This page shows an end-to-end example of wearable-based peri-operative vital sign monitoring in ENRICH-mHealth, using the ISiK Vitalparameter observation profiles together with the HDDT-derived Personal Health Device profile.
A 45-year-old male patient is scheduled for an orthotopic liver transplantation. To capture his physiological baseline and his post-operative recovery outside the hospital, he is equipped with a Withings ScanWatch 2 and monitored for two weeks before and two weeks after the transplantation (surgery on 2026-03-02).
Throughout both periods the wearable records arterial oxygen saturation (SpO2) and heart rate every 6 hours (four measurements per day). The pre-operative series documents a stable baseline; the post-operative series shows the expected recovery trend — a transiently reduced SpO2 that normalises and an initially elevated heart rate that settles over the two weeks.
Every measurement is captured as an Observation that references the wearable via Observation.device, so each value carries explicit device provenance back to the registered Personal Health Device.
| Device | Withings ScanWatch 2 (Personal Health Device) |
| Parameters | SpO2 (profile), heart rate (profile) |
| Sampling interval | every 6 hours (4× / day) |
| Pre-op window | 2026-02-16 … 2026-03-01 (56 timepoints) |
| Post-op window | 2026-03-03 … 2026-03-16 (56 timepoints) |
| Total observations | 56 × 2 periods × 2 parameters = 224 |
The full series is named Example-ENRICH-{SpO2\|HR}-LiverTx-{Pre\|Post}-01 … -56; all 224 instances are listed under FHIR Artifacts.
