baseline FHR
Average FHR range of 110 to 160 beats/min at term as assessed during a 10 minutes segment that excludes periodic or episodic changes and periods of marked variability TERM 2
bradycardia
DEFINITION 2 persistent (10 minutes or longer) baseline FHR below 110 beats/min TERM 3
prolonged deceleration
DEFINITION 3 visually apparent decrease in the FHR of 15 beats/min or more below the baseline, that lasts more than 2 minutes but less than 10 minutesWorried about the baby TERM 4
periodic changes
DEFINITION 4 changes from baseline patterns in FHR that occur with uterine contractions TERM 5
tachycardia
DEFINITION 5 persistent (10 minutes or longer) baseline FHR greater than 160 beats/min
variability
expected irregular fluctuations in the baseline FHR of 2 cycles per minute or greater as a result of the interaction of sympathetic and parasympathetic nervous system TERM 7
early deceleration
DEFINITION 7 visually apparent gradual FHR decrease starting with the onset of a contraction in response to fetal head compressionNormal for the baby TERM 8
late deceleration
DEFINITION 8 visually apparent gradual FHR decrease after the start of a uterine contraction in response to uteroplacentalinsufficiencythe lowest point occurs after the peak of the contraction and baseline rate is not usually regained until the uterine contraction is overNot good TERM 9
variable deceleration
DEFINITION 9 visually abrupt FHR decrease any time during a contraction in response to umbilical cord compression TERM 10
acceleration
DEFINITION 10 visually apparent abrupt increase in the FHR of at least 15 beats/min or greater above the baseline rate that lasts 15 seconds or more with return to baseline less than 2 minutes from the beginning of the increase
tocotransducer
external monitoring instrument that measures uterine activity transabdominally.it is placed over the fundus TERM 17
spiral electrode
DEFINITION 17 internal monitoring instrument that is attached to the fetal presenting part to assess FHR pattern TERM 18
IUPC
DEFINITION 18 Internal monitoring instrument that is solid or fluid filledit is inserted into the intrauterine cavity to measure uterine activity TERM 19
fetal pulse ox
DEFINITION 19 method of assessment that monitors fetal oxygen saturation levels TERM 20
fetal scalp blood sampling
DEFINITION 20 method used to obtain fetal blood in order to assess the pH of the blood
amnioinfusion
instillation of room-temperature isotonic fluid into the uterine cavity if the volume of amniotic fluid is low to relieve intermittent cord compression that results in variabledeceleration'sand transient fetal hypoxemia TERM 22
oligohydramnios
DEFINITION 22 an abnormally small amount of amniotic fluid TERM 23
anhydramnios
DEFINITION 23 absence of amniotic fluid TERM 24
tocolysis
DEFINITION 24 relaxation of the uterus that can be achieved through the administration of drugs that inhibit uterine contractionsthe most commonly used for this purpose is terbutaline (Brethine) TERM 25
umbilical cord acid base determination
DEFINITION 25 assessment method used immediately after birth as an adjunct to the Apgar scoreit measures pH, PO2, and PCO2 of the newborn's blood and reflects the acid-base status of the newborn at birth
