Known changes.
Explainable responses.
A synthetic experiment inspired by NASA’s proposal for AI medical support: introduce a known change, observe the response and compare it with a predefined expectation. These readings never enter the crew’s mission records.
Read the NASA research proposal ↗Expected: Three higher pulse readings after six earlier readings. Expected: ask whether activity has ended; do not infer symptoms.
Detector result: Matches the predefined expectation · pulse-rise

What it could mean
Your pulse is higher than earlier in this session. Activity could contribute, but you have not confirmed any exercise yet.
Still unknown: These readings do not identify a diagnosis or tell us how you feel.
What to do now
Why NASA context matters
NASA describes exercise as a countermeasure for the effects of altered gravity.

Readings, sources & explanation details
This is why ZENIT asks about activity when pulse changes. It does not prove that exercise caused this change.
Heart rate: 75 → 105 bpm. Sustained change in this demo.
Breathing rate: 14 → 14 /min. No sustained change under demo rules.
SpO₂: 98.0 → 98.0 %. No sustained change under demo rules.
Skin temperature change: 0.1 → 0.1 °C. No sustained change under demo rules.
The values above are medians: the middle value of six earlier readings compared with the middle value of three recent readings. They come from the same device and mission phase, over no more than five minutes. They are not your long-term clinical baseline.
Demo triggers: pulse +20 bpm, breathing +4/min, SpO₂ −2 percentage points, skin change +0.4 °C; suit CO₂ +0.15 kPa, O₂ ±1 kPa, pressure ±0.5 kPa or air temperature ±2 °C. These are presentation rules, not NASA medical limits.

NASA resources explain the monitoring context. They do not validate this algorithm or its interpretations. Historical RadLab measurements are not used to infer the cause of your symptoms.
