We are witnessing an explosive growth in medical devices that use wireless technologies. Some devices are implanted and some are worn on the body to control bodily functions and to measure an array of physiological parameters. The data from these sensors and monitoring equipment, together with patient observations of daily living, can be transmitted wirelessly to another location for review by relevant specialists.
Mobile devices allow for remote management of patients with a range of chronic diseases or patients recovering at home. Mobile medical applications are also transforming healthcare. Examples include apps that measure heart rate and blood pressure, perform an ECG, manage the delivery of insulin, take patient-specific information and provide a clinician with radiation dosage calculations, and allow doctors to view X-rays or other imaging on smart phones and tablets.
