHRAE Says
According to ASHRAE Standard 170 – Ventilation of Health Care Facilities, critical rooms must maintain defined pressure relationships:

Positive Pressure – Operating theaters, protective environment rooms.
Negative Pressure – Airborne infection isolation rooms.

The standard requires continuous differential pressure indication so staff can easily verify compliance and ensure safety.

🔹 Beyond Standards
When integrated with Building Management Systems (BMS), pressure monitors become powerful tools for facility teams—supporting accreditation, regulatory compliance, and long-term infection control strategies.

In short, room pressure monitors are not optional—they are guardians of healthcare safety, compliance, and trust
