The Solar8000 relays the Primus's ventilation numbers¶
Solar8000 ETCO₂, RR_CO2, VENT_PIP and VENT_RR change only every 6–8 s: they are Primus values passed on through the Solar8000's 2 s polling, not measured by the monitor.
| Status | established: shown on many cases, with a control. |
| Devices | Solar8000 monitor, Primus anaesthesia machine |
What it means¶
These tracks carry the Primus's timing plus the relay, and duplicate the Primus's own numerics.

| 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. |
