What causes a prolonged deceleration?
Management of Prolonged Decelerations. A prolonged deceleration may be secondary to fetal hypoxia caused by reduced utero-placental perfusion or sustained cord compression. The fetal response to acute hypoxia is a chemoreflex response leading to prolonged deceleration and increased peripheral resistance.Click to see full answer.

Management of Prolonged Decelerations. A prolonged deceleration may be secondary to fetal hypoxia caused by reduced utero-placental perfusion or sustained cord compression. The fetal response to acute hypoxia is a chemoreflex response leading to prolonged deceleration and increased peripheral resistance.Click to see full answer. Similarly one may ask, what is a prolonged deceleration?Finally, prolonged deceleration is defined as an apparent decrease in FHR below the baseline, measured from the most recently determined portion of the baseline. The decrease in the FHR is 15 beats per minute or more and lasts at least 2 minutes but less than 10 minutes from onset to return to baseline.Also Know, what causes late decelerations? They are caused by decreased blood flow to the placenta and can signify an impending fetal acidemia. Typically, late decelerations are shallow, with slow onset and gradual return to normal baseline. The usual cause of the late deceleration is uteroplacental insufficiency. In this regard, how do you find prolonged decelerations? Prolonged deceleration : A decrease in FHR of > 15 beats per minute measured from the most recently determined baseline rate. The deceleration lasts >= 2 minutes but less than 10 minutes. These decelerations appear to be mediated by arterial chemo receptors in mild hypoxia.What is fetal deceleration?A deceleration is a decrease in the fetal heart rate below the fetal baseline heart rate. An early deceleration is defined as a waveform with a gradual decrease and return to baseline with time from onset of the deceleration to the lowest point of the deceleration (nadir) >30 seconds.
