Solar8000 heart rate is truncated, not rounded¶
The Solar8000 heart rate drops its fraction (floor), in 24 of 24 pilot cases; the respiratory rate rounds.
| Status | established: shown on many cases, with a control. |
| Variables | Solar8000 heart rate |
What it means¶
A heart rate computed from R–R intervals reads about 0.7% higher unless it is truncated the same way.

| How the monitors compute their numbers | 2026-10-12 | current | Recomputing each monitor numeric from its own waveform finds a short, simple algorithm for every one (a median, an exponential average or a time mean over 3–30 s) and a delay of 2–9 s behind the newest data it uses. No value is stamped before its data exist. |
