A method of measuring features of a digitally generated waveform, comprising: synchronizing and transferring, by a data management system (60, 60'), patient data between multiple information systems in communication with a source of the patient data and a remote mobile device), the data management system (60, 60') configured to function as an intermediary between the remote mobile device and the multiple information systems and including a synchronization services module communicating with a synchronization database that stores patient data, said patient data being synchronized between the data management system and the multiple information systems, the data management system communicating patient data retrieved from the synchronization database to the mobile device that is remote from the source of the patient data; generating the waveform on a touch-screen display of the remote mobile device based on the patient data; measuring along an axis of the waveform, the measuring comprising: generating a first point (266, 268) corresponding to the waveform based on contact with the touch-screen display, generating a second point (266, 268) corresponding to the waveform based on contact with the touch-screen display, automatically measuring a distance between the first point and the second point along the axis upon generation of the second point, displaying a value corresponding to the distance on the touch-screen display; and transmitting the value to a patient information system located at a facility. synchronizing and transferring, by a data management system (60, 60'), patient data between multiple information systems in communication with a source of the patient data and a remote mobile device), the data management system (60, 60') configured to function as an intermediary between the remote mobile device and the multiple information systems and including a synchronization services module communicating with a synchronization database that stores patient data, said patient data being synchronized between the data management system and the multiple information systems, the data management system communicating patient data retrieved from the synchronization database to the mobile device that is remote from the source of the patient data; generating the waveform on a touch-screen display of the remote mobile device based on the patient data; measuring along an axis of the waveform, the measuring comprising: generating a first point (266, 268) corresponding to the waveform based on contact with the touch-screen display, generating a second point (266, 268) corresponding to the waveform based on contact with the touch-screen display, automatically measuring a distance between the first point and the second point along the axis upon generation of the second point, displaying a value corresponding to the distance on the touch-screen display; and generating a first point (266, 268) corresponding to the waveform based on contact with the touch-screen display, generating a second point (266, 268) corresponding to the waveform based on contact with the touch-screen display, automatically measuring a distance between the first point and the second point along the axis upon generation of the second point, displaying a value corresponding to the distance on the touch-screen display; and transmitting the value to a patient information system located at a facility.
