1. What is the Daily view?

Upon logging into Tidepool Web, you can access the Daily view by clicking on the "Daily" link in the header at the top of the page. 

The Daily view will display data from four types of devices:

1. Blood glucose monitors
2. CGMs
3. Insulin pumps
4. Notes that have been entered from Tidepool Web, Tidepool Mobile on iOS or Tidepool Mobile on Android

This view lets you see interactions between insulin delivery, carb ingestion, and blood glucose levels.

In the example above, you are seeing data from a Tandem t:slim X2, which includes data from a Dexcom G6 CGM. Regardless of your device, your data will look the same in Tidepool — although, we do things a little differently for Medtronic 670G insulin pump data and Tandem t:slim X2 pumps with Control-IQ Technology. 

2. Navigating dates and times

There are three ways to get to different dates or times: by date navigation, quick browsing, or time range.

Date navigation

You can go backward and forward in time by using the date navigation arrows in the header bar. The single arrows will move the date by a single day, and the arrow with the line will move you to the end of your data. 

Clicking the icon next to the currently displayed date allows you to pick a specific day by inputting a date in mm/dd/yyyy format or clicking on a date using the calendar and clicking on a day. Click Apply to navigate to the specific date.

Quick browsing

For faster browsing, you can adjust the visible range of data by using the scroll bar along the bottom of the view.

Time range

If you want to move the time range that is visible a few hours backward or forward, click anywhere in the background of the data field and drag towards the left or right. 

Please note: If you recently uploaded data to Tidepool and do not see your recent data, click "Refresh" in the lower left-hand corner of the page to reload your view.

3. Adding notes

You can create notes to add more context to your diabetes — notes can be about an event, food you ate, or a goal you set at your last visit with your clinician. The note will appear in the timeline next to the Add Note icon, along with notes you enter from Tidepool Mobile. You will also see any notes that have been added by those you have invited to view your data in this field. 

There are three ways to add notes:

1. Click the "New Note" button to the far left.
2. Click anywhere on the Notes bar to create a note at that time.
3. Add notes on Tidepool Mobile on iOS or Tidepool Mobile on Android. 

 

You can hover over a note to see what it says:    

 

You can click on notes to edit them, or to add a comment:

 

 

4. Blood glucose readings

On the left, you can see the scale for the blood glucose (BG) values.

 

CGM data, if present, will appear as a collection of tiny dots that form a line, color coded based on your blood glucose targets. The coloring also applies to the larger circles that represent blood glucose finger checks.

 

In the example above, the high blood glucose target has been set to 180 mg/dL (10 mmol/L) and the low target has been set to 70 mg/dL (3.9 mmol/L). These are the default blood glucose targets, but you can change your target ranges to different values if you prefer.

 

Values that are below 54 mg/dL (3 mmol/L) will be represented in dark red. 

 

Values between your low glucose target and 54 mg/dL (3 mmol/L) will be represented in light red.

 

Values within your blood glucose target range will be represented in green.

 

Values between your high glucose target and 250 mg/dL (13.9 mmol/L) will be represented in light purple. 

 

 

Using your mouse to hover over a portion of the CGM line will show you the CGM value at that time.

 

 

Likewise, hovering over a larger BG dot will show you the value, and more information about where the BG value originated.

A "Source: Linked" blood glucose indicates that the BG reading came directly from a BG meter device, because it was linked wirelessly to the pump. Example - Medtronic MiniMed 670G and Contour Next Link 2.4 Meter

 

In contrast, this is a "Source: Manual" BG reading, originated via manual entry into the pump's bolus calculator, or written into Apple Health by an app and uploaded using Tidepool Mobile on iOS.

 

 

Readings from a blood glucose meter uploaded to Tidepool Web via Tidepool Uploader that are NOT linked to an insulin pump will show their source as "Meter".

 

 

5. Boluses and carbohydrates

 

The scale, in units of insulin, is shown on the left. Along the x-axis (time) you can see all of the insulin delivered in bolus form. Using your mouse to hover over a bolus will show you more information in a bolus tooltip.

 

Here you can see a normal bolus that was created without using a bolus calculator. 

This tooltip shows a bolus calculator bolus with carbs included in the calculation. The carb count appears in a yellow circle above the bolus. The tooltip shows you information used in calculating the bolus including the BG, inputted carbs, Insulin on Board (IOB), Insulin to Carbohydrate Ratio (I:C), Insulin Sensitivity Factor (ISF), and Target BG.

 

 

If you are using Exchanges on your older Medtronic insulin pump, you will see an orange circle that displays the number of exchanges inputted as part of the bolus calculator.

 

Here is an extended bolus. Note the blue tail extending to the right of the bolus marker. Its height relative to the bolus bar indicates what % of the insulin was extended. The length of the tail indicates the duration of the extended portion of the bolus.  

 

 

Here is a bolus where the suggested insulin delivery was overridden. 

 

 

The solid line in the bolus represents the amount of insulin suggested by the pump's bolus calculator. The blue extending above that dark blue line indicates that more insulin was delivered than was suggested.

 

Here is a bolus where the suggested insulin delivery was underridden. 

 

 

Please note: The blue above the line will either be dark or light. Light indicates suggested delivery that was not delivered, whereas dark indicates insulin that was delivered over the amount suggested. 

 

An interrupted bolus will display a line similar to an overridden bolus. It will always be red to represent that the delivery of insulin was interrupted.

 

 

6. Basal Rates

The Basal Rates area shows the scale on the left in Units per hour. It displays an area shaded blue for delivered basal rates and uses a dotted line to represented scheduled basal rates that were not delivered due to a temporary basal rate. Using your mouse to hover over any of the areas will give you more information. 

Here you can see a basal rate that was delivered as scheduled:

Here is a temporary basal rate that is less than the scheduled amount, followed by the text you'll see when you hover: 

Finally, a pump suspension can be seen as follows: 

For insulin pumps with an automatic basal suspend feature like Basal-IQ or Medtronic's Predictive Low Blood Glucose Suspend (PLGS), your basal section will show flags for automatic basal suspensions indicating where they start (S), and when your normal basal rate resumes (R).

 

 

7. Aggregate statistics

Each statistic shows information about the 24-hour period shown in the Daily view fields above. If the stat is gray, this is due to a lack of necessary information to complete the statistic. The stats do change based on what 24-hour period is being displayed on the Daily view. For example: if you have the left edge of the Daily view start at 12 pm you will see stats for the 24 hours after that.

Time in Target Range widget

The Time In Target Range widget shows the percentage of the time that the user's blood glucose was below target (light red and dark red), in range (green), or above target (light purple and dark purple). This stat will take into account CGM data, as long as 75% of the total number of possible CGM readings in a day are present.

Blood glucose meter readings are taken into account so long as there are at least four readings in the twenty-four hour period.

Average Glucose widget

        

The Average Glucose is the average BG for that same 24-hour period from either a CGM or BGM, and one can choose which is displayed by using the toggle above the stats section on the top-right of the aggregate stats section.

Total Insulin widget

The Total Insulin widget shows how much basal insulin is delivered versus insulin taken as a bolus. In order for this stat to populate, the basal data must be continuous for the 24-hour period that is visible.

 

Total Carbs widget

The Total Carbs widget shows you the total amount of carbohydrates uploaded from an insulin pump or from carbohydrate data from Apple Health uploaded via Tidepool Mobile.
