OB Question -What is "nadir" in regards to fetal monitoring strips?

  1. 1
    Hello everyone, I just started OB this semester and would like to know what is the definition of "nadir" in regards to fetal monitoring strips and NOT chemotherapy? Every time I search it online, it states solely for chemo, but that's not what I'm looking for; and my clinical instructor couldn't explain to our group either, but said she'll look into it. If you can explain to me like I'm 4 years old, I'd appreciate it!

    Also, I wouldn't mind someone's simpler explanation of deceleration types and any references you have that may help. Thank you much!

    Nadir is the lowest point after the onset of an early/late deceleration and variable.

    We used VEAL CHOP

    V- Variable C- Cord compression
    E- Early H- Head compression
    A- Acceleration O- Okay
    L- Late P- Placenta insufficiency
