1. A medical system comprising:
- at least one sensor configured to measure at least one of an activity state and a posture of a patient;
at least one vital sign sensor separate from the at least one sensor and configured to measure one or more vital signs of the patient according to a schedule wherein the one or more vital signs comprise one or more of pulse, oxygen saturation (SpO2), respiration, temperature, and carbon dioxide;
at least one processor programmed to;
adjust the schedule when the measured one or more vital signs is outside of a vital sign threshold;
control the at least one vital sign sensor to measure the at least one vital sign according to the adjusted schedule including delaying a scheduled measurement until the activity state indicates a resting state that is below the position threshold;
generate a patient deterioration alert when (i) the measured at least one of activity state and posture of the patient and (ii) the measured one or more vital signs are each outside of respective alarm thresholds; and
output the patient deterioration alert to an audio device.

Abstract
A method, and corresponding system (300), for monitoring patients based on activity state and posture. Activity state and/or posture of a patient are measured. Further, one or more vital signs of the patient are measured according to a schedule. Based on the measured activity state and/or posture of the patient and the measured one or more vital signs, the schedule is adjusted and/or patient deterioration is monitored for.

11. A medical method comprising:
-
with a first sensor, measuring at least one of an activity state and a posture of a patient; with a second, separate sensor, measuring one or more vital signs of the patient according to a schedule; with at least one electronic processor, controlling the first and second sensors to continue the measuring operations when (i) the measured at least one of activity state and posture of the patient is inside of a position threshold and (ii) the measured one or more vital signs is inside of a vital sign threshold; with at least one electronic processor, adjusting the schedule when the measured one or more vital signs is outside of a vital sign threshold; with the at least one processor, controlling the second sensor to measure the one or more vital signs according to the adjusted schedule; with the at least one processor, generating a patient deterioration alert when (i) the measured at least one of activity state and posture of the patient and (ii) the measured one or more vital signs are both outside of an alarm threshold; and with the at least one processor, outputting the patient deterioration alert to an audio device. - View Dependent Claims (12, 13, 14, 15, 16, 17)
