Carbon-Dioxide Enclosure Modulation D grade Plausibility · Plausible substrate (CO2 has real vascular effects); isolated evidence for the enclosure step is absentAtmosphere, Gas & Pressure Route ambientInvasiveness non-invasiveDirection additive
Modulated CO2 delivered only as one step of a chamber sequence; no isolated evidence for the CO2 step was located.
Origin & lineage
Multi-step chamber sequences (e.g. HOCATT).
Claimed mechanism
Elevated ambient CO2 is claimed to drive vasodilation / oxygen delivery within a chamber protocol.
Plausibility
Plausible substrate (CO2 has real vascular effects); isolated evidence for the enclosure step is absent.
Evidence — grade D
Delivered only as one step of a chamber sequence; no isolated evidence located for the CO2 modulation itself.
Market
Makers: HOCATT and similar.Models: Multi-modal chambers.Price: Clinic.
Kernel — keep vs set aside Keep — real substrate
CO2 has real vascular physiology.
Set aside — claim
No isolated evidence; the step cannot be evaluated apart from the chamber sequence.
