If the new measurements are
within the limits appropriate for this patient (patient profiling),
the data is added to the individual's file on the server. But if the readings are identified as being of concern, the server will automatically notify the GP. The GP or Practice Nurse can access patient data on the remote server via a secure web page and get in touch with the asthma patient (by sending a text or placing a voice call to the xda). In addition, whenever no measurements have been received for more than a day, the server will auto send a text message to the xda requesting new data from the patient.  A doctor can access the data via the Internet for a view of the patient's records before a consultation.  The ability to also provide the data back to the patient on the xda provides an opportunity for improved self management as patients are enabled to understand their symptoms and take appropriate remedial action.
