The EarlySense Chair Sensing Unit is intended to be used for continuous measurement of Respiration Rate, Heart Rate and Movement, in an automatic contact-less manmer, at horn; hospital or clinic setting. The sensor is indicated for use in children, adolescents and adults. The operation of the EarlySense system has been studied in children (weight ?: 10 Kg) and adults (weight <1I I Kg) during sleep and resting condition, The Chair Sensing Unit can be used with bedside units that contain appropriate software (graphical interface) that can support reading and displaying EarlySense Chair Sensing Unit readings. In addition, the EarlySense System call continuously monlitor oxygen saturation of arterial hemoglobin (SpO 2) using pulse oxinietry in pediatric (ages 2 years and oider), adolescents and adults at home, hospital, or clinical settings.
