                5. Variable deceleration:
                variable decelerations are irregular, often jagged dips in the fetal heart rate that

               look more dramatic than late decelerations.
               Causes:
               - Intermittent compression of umbilical cord by fetal head.

               - Oligo hydrominos.
                - Cord between fetus and mother's uterus or pelvic without obvious prolapse.
               Management:

                - Change maternal position to decrease cord compressive (turn sides to side or
               knee chest position).
                - Give O2 at 8 – 10 L/min by tight face mask.
                - Improve circulating volume.

                - Amnion per fusions.
                - Monitor for change fetal heart pattern dis continue oxytocin if it being

               administered.
                - Perform vaginal examination to assess for prolapsed cord

               6. Prolonged deceleration:

                there are isolated deceleration which last longer than 60 – 90 seconds.
                Causes:
                - Tetanic uterine contractions.

                - Placental abruption.
               - Umbilical cord prolapse.
               - Maternal hypoxia.

               Management: - Notify physician or mid wife of first occurrence.
                - Check for cord prolapse.
                - Examine the cervix.

                - Check progress of dilation and descent.
                - Correct maternal hypotension increase intravenous fluids.
                - Continuous observation until delivery be prepared for emergency delivery.


               7-Sinusoidal pattern:
                    it indicates fetal anemia as in case of ruptured vasa praevia, feto maternal

                   haemorrhage, twin-to-twin transfusion syndrome, and Rh-immunization.
                 Causes:
