Clinical & Research Utilities
These tools cover the practical arithmetic of hyperbaric oxygen therapy — unit conversion, course scheduling, cost estimation, and oxygen toxicity dose tracking. Each tool runs entirely in your browser; no data is uploaded or stored. Use them as references alongside your clinical judgement and facility protocols; they are not substitutes for physician-supervised calculation of individual treatment doses.
Pressure unit confusion is one of the most common sources of error when interpreting hyperbaric literature. The US clinical standard is ATA (atmospheres absolute), but trial reports frequently use psi, mmHg, or feet of seawater (fsw). The Pressure Converter provides instant conversion across all four units.
Standard neurological HBOT protocols run 40 sessions over 8 weeks, with specific scheduling considerations around weekends, interim assessments, and post-course follow-up. The 40-Session Course Planner generates a visual calendar from your start date, flagging key milestones.
Off-label HBOT (TBI, long COVID, stroke recovery, fibromyalgia) is typically out-of-pocket in the US. Per-session costs vary significantly by facility type, pressure, and region. The Course Cost Estimator provides a range for budget planning.
For extended-course or deep HBOT protocols, cumulative pulmonary oxygen toxicity becomes clinically relevant. The Oxygen Toxicity Calculator computes CPTD (Cumulative Pulmonary Toxic Dose) and UPTD (Unit Pulmonary Toxic Dose) for a course specification.
