Ambulatory physiological monitoring with remote analysis
InactiveUS20120259233A1Fast response timeSave livesElectrocardiographyTelemedicineData streamCardiac cycle
Applicants have disclosed a wireless method for remotely monitoring the physiological status of ambulatory patients by using at least one “cloud” server. Physiological data, including ECG data, is collected by a device worn by a patient and then wirelessly transmitted (e.g., via a cell phone) to the server(s). Remote processing of electrocardiograms (“ECG”) is achieved, in part, by data streaming packet lengths acquired over no less than 3 seconds—3 seconds is typically equivalent to about 3 cardiac cycles (heartbeats)—to provide the quickest response time by clinicians to try to save a heart patient's life. Other types of physiological data are monitored by the device, so medical help can be obtained when needed. In this manner, any sudden onset of vicissitudes in a patient's well being may be detected and transmitted to the care-giver and patient in near real-time.
