Abstract: The present disclosure discloses a method and system for generating a patient-specific content to a patient undergoing medical procedure. The system and the method of the present disclosure receives data related to the patient from various input sources, e.g. care-givers, the patient or data of medical attributes of the patient fed directly by monitoring or diagnostic devices, etc. The system stores a plurality of prior-prepared and existing media files, e.g. video or audio files, each of which may be related to a specific patient health parameter, condition or intended medical procedure or treatment that patient is or will undergo. Based on the specific input data of a patient, the system generates a patient-specific media content, or also can be referred to as personalized content objects (PCOs), that is constituted from at least two of said media files.
