Abstract
Technologies and implementations for a wearable healthcare system, which may be worn by a person. The wearable healthcare systems may include one or more motion sensors. A motion analysis modules may be included in the wearable healthcare system, which may be configured to determine physical activities and intensity of the physical activities of the person.
Claims23
A wearable cardioverter defibrillator (WCD) system comprising:
- a support structure, the support structure configured to be worn by a person;
- a motion sensor coupled to the support structure;
- and
- a motion analysis module (MAM) communicatively coupled with the motion sensor, the MAM configured to:
- receive data from the motion sensor,
- determine if the person is walking from the received data,
- responsive to the determination that the person is walking, determine a number of steps,
- calculate, based on a determined number of steps, a steps/minute value, a steps/6 minutes value, and a total daily steps value,
- determine a trend based at least in part on the steps/minute value, the steps/6 minutes value, and the total daily steps value, wherein the trend is indicative of a change in a health condition of the person,
- calculate a wellness parameter based on the trend, and output a recommendation for the person based on the wellness parameter, wherein the recommendation includes at least one of a recommended activity or activity level.
A method for determining a walking intensity of a person wearing a wearable cardioverter defibrillator (WCD), the method comprising:
- receiving a y-axis accelerometer signal from a motion sensor;
- determining whether the person is walking at least in part from the received y-axis accelerometer signal;
- responsive to the determination that the person is walking, determining a number of steps;
- calculating, based on a determined number of steps, a steps/minute value, a steps/6 minutes value, and a total daily steps value;
- determining a trend based at least in part on the steps/minute value, the steps/6 minutes value, and the total daily steps value, wherein the trend is indicative of a change in a health condition of the person,
- calculating a wellness parameter based on trend, and
- outputting a recommendation for the person based on the wellness parameter, wherein the recommendation includes at least one of a recommended activity or activity level.
A method for monitoring a health condition of a person wearing a wearable cardioverter defibrillator (WCD), the method comprising:
- measuring a steps/minute taken by the person based, at least in part, on a detected motion of the WCD;
- measuring a steps/6 minutes taken by the person based, at least in part, on the detected motion of the WCD;
- counting a daily total of steps taken by the person based, at least in part, on the detected motion of the WCD;
- determining a trend based at least in part on the steps/minute, the steps/6 minutes, and the total daily steps, wherein the trend is indicative of a change in the health condition of the person,
- calculating a wellness parameter based on the trend;
- and
- outputting a recommendation for the person based on the wellness parameter, wherein the recommendation includes at least one of a recommended activity or activity level.
