Claim 0:
1. A system for monitoring a plurality of hospitalized patients, comprising:
a plurality of body-worn monitoring systems, wherein each body-worn monitoring system in the plurality of body-worn monitoring systems is uniquely associated with a patient in the plurality of hospitalized patients, and wherein each body-worn monitoring system in the plurality of body-worn monitoring systems comprises
a PPG sensor,
an ECG sensor,
at least two three-axis accelerometers configured to enable the modeling of motion, activity level, and arm height for the patient based on three time-dependent accelerometer waveforms from each three-axis accelerometer,
a microprocessor operably connected to each of the PPG sensor, the ECG sensor, and the at least two three-axis accelerometers to receive therefrom on a continuous basis a time-dependent photoplethysmogram waveform, a time-dependent ECG waveform, and three time-dependent accelerometer waveforms from each three-axis accelerometer, and determine therefrom on a continuous basis a heart rate value, a blood pressure value, an SpO2 value, and a motion parameter indicative of patient posture and motion, and to determine an alarm rule indicating whether or not the patient requires attention by collectively processing the heart rate value, the blood pressure value, the SpO2 value, and the motion parameter,
wherein each body-worn monitoring system in the plurality of body-worn monitoring systems is configured to communicate over a wireless network within the hospital;

a remote monitor operably connected to the plurality of body-worn monitoring systems via a network within a hospital configured to
for each of the patients in the plurality of hospitalized patients, receive on a continuous basis the heart rate value, the blood pressure value, the SpO2 value, the patient posture and motion for the corresponding patient, and the alarm rule,
in a first user-selectable view, display the heart rate value, the blood pressure value, the SpO2 value, an icon indicating patient posture and motion, and an icon indicating whether or not the patient requires attention based on the alarm rule for each of the patients in the plurality of hospitalized patients, and
in a second user-selectable view, display the heart rate value, the blood pressure value, the SpO2 value, an icon indicating patient posture and motion, an icon indicating whether or not the patient requires attention based on the alarm rule, and the time-dependent ECG waveform for a single patient in the plurality of hospitalized patients.
