Your app can record blood pressure data by writing to the com.google.blood_pressure
data type. In this data type, each data point represents a single instantaneous
blood pressure reading. The data point contains fields for the systolic and
diastolic pressure, body position during the reading, and location on the body
where the measurement was performed.
The systolic and diastolic fields are required, all others are optional.
Pressures for systolic (upper number) and diastolic (lower number) are
measured in mmHg.
If specified, body position must have one of the following values:
1 - standing up
2 - sitting down
3 - lying down
4 - semi-reclined
If specified, measurement location must have one of the following values:
1 - left wrist
2 - right wrist
3 - left upper arm
4 - right upper arm

To write a blood pressure data point, create a new DataSource
of TYPE_BLOOD_PRESSURE,
as shown in the following example.
If your data source was created successfully, you'll get a 200 OK HTTP
response status code. The response body contains a JSON representation of
the data source, including a datasource.dataStreamId property. Use this ID
as the dataSourceId to add data.
