Medical innovation begins with a plausible hypothesis and becomes valuable through well-designed studies. We show what mechanism data, preclinical findings and external clinical signals already support, then define the next measurable validation step. Evidence boundary: AIRCHILL has treated 0 patients. Early feasibility work included healthy volunteers and preclinical models. These data can justify further clinical validation, but they do not prove patient efficacy. Research questions ## Where earlier neuroprotection could matter. Our current planning covers several time-critical indications. The effect scenarios are transparent sensitivity analyses, not claims of AIRCHILL efficacy. ### Cardiac arrest Earlier temperature control, neuroprotection, timing, safety and neurologically favourable survival. ### Stroke Neuroprotection around thrombectomy and the question whether an additional early intervention can improve functional outcome. ### Neonatal HIE Established therapeutic hypothermia provides a strong biological precedent; any new transport or early-cooling approach requires separate paediatric validation. ### Traumatic brain injury Population selection, intracranial pressure, timing, duration, rewarming and clinically relevant outcomes. ### Heatstroke Cooling speed is critical. A future respiratory approach would need to be evaluated as a complementary option, not as a replacement for established rapid cooling. ### Concussion A separate research field with external head/neck cooling signals; typical concussion is not a current respiratory AIRCHILL use case.

[GitHub organisation →](https://github.com/EthicalSaving-gUG) Emergency care reform 2026 ## A controlled evaluation and reimbursement pathway for prehospital innovation. Our current proposal would open the existing German evidence-generation pathway under §137e SGB V to emergency medical services and add a temporary, transport-independent trial reimbursement route under §133 SGB V.
