Although a continuous patient monitoring system has improved patient safety in ICUs, the effort for enhancing patient care and delivering excellent care begins with preventing ICU admissions.

Patient monitoring in low-acuity general hospital wards is now dependent largely on nursing staff's intermittent observations and measurements of the vital signs. In a fast-paced environment, timely detection of changes in vital signs may provide a critical early indication of potential health problems. Continuous wireless vital sign monitoring provides an effective and efficient means of patient vital sign monitoring in general care units.
