prolapsed cord

[nfeese]

So, if a prolapsed cord causes variable decels this indicates that at some point compression is letting up? Ok, if this is true how does an engaged fetus with a mashed cord relent? That makes no sense, because to me it would be more of a continued compression in which FHR wouldn't return to baseline. If the compression occurs primarily with contractions then why wouldn't the decels be predictable in regards to the ctx ie late or early. I mean a baby squeezing the cord can cause a variable decel which has no relation to a contraction. Can a contraction cause the intermittent compression leading to variable decels in prolapse cord and if so why are they called variable decels? Thanks

2) I think you are confusing "prolapsed cord" with "cord occlusion."

I generally agree with your post, but technically speaking, a prolapsed cord is occluded, often in a permanent sense, especially if baby's head is engaged in the maternal pelvis and the cord is between kiddo's head and mom.

See, that's what I would think also. Like a complete blockage of flow... in which case increasing moms BP and O2 isn't going to matter. Maybe once a nurse pushes on the presenting part to relieve compression, the O2 and bolus would help... idk

Once you realize you have a prolapse, you would push baby's presenting part off the cord immediately. THEN you have someone else start the bolus and O2, in which case yes, increased SPO2 and blood volume will better perfuse and oxygenate the placenta, and by default, baby, via the relieved cord.

Yes, it absolutely helps. That's why it's done!
