The objective of this study is to collect heart rate, respiration data and motion data of patients admitted to sleep lab and to determine the current accuracy level of the EarlySense system vs. the standard system, and predicate device for EarlySense (Embla) used in sleep lab in monitoring heart rate and respiration rates monitors (ECG, respiratory belts, oximeter) that are currently used in the sleep lab among different population (Obese, patients with or without apnea, patients with or without arrhythmia). It is emphasized that no interpretations or clinical decisions will be made based on data received from the ES study device.
