Chemo-receptors are located peripherally within the aortic and carotid bodies and centrally in the medulla oblongata. In the presence of other reassuring features of the CTG (as outlined above), these decelerations should not be considered as indicative of hypoxia, and interventions should be avoided based on this parameter alone.

Includes quantification of beat-to-beat changes Both components are then traced simultaneously on a paper strip. Within this guideline, the decision to monitor the preterm fetus remains vague with recommendations that each case requires discussion between obstetric and neonatal input, in addition to weighing up likelihood of severe morbidity of the preterm fetus (based on gestational age and fetal weight) and issues related to mode of delivery [1].

This results in parasympathetic activation leading to a fall in heart rate, which is protracted and takes longer to recover to baseline rate. 7.10 Impaired placental circulation B. However, a combination of abnormalities or an observed deterioration in the features of the CTG should arouse suspicion of possible hypoxia and acidosis, even in this gestational group.

Base deficit There are various reasons why oxygen deprivation happens. Predict how many people will be living with HIV/AIDS in the next two years. The transcutaneous PO2 (tcPO2) response to blood interruption (BIS test) was measured in 6 healthy adults and 28 infants, including premature infants. A thorough history of each case should be determined prior to CTG interpretation, and instances where variability is persistently reduced without explanation, should be viewed with caution.Accelerations at this gestation may not be present or may be significantly reduced with a lower amplitude (rise of 10 beats from the baseline rather than 15 beats).
