Collect data from the CardiacSense1's sensors and Capnograph, for the purpose of developing a wearable system for monitoring of Respiratory Rate (RR) in patients while at hospital

Hospitalized subjects, diagnosed with a Respiratory disease or subjects with no known Respiratory disease will be will be connected simultaneously to CardiacSense watch and Capnograph for a duration of at least 30 minutes and up to 24 hours in order to collect data for the purpose of developing a wearable system for monitoring of Respiratory Rate (RR) by the CardiacSense watch.

The CardiacSense1 is a wrist worn device designed to detect atrial fibrillation. CardiacSense1 senses the radial artery inflation and deflation and together with a PPG sensors give an ultimate performance that is superior to PPG only.

Inclusion Criteria:

• Age of eighteen (18) year and above
• Diagnosed with Respiratory disease/impairment or without any known Respiratory disease/impairment
• Ability and willingness to sign an informed consent form

Exclusion Criteria:

• Subjects who are currently enrolled in another clinical investigation in which the intervention might compromise the safety of the subject's participation in this study
• Patients with significant co morbidities (assessed by the clinician at screening only
• BMI>40
• Presence of an acute disease process that might interfere with test performance
• Subjects with PPG SNR <100 indicated by the CardiacSense1 device
• Women who are pregnant or breastfeeding
