Abstract

The invention relates to a method and device for recording and presentation of physiological parameters, which can include both blood pressure and heart pulse. Information about the heart pulse is derived from a recorded blood pressure signal, whereby the need for e.g. an external ECG measurement device is eliminated. It is likewise a part of the invention that a blood pressure measurement is used for the derivation of data such as Heart Rate Variability (HRV) and/or baroreflex sensitivity (BRS) values.

Claims

1. A hand-held measurement device for facilitating patient self-measuring and recording, the hand-held measurement device comprising:

a housing, and a pressure transducer, a display, electrocardiogram (ECG) electrodes, and a processor, each of which is within the housing, the processor being configured to;

measure, via the pressure transducer, an exhalation pressure of a patient during a time period associated with an examination;

cause a first graphical component indicating the exhalation pressure measurement to be presented on the display such that the first graphical component is continuously updated in real-time, as the exhalation pressure is being measured, until at least the end of the time period associated with the examination;

cause a second graphical component indicating a remaining time of the time period to be presented on the display such that the second graphical component is continuously updated in real-time, as the exhalation pressure is being measured, until at least the end of the time period associated with the examination;

measure, via the ECG electrodes, a heart rate of the patient during the time period associated with the examination; and

calculate heart rate variability of the time period associated with the examination based on the heart rate measurement and cause a graphical component indicating the heart rate variability to be presented on the display.

2. The hand-held measurement device according to claim 1, wherein the processor is further configured to:

measure, via the pressure transducer, a blood pressure of the patient during the time period associated with the examination.

3. The hand-held measurement device according to claim 1, wherein the processor is further configured to:

measure, via the pressure transducer, a hand grip squeeze pressure of the patient during the time period associated with the examination.

4. The hand-held measurement device according to claim 1, further comprising a baroreflex sensitivity recording unit.

5. The hand-held measurement device according to claim 1, further comprising a plurality of push buttons configured to provide control signals to the processor.

6. The hand-held measurement device according to claim 1, wherein the hand-held measurement device is adapted to simultaneously measure pressure and ECG signals.

7. The hand-held measurement device according to claim 1, wherein the processor is further configured to:

cause step-by-step instructions for using the hand-held measurement device to perform patient self-measuring to be presented on the display during the examination and prior to the time period associated with the examination.

8. The hand-held measurement device according to claim 1, wherein the processor is further configured to:

cause step-by-step instructions for using the hand-held measurement device to perform patient self-measuring to be presented on the display prior to and during the time period associated with the examination.

9. The hand-held measurement device according to claim 1, wherein the processor is further configured to:

cause one or more results of the examination to be presented on the display subsequent to the time period associated with the examination.
