Ultrasound interface unit and method

An ultrasound interface unit, communicatively coupleable in use with both:

• an ultrasound sensing apparatus and a patient monitoring unit, said ultrasound interface unit configured in use to:
• receive from the ultrasound sensing apparatus acquired ultrasound data representative of a subject, and perform processing of said data to derive at least one physiological or anatomical parameter related to the subject;
• generate a data output representative of said derived parameter and communicate said data output to the patient monitoring unit, and
• perform a configuration function comprising communicating with the ultrasound sensing apparatus to cause adjustment of one or more image-related operating parameters of the ultrasound sensing apparatus for configuring the ultrasound sensing apparatus to acquire ultrasound data suitable for monitoring said physiological or anatomical parameter over time.
