Bronchial Provocation protocols Database
The response to a bronchoprovocator is usually assessed in terms of change in the
FEV1, vital capacity or airways resistance on the basis of serial measurements (FVC
manoeuvres) in which the results of the initial test constitute the reference values. The
international literature proposes several standardised protocols in order to address the
methodological issues of the various available techniques.
The possibility to store a bronchoprovocation protocol in a database is useful to simplify
and automate the sequence of operations that the Physician need to execute during the
bronchoprovocation tests.
The typical sequence of activities to carry out a bronchoprovocation test are:
1. Typing and storing a bronchoprovocation protocol in the database (usually only
once).
2. Selection of protocol among the list of the ones already present in the database
before carrying out the FVC post tests (the selection of “manual protocol” allows to
execute the test fully manually).
3. Performing the Post tests.
