See the HealthVault Data Type Wiki for current information on using this type.

This document contains general guidelines for using the PeakFlow data type. It does not cover all the information that is stored in the type – see the PeakFlow documentation for more information.

 

The PeakFlow data type is used to store peak flow measurements obtained as part of ongoing peak flow tracking.

A measurement can store values for pef, fev1, or fev6. In addition, there may be information useful to interpret the measurement (such as measurement context, notes about the measurement, etc.) in the MeasurementPlags property.

The Peak Flow data type is versioned on top of the previous Spirometry data type, which has been deprecated. Current data that was stored as Spirometry measuments may now be accessed as PeakFlow measurements.
