head compression or stretching of the neck during uterine contraction

4

Early Decels:

10-14 bpm

5

Early Decels:

should you worry about early decels?

no they are benign

6

Early Decels:

decribe the strip seen

 

mirror the uterine contraction

10-14 bpm decrease with each contraction

Start and end with comtraction

Uniform in appearance

 

7

Late Decels:

what is the etiology?

Uteroplacental insufficiency

and fetal compromise w/ decrease in HR

8

what strip rhythm is most likely to go for C-section 1st

Late Decels:​

Late Decels:​

describe the strip
