(20) and configured for generating guiding information comprising a recording procedure to follow when performing the recording;

means for processing the chest signal (21) such as to determine a confidence criterion of the chest signal (21);

the remote control device (10) being further configured for generating instructional information comprising information about the determined confidence criterion, and comprising an interface (1 1) allowing the user, or an assistant performing the recording on the user, to initiate and/or stop the recording or initiate a further analysis of the processed chest signal (21).

2. The system according to claim 1 ,

wherein the first sensor (12) is configured for recording a vibration from the user's chest such that the chest signal (21) is a vibration signal.

3. The system according to claim 2,

wherein the first sensor (12) comprises a sound transducer.

4. The system according to claim 2,

wherein the first sensor (12) comprises a contact microphone or a motion sensor.

5. The system according to any one of claims 1 to 4,

wherein the sensing unit (20) is further configured for measuring a complementary signal (22) from the user.

6. The system according to claim 5,

wherein the computing unit (15) configured for using the complementary signal (22) in combination with the chest signal (21) for determining the confidence criterion.

7. The system according to claim 5 or 6,

wherein the sensing unit (20) comprises a motion sensor such that the complementary signal (22) comprises a motion signal.

8. The system according to any one of claims 5 to 7,

wherein the sensing unit (20) further comprises an electrical signal measuring sensor such that the complementary signal (22) comprises an electricalsignal.

9. The system according to claim 8,

wherein the electrical signal measuring sensor comprises one of an electrocardiograph (ECG), or an impedance cardiograph (ICG) or an electromyograph (EMG).

10. The system according to any one of claims 5 to 9,

wherein the sensing unit (20) further comprises an optical sensor such that the complementary signal (22) comprises an optical signal.

1 1. The system according to claim 10,

wherein the optical sensor comprises one of a PPG sensor or a camera for measuring visual signal.

12. The system according to any one of claims 5 to 1 1 ,

wherein the sensing unit (20) further comprises a blood pressure sensor such that the complementary signal (22) comprises a blood pressure signal.

13. The system according to any one of claims 1 to 12,

wherein the sensing unit (20) and the control device (10) are comprised in a single device to be worn by the user.

14. The system according to any one of claims 1 to 12,

wherein the control device (10) is remote from the sensing unit (20), the sensing unit (20) being configured for transmitting the chest signal (21) and the complementary signal (21) to the control device (10).

15. The system according to any one of claims 1 to 14,

comprising a strap (3) comprising the sensing unit (20), the strap being configured to be worn on the user's torso such that the sensing unit (20) is in contact with the user's skin.

16. The system according to any one of claims 1 to 15,

wherein the interface comprises a display unit (1 1) or speaker device 16 (16).

17. The system according to claim 16,

wherein the interface is further configured for signaling to the user or assistant said guiding information and instructional information.

18. The system according to any one of claims 1 to 17,

comprising a storage media (14) configured for storing the processed chest signal (21).

19. Method for recording signals of a user using the system according to any one of claims 1 to 18, the method comprising:

connecting the sensing unit (20) with the remote control device

(10);

recording a chest signal (21);

using the remote control device (10) for generating guiding information comprising a recording procedure to follow when performing the recording;

processing the measured chest signal (21) such as to determine a confidence criterion of the chest signal (21); and

using the remote control device (10) for generating instructional information comprising information about the determined confidence

criterion to initiate and/or stop the recording or initiate a further analysis of the processed chest signal (21).

20. The method according to claim 19,

wherein guiding information includes breathing guidance information.

21. The method according to claim 20,

wherein guiding information includes at least one of the following actions: how to inspire, how to expire, stop breathing, move chest without breathing, cough.

22. The method according to any one of claims 19 to 21 , including a step of generating initial information comprising a

predetermined location where the user, or an assistant, should place the first sensor (12) on the user's chest.

23. The method according to any one of claims 19 to 22, wherein the step of initiating a further analysis comprises analyzing the processed chest signal (21) by a computer software expert
