Failure of the mature hemodialysis arteriovenous fistula (AVF) is frequently suspected during monitoring designed to detect stenosis so that it can be identified and treated prior to thrombosis, usually on the basis of physical examination findings, flow measurements, or duplex ultrasound [2,3].
An objective perspective is one that is not influenced by emotions, opinions, or personal feelings - it is a perspective based in fact, in things quantifiable and measurable. A subjective perspective is one open to greater interpretation based on personal feeling, emotion, aesthetics, etc. For example: I may take an objective perspective that the Bible is the most published book in all of history.
Objective can be defined as not being influenced by personal feelings or opinions. Subjective can be defined as based on personal opinion. A statement that is completely unbiased is objective whereas a statement that is characterized by the thoughts and the views of the speaker is subjective. Objective is not characterized by any previous experience of the speaker whereas subjective is certainly characterized by the previous experiences of the speaker.
