1. A system for respiratory monitoring of a subject, said system comprising:
a bioimpedance measurement sensor, which is configured for arrangement in relation to the subject for acquiring a bioimpedance signal; and
a processing unit, which is configured to receive the acquired bioimpedance signal and receive a reference signal, the reference signal representing an amount of respiratory effort of the subject or an amount of respiratory airflow at a time of bioimpedance signal acquirement, the processing unit being further configured to process the bioimpedance signal using information in the received reference signal to separate the bioimpedance signal into an effort signal component and a flow signal component, the effort signal component representing the respiratory effort of the subject, and the flow signal component representing the respiratory airflow of the subject,
wherein the bioimpedance measurement sensor is arranged on a carrier configured for being arranged on a region of the body of the subject.
