Fetal Monitoring
Test #3
Question | Answer |
---|---|
Transducer | monitors fetal hr, placed over fetal back |
Tocotransducer | monitors cx frequency and duration *not accurate for intesity |
Baseline FHR | 10 minutes of average FHR without contractions |
Short-term variability | beat to beat variation |
Long-term variability | cyclic variation over a period of time |
Non-periodic changes | accelerations of FHR with fetal movements |
Accelerations | increase in FHR over the baseline with cxs |
Variable decelerations | *r/t umbilical cord compression (V U W shaped) - not related to cx pattern - interventions- change positions, IV fluids, 02 mask 5-10liters |
Early decelerations | r/t head compression (not bad) mirrors cx |
Late decelerations | r/t decrease in uteroplacental perfusion (fetus is becoming acidodic)- change postition, IV bolus, 02, give tocolytic, prep for c-section |
