1. A method for reducing errors in an electronic health record (EHR) of a subject comprising:
directly or indirectly acquiring from a sensor configured to detect oxygen saturation (SO2) an acquired value for a parameter that is a function of oxygen saturation of a sample of blood in or obtained from a vascular access device (VAD) disposed in the subject;
performing an evaluation of the acquired value at least by comparing the acquired value with one or more reference values;
based on the evaluation of the acquired value, assigning a first identity classification to the VAD, wherein the first identity classification is one of a central venous catheter (CVC), an arteriovenous access device (AVA), or another class of VAD;
comparing a preexisting identity classification of the VAD to the first identity classification, the preexisting identity classification being part of a preexisting EHR of the subject; and
responsive to determining that the preexisting identity classification does not match the first identity classification, automatically updating the preexisting identity classification to match the first identity classification.
