Checklist for CGM Implementation

(Key:

  • [x] available in data protocol/documented in spec and implemented
  • [-] available in data protocol/documented in spec but not yet implemented
  • [?] unknown whether available in data protocol/documented in spec; not yet implemented
  • *[ ] TODO: needs implementation!
  • [ ] unavailable in data protocol and/or not documented in spec and not yet implemented)

Required if Present

CBG

  • [x] cbg values
  • [ ] units of cbg values (read from device, not hard-coded)
  • [x] out-of-range values (LO or HI)
  • [x] out-of-range value thresholds (e.g., often 40 for low and 400 for high on CGMs)

Device-specific? (Add any device-specific notes/additions here.)

A status flag indicates if glucose reading was in response to calibration, which we store in payload with {calibration_response : true}.

Device Events

  • [x] calibrations
    • [x] calibration value
    • [ ] units of calibration value (read from device, not hard-coded)
  • [ ] time changes (presence of which is also in the BtUTC section below)
    • [ ] device display time from (before change) and to (result of change)
    • [ ] agent of change (automatic or manual)
    • [ ] timezone
    • [ ] reason for change (read from device)

Device-specific? (Add any device-specific notes/additions here.)

Calibration events contain three additional timestamps (timestamp, current_time and calibration_timestamp) as well as a calibration_reading (which should match the manual SMBG value), which we store in payload.

Settings

  • [ ] units preference for BG display
  • [ ] units of data being uploaded (will be mutated to mmol/L storage units if not mmol/L)
  • [-] transmitter ID
  • [-] low alert settings
    • [-] enabled
    • [-] level/threshold
    • [-] snooze threshold
  • [-] high alert settings
    • [-] enabled
    • [-] level/threshold
    • [-] snooze threshold
  • [-] rate-of-change alerts
    • [-] fall rate alert
      • [-] enabled
      • [-] rate threshold for alerting
    • [-] rise rate alert
      • [-] enabled
      • [-] rate threshold for alerting
  • [-] out-of-range alerts
    • [-] enabled
    • [-] threshold
    • [ ] snooze time between alerts
  • [ ] predictive alerts
    • [ ] low prediction
      • [ ] enabled
      • [ ] time sensitivity (minutes to predicted low for alerting)
    • [ ] high prediction
      • [ ] enabled
      • [ ] time sensitivity (minutes to predicted high for alerting)
  • [ ] calibration alerts/reminders
    • [ ] pre-reminder
    • [ ] overdue alert

Settings history:

  • [ ] device stores all changes to settings OR
  • [ ] device only returns current settings at time of upload

No Tidepool data model (yet): volume and/or vibrate mode of all alerts (can/should go in payload).

Device-specific? (Add any device-specific notes/additions here.)

"Bootstrapping" to UTC

  • [x] index
    • [ ] UTC timestamp (Hey, one can dream!) OR
    • [x] internal timestamp or persistent log index (across device communication sessions) to order all pump events (regardless of type), independent of device display time OR
    • [ ] ephemeral log index (does not persist across device communication sessions) to order all pump events (regardless of type), independent of device display time
  • [x] date & time settings changes

Device-specific? (Add any device-specific notes/additions here.)

No Tidepool Data Model Yet

NB: You can and should add to this section if there are other data types documented in the device's data protocol specification but not part of Tidepool's data model (yet).

  • [ ] activity/exercise
  • [ ] food (e.g., Dexcom allows logging carb events)
  • [ ] notes/other events

Tidepool ingestion API

Choose one of the following:

  • [x] legacy "jellyfish" ingestion API
  • [ ] platform ingestion API

Known implementation issues/TODOs

Use this space to describe device-specific known issues or implementation TODOs not contained in the above datatype-specific sections.
