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

Published

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! :lol2:

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

V- Variable C- Cord compression

E- Early H- Head compression

A- Acceleration O- Okay

L- Late P- Placenta insufficiency

The definition of nadir applies to many situations:

In chemistries, it's the lowest point; in antibiotic monitoring, it's the lowest blood level (pre-dose)l in psych, it's the point the patient feels the worst.... you get the picture.
