摘要:
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.

There is provided an apparatus (12) for use with a wearable cuff (14) in determining blood pressure and/or pulse rate. The wearable cuff (14) is inflatable to pressurize a measurement site of a subject (18). The apparatus (12) is configured to acquire a pressure signal indicative of pressure in the wearable cuff (14) during inflation of the wearable cuff (14) to pressurize the measurement site of the subject (18) and analyze the acquired pressure signal to detect an artifact corresponding to a decrease in pressure during inflation of the wearable cuff (14) due to cuff slippage. The apparatus (12) is also configured to determine the blood pressure and/or pulse rate of the subject (18) by analyzing oscillations in the acquired pressure signal, wherein determining comprises compensating for the detected artifact.

A method includes generating at least first and second histograms respectively for at least first and second sets of vital sign measurements using at least first and second predetermined bins. The first and second sets of the vital sign measurements each include at least two measurements acquired at different times, and the first and second vital sign are different vital signs. The method further includes generating a first score distribution for the first vital sign by mapping each bin of the first predetermined bins to a corresponding predetermined score. The method further includes generating a second score distribution for the second vital sign by mapping each bin of the second predetermined bins to a corresponding predetermined score. The method further includes generating a compound score distribution for the first and second vital signs based on the first and second score distributions, the compound score distribution indicates a patient's health state.

There is provided a context detection apparatus for use with a medical monitoring device arranged to measure a physiological characteristic of a subject. The context detection apparatus comprises at least one context sensor comprising a camera; and a processing unit. The processing unit is arranged to receive image data acquired by the camera from the at least one context sensor; analyze the received image data to generate a plurality of different types of context information; wherein each type of context information comprises information which relates to a factor capable of influencing measured values of the physiological characteristic and which is not measurable by the medical monitoring device; and output a signal to the medical monitoring device based on the generated context information. The processing unit is arranged to analyze the received image data by detecting features in the received image data; and classifying each detected feature as relating to a particular one of the plurality of types of context information.
