Alarms Due to Loss of Signal Integrity in Partially Wireless Versus Traditional Pulse Oximetry in Pediatric Patients

The Radical 7 is the traditional wall-connected pulse oximeter currently used at Children's Hospital of Wisconsin (CHW) which requires a 12 foot cable connecting the patient to a wall unit. While being continuously monitored with the Radical 7 pulse oximeter, subjects will be asked to complete age appropriate activities. The pulse oximetry data will be analyzed for instances of alarm state corresponding to loss of signal integrity as defined by complete inability to pick up the subject signal or a change in the pulse oximetry saturation value by 4%.

The Radius 7 is a newer, partially wireless pulse oximeter which eliminates the cable connecting the patient to a wall unit by instead connecting to a small device worn on the patient's arm or leg. The small device then sends the continuous pulse oximeter data wirelessly to the central monitoring station. While being continuously monitored with the Radius 7 pulse oximeter, subjects will be asked to complete age appropriate activities. The pulse oximetry data will be analyzed for instances of alarm state corresponding to loss of signal integrity as defined by complete inability to pick up the subject signal or a change in the pulse oximetry saturation value by 4%.
