Abstract

Disclosed herein is a framework for facilitating adaptive control of monitoring devices. In accordance with one aspect, a position detector detects a chest elevation level and provides chest elevation level data. A processor uses the chest elevation level data to determine a heart elevation level with respect to a reference level. A comparator compares the determined heart elevation level with an elevation level of a monitoring device with respect to the reference level. In response to the comparison, a movement system adjusts the elevation level of the monitoring device.

Claims

6. The system according to claim 5, wherein the different demographic characteristics comprise age, height, weight, pregnancy status or gender.

7. The system according to claim 4, wherein the processor adjusts the predetermined factor by a predetermined coefficient based at least in part on body size of the subject to compensate for movement of the subject.

8. The system according to claim 1, wherein the movement system adjusts the elevation level of the monitoring device to match the determined heart elevation level.

9. The system according to claim 1, wherein the monitoring device comprises a blood pressure monitor.
