Josef David is the owner of RapidKnowHow® — THE DECISION COMPANY™. RapidKnowHow® develops strategic algorithms for breakthrough decisions: repeatable questions, comparisons, decisions and verification that turn one critical business problem into one clear strategy, three actions and a measurable result. The approach combines industrial experience, proprietary decision systems and AI-assisted analysis. Leaders and their teams own the decision, implementation and evidence of value.
Medical gases become therapeutic tools only when gas identity, purity, dose, delivery and patient response are controlled. Oxygen, medical air and nitrous oxide explained as one clinical gas system.
Exercise raises oxygen demand and carbon-dioxide production. Human performance depends on matching oxygen delivery, circulation, ventilation and CO₂ removal to workload.
Altitude and cabin pressure can reduce oxygen partial pressure and degrade cognition, coordination and decision quality before the pilot fully recognizes the problem.
A RapidKnowHow® PowerPost series on how oxygen, nitrogen, helium, CO₂ and other gases influence human performance across diving, altitude, aviation, sport, industry, medicine and closed environments.
At altitude, oxygen still makes up about 21% of the air — but lower atmospheric pressure reduces oxygen partial pressure and can degrade human judgment, coordination and endurance.
A diver’s well-being depends not only on which gases are breathed, but on how depth and pressure change their effects. Oxygen, nitrogen, helium, nitrox and CO₂ explained as one operating system.
