will flash to indicate which sensors need to be connected for your study some of the following steps showing how to connect certain sensors may not be applicable for your particular sleep study however they all will be reviewed in this program insert the two ends of the abdominal belt wires into the ports on the abdominal belt then insert the blue connector into the lower blue port on the device as each sensor is connected the corresponding display will stop blinking to indicate that you have made the connection correctly now connect the two ends of the chest belt wires into the ports on the chest belt insert that blue connector into the upper blue port of the device next apply the nasal cannula by placing the prongs of the cannula in your nose position the cannula wire over your ears and then secure it comfortably under your chin attach the end of the cannula to the port located near the gray color coding on the device insert the connector in the port by twisting it until it is securely in place position the thermal airflow sensor on your lip and below your nose place the wires from the sensor over your ears and secure it comfortably under your chin bend and position the wire so it is above your lip but not in your mouth apply a piece of medical tape to your cheeks over the wire to help keep them in place while you sleep plug the connector into the port located near the purple color coding depending on the type of study being done your provider may not have included this specific component now it is time to attach the SP o2 sensor to your index finger your provider may have included one of three types of sensors a clip on style a soft sensor and a wrap style sensor first we will review the clip style sensor hold the end of the sensor and squeeze it open so you can insert your finger for the soft sensor lightly squeeze the sides open so you can insert your finger if you have a rap style sensor grasp the blue tab on the table and peel back the paper just enough to expose the cutout portions position the black sensor into the cutout section on the adhesive side press the backside of the sensors firmly into the tape place the tip of your index finger over the lower portion of the sensor fold the upper portion of the adhesive material over your finger refer to the drawing to make sure your finger is properly positioned remove the rest of the
