Respiratory Diagnostics
DATA-LOGGING
BREATH ANALYZER
A portable, mixed-signal system that measures exhaled breath gases and airflow simultaneously, detecting respiratory problems before symptoms appear.
Explore Early AccessA GLOBAL RESPIRATORY CRISIS
Over 544 million people worldwide suffer from chronic respiratory disease, a 39.8% increase since 1990. Environmental pollutants are now outpacing infectious disease as the primary cause.
Current diagnostics rely on separate, expensive instruments, capnography for CO2, spirometry for airflow, each producing isolated data sets that a specialist must interpret collectively. This fragmented approach is slow, costly, and inaccessible for routine screening.
Critically, testing is typically performed only after symptoms become severe. By then, pulmonary damage may already be irreversible. Research consistently shows that early detection dramatically improves long-term outcomes.

ONE DEVICE.
EVERY BREATH BIOMARKER.
The BSI Data-Logging Breath Analyzer (DLSIB) replaces fragmented diagnostics with a single portable instrument. It measures O2, CO2, NO, mass airflow, temperature, and humidity simultaneously, producing a synergistic view of respiratory function that isolated tests cannot provide.
Built around a mixed-signal data-logging architecture with specialized potentiostat and transimpedance amplifier circuitry for electrochemical gas sensors, the system delivers laboratory-grade precision in a field-portable form factor. Every recording is time-stamped and exportable.

THREE STEPS TO INSIGHT
No specialized training or technician required. The system is designed for field deployment, clinical vitals, and research environments alike.
Collect
Subject breathes into a gas sample bag through a mask or mouthpiece. Takes only moments to capture a representative breath sample.
Analyze
Connect the sample bag to the DLSIB unit. The system simultaneously measures all gas concentrations and flow parameters, logging every data point with timestamps.
Interpret
View synchronized, multi-parameter strip charts via USB or wireless connection. Export CSV data for deeper analysis or integration with existing clinical workflows.
WHERE EARLY DETECTION MATTERS MOST
We are focused on early-access partners in the following fields, especially groups interested in real-world data generation and applied deployment.
Sports Performance & Kinesiology
Track respiratory efficiency during training cycles. Correlate breath gas ratios with exertion levels, recovery states, and metabolic thresholds, all from a portable device at the sideline or in the lab.
Veterinary Diagnostics
Developed in collaboration with the Texas Tech School of Veterinary Medicine for equine respiratory assessment. The non-invasive approach replaces or supplements bronchoalveolar lavage, reducing animal stress and accelerating diagnosis in the field.
Clinical & Environmental Research
Study the respiratory impact of air quality, occupational exposures, or therapeutic interventions with a device that captures all relevant biomarkers in a single session. Ideal for longitudinal studies requiring consistent, repeatable measurements.
WHY SIMULTANEOUS MATTERS
Breath biomarkers are deeply interrelated. Measuring them in isolation discards the correlations that matter most for early detection.
