Heart Rate Variability Analysis As A Means Of Real-Time Hypercapnia Detection, Joseph Dituri

USF Tampa Graduate Theses and Dissertations

The motivation for this research is the high prevalence experienced by divers of carbon dioxide (CO₂) issues and concerns throughout their lives. Additionally, CO₂ is naturally occurring, the product of oxidative metabolism, and is undetectable to human senses. Current CO₂ sensor or detection technology is limited to high-cost machines such as arterial blood gas monitors and end tidal CO₂ monitors, or more modern technology relying upon bright lights which measure blood flow. The light technology is notoriously unreliable and does not produce a very effective heart beat allowing a user to detect minimal changes. Heart …
