Topic: Observation create or update?

Question about observations generated by a medical device: They may appear at high frequency, e. g. from a ventilator that provides tidal volume for each breath, or a pulse oximeter measuring SpO2 and heart rate continuously. What is the right approach for sending these observations to a server - POST a new observation for each updated value or create it once and update (with changed effectiveDateTime and value) by PUT or PATCH?

Each value is a distinct Observation. If you're doing trending, you'll need all of them, not just the most recent. You do have the ability to use the SampledData data type to capture multiple values in a single Observation (e.g. 1 minute's worth, 5 minute's worth, 1 hour's worth, etc.)
