The Patient Safety Problem
1. Overcrowded hospitals increasingly place critical patients in hallway beds and overflow areas where traditional nurse call systems do not exist.
​
2. These patients are forced to rely on verbal cries for help. When those calls go unanswered, patients fall, decompensate, or experience worsening outcomes.
​
3. Delayed response times are a patient safety risk—not a workflow inconvenience.
The Solution
​​​
​PulseLight Wireless is a portable, patient-initiated call-light system designed specifically for hallway and overflow care.
​
Patients request help using a physical button or voice.
AI interprets the request and activates a highly visible bedside light and staff alert that remains active until a caregiver responds at the bedside.
​
Why?
Emergency departments increasingly place critical patients in hallway beds and overflow areas where traditional nurse call systems do not exist. The system improves visibility, accountability, and response time without diagnosing conditions or providing clinical decision support.

HOW IT WORKS
Wireless call lights address critical gaps in traditional hospital communication systems, offering significant improvements in patient care and operational efficiency:
Patient Requests Help
The alert clears only after a caregiver responds at the patient’s location.
AI Interprets Intent
Lightweight AI identifies the type of assistance requested (e.g., help, pain, bathroom) for workflow routing only.
Button press or voice command
A highly visible hallway light and staff alert activates and remains on until addressed.
Staff Responds at Bedside
A highly visible hallway light and staff alert activates and remains on until addressed.

Staff Visibility Platform
Real-Time Awareness for Faster, Safer Response
​
Designed for hallway beds, overflow areas, and high-traffic units, the platform ensures no patient request goes unseen.
Pulse Light Wireless includes a staff-facing visibility platform that gives care teams immediate awareness of patient requests—without requiring additional hardware, complex training, or workflow disruption.
CURRENT STATUS
• Working prototype
• Pilot preparation underway
• Patent filed, including AI-enabled continuation
• Designed and led by an ER nurse
About the Founder
Founded by a frontline ER nurse
PulseLight Wireless was founded by an emergency room nurse with firsthand experience caring for critically ill patients placed in hallway beds without reliable call systems. The product was built in response to repeated patient safety failures caused by delayed response times and lack of communication in overflow care environments. This clinical perspective drives a focus on safety, usability, and real-world hospital workflows.
