This study aims to provide myriad of physiological parameters in patients admitted in an internal medicine department, and which are defined as being in an increased risk of clinical deterioration within the first 72-hours after admission. The investigators will also conduct a retrospective comparison between physiological changes in patients who did deteriorate to those who did not. This will form the basis for the development of an algorithm for early prediction and warning of physiological and clinical deterioration during the first 72-hours of admission.

Inclusion Criteria:

• Males and females 18 years old and above admitted to the internal medicine department
• On admission, the primary investigator assess their risk to deteriorate during the first 72 hours after admission as reasonably high
• The patient is assigned to a "monitoring bed" within the department
• The patient has signed an informed consent form

Exclusion Criteria:

• Lack of informed consent
• It is known in advance that the patient cannot take part in the study for a 72-hours period (e.g. a patient that will be taken to surgery within the next 24 hours)
• Technical inability to attach the Biobeat patch (BB-613PW) to the patients chest

Male and female patients 18 years and older admitted to the internal medicine department and are at high-risk for clinical deterioration during the first 72-hours after admission. The investigators anticipate it will include patients with acute and chronic cardio-respiratory disease, systemic infections, etc.

The investigators plan to publish the data in a way that will allow all readers to access the data collected and analyzed
