Use-Case: Add Reading

1 Brief Description

When a glucose sensor

Makes a glucose reading

The reading is logged

So that patients and physicians can later review patient history, and an alert can be generated if

necessary

2 Actor Brief Descriptions

2.1 Glucose Sensor – the monitoring device that makes the reading

3 Preconditions

The glucose monitoring app has generated an alert.

4 Normal Flow of Events

The use case begins when the glucose monitoring device sends a glucose reading to the

smartphone.

1. The system adds the reading to the patient’s local history

2. The system buffers the reading for later transmission.

3. The use case ends

5 Alternative Flows

5.1 The glucose reading generates an alert

If after step 2 of the normal flow the reading satisfies an alert condition:

2.2 The system creates an Alert for the current glucose reading.

2.3 The system buffers the Alert for later transmission to medical staff.

2.4 The system triggers immediate transmission of buffered data.

2.5 The ‘Patient View/Respond to Alert’ use case is invoked.

The normal flow is rejoined at step 3

6 Key Scenarios

6.1 The glucose reading is within normal levels

6.2 The glucose reading is outside normal levels

7 Post-conditions

7.1 The glucose reading is buffered locally for later transmission

7.2 The glucose reading is buffered locally for transmission, an alert is buffered locally

for transmission, transmission has been triggered, and a patient alert has been

generated
