Code Blue BMS Integration for Patient Room Environment Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current building management systems (BMS) in healthcare facilities lack the capability to automatically and efficiently respond to code blue events by adjusting environmental conditions such as temperature, pressure, and humidity in patient rooms, which can delay critical care and impact patient outcomes.
Innovation Solution
A BMS integration engine that processes nurse call information to identify code blue events and autonomously controls HVAC and lighting systems within patient rooms, adjusting environmental conditions to optimize the room environment for emergency responses without relying on off-premises processing, and also provides live video feeds and notifications to care teams.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a BMS integrates code blue detection and automatic environmental control, then response efficiency and patient care quality improve, but system complexity increases
Solution Approach 1:
The patent combines multiple previously separate functions (nurse call monitoring, code blue detection, HVAC control, lighting control, and video feed management) into a single integrated BMS platform. The integration engine consolidates these subsystems, allowing automatic coordination of environmental controls and notifications when a code blue event is detected, thereby improving response efficiency while managing system complexity through unified architecture.
Solution Approach 2:
The BMS is designed as a multi-functional system that not only monitors nurse calls and detects code blue events but also simultaneously controls HVAC systems, lighting systems, and video feeds. This universal platform performs diverse functions across different operational domains (monitoring, environmental control, communication), enabling comprehensive emergency response capabilities within a single system framework.
2Reliability
If automatic environmental adjustments are implemented during code blue events, then patient outcomes improve, but energy consumption increases
Solution Approach 1:
The system pre-configures optimal environmental parameters (temperature, humidity, air composition) for code blue scenarios. When a code blue event is detected, the integration engine immediately activates pre-programmed HVAC and lighting adjustments without requiring real-time calculation or manual intervention, enabling rapid response that improves patient outcomes while minimizing the duration of high-energy consumption states.
Solution Approach 2:
The BMS dynamically adjusts environmental parameters based on the specific code blue event detected. The system modifies temperature, pressure, humidity, and air composition in real-time according to the emergency situation, then returns to baseline conditions when the event resolves. This dynamic control ensures optimal patient care during emergencies while avoiding unnecessary energy consumption during normal operations.
3Loss of time
If on-premises processing is used for code blue events, then response time improves, but infrastructure requirements increase
Solution Approach 1:
The integration engine serves as an intermediary component that bridges the nurse call system, environmental controls, and notification systems. By positioning this mediation layer on-premises, the system enables rapid local processing of code blue events without requiring external cloud connectivity, reducing response time while managing infrastructure requirements through a focused intermediate processing layer rather than distributed complexity.

A building management system (BMS) of a building for controlling a healthcare facility. The BMS including one or more processing circuits comprising one or more memory devices configured to store instructions thereon that, when executed by one or more processors, cause the one or more processors to: receive a signal indicating a code blue event in a room for a patient; and adjust at least one of a temperature, a pressure, a humidity level, a lighting system, or an air composition in the room automatically in response to the received signal.
