They are NOT mandatory —\nthey are only present when a matching ObservationDefinition exists.\n\nOnly Observations whose code matches the whitelist are synced:\n- 8310-5 (Body Temperature)\n- 59408-5 (SpO2)\n- 8867-4 (Heart Rate)\n- 9279-1 (Respiratory Rate)\n- 85354-9 (Blood Pressure)\n- 10000-F (Gait Group — custom LOINC)\n- 10100-F (Cognition Group — custom LOINC)\n- 20000-I (ECG+PCG Valvular Assessment — custom LOINC)\n- 3000-G (Frailty Physical Assessment -- custom LOINC)\n\nMedia and Device resources are stripped before sending to Glintt.",
