I was wondering if someone could help me out with a question about CVP. I am a nursing student. Can someone please tell me what nursing assessments should be done to assess for a high or low CVP? I understand that a high pressure indicates fluid overload or HF, and a low value may indicate low volume or dehydration. All I am really coming up with is I & O, lung sounds, respirations, jvd and edema in extremities. I know there has to be more. Thank you.
