Abstract
A physiological parameter sensing system receives signals from (on includes) a first physiological parameter sensor and an activity monitor. The first physiological parameter signal is used to determine when additional physiological parameter sensing is recommended and an alert is then generated. The alert has characteristics which depend on the type and/or level of activity currently being undertaken by the user. In this way, the alert can be selected so that it is perceived by the user but without being an annoyance.
Claims12
A physiological parameter sensing system, comprising:
- at least one first physiological parameter sensor;
- at least one activity monitor;
- a controller, wherein the controller is adapted to:
- receive physiological signals from the at least one first physiological parameter sensor;
- analyze the physiological signals to identify an abnormal vital sign thereby to determine when additional physiological parameter sensing is recommended;
- receive activity signals from the at least one activity monitor;
- analyze the activity signals to determine a type and/or level of activity;
- and
- in response to the determinations, generate an alert signal for creating an alert having characteristics that depend on the type and/or level of activity,
- wherein the alert is configured to obtain the attention of a user;
- and
- an input device for receiving a user input in response to a generated alert;
- wherein the controller is further adapted to measure the time which elapses between the generation of the alert and the received response of the user to the generated alert.
A method of generating an alert in response to sensing of a physiological parameter, comprising:
- monitoring a physiological parameter using a first physiological parameter sensor;
- analyzing the physiological parameter to identify an abnormal vital sign thereby to determine when additional physiological parameter sensing is recommended;
- monitoring an activity of a user using an activity monitor to determine a type and/or level of activity;
- in response to the determinations, generating an alert having characteristics that depend on the type and/or level of activity, wherein he alert is configured to obtain the attention of a user;
- receiving a user input in response to a generated alert;
- and
- measuring the time which elapses between the generation of the alert and the response of the user to the generated alert;
- wherein the method further comprises updating a mapping between the alert characteristics and the type and/or level of activity based on the timed response.
