RACK 310 Any doubt about fetal viability should be checked by listening to the audible signal or by an alternative diagnostic technique A simple check of the ultrasonic system can be made by holding the transducer against the palm of the hand and stroking the back of the hand at a fixed rate say twice per second A clear audible signal should be heard and the digital display should show a rate after approximately five seconds With the printer running this rate will be recorded on the chart Uterine Activity Monitoring The FETATRACK 310 External Uterine Pressure tocodynamometer transducer is used to monitor external uterine activity The transducer is colour coded yellow for ease of identification To monitor uterine activity plug the transducer into the input socket of your choice The FETATRACK 310 EUP transducer is sealed to prevent the ingress of fluids nevertheless no coupling gel or other fluid should come into contact with the transducer face Place the transducer on the center line over the fundus in a position where the uterus is firm and secure in place with stretch belting As with the ultrasound transducer the belt should first be secured in position and then the transducer slid onto it Once the transducer is in position push the UAO button on the front panel to zero the recording The position of the zero baseline can be set to suit individual preference see the section SETTING UP THE FETATRACK 310 Fetal Activity
