What does the abbreviation "PO" stand for?

The abbreviation "PO" stands for "Per os," which is a Latin term meaning "by mouth." This term is commonly used in medical contexts to indicate that a medication, nutrient, or fluid should be taken orally. In the context of EEG and patient care, this can be relevant when discussing the routes of administration for medications that may influence brain activity or the condition of a patient being monitored.

Understanding "Per os" is important for healthcare practitioners as it emphasizes the method of intake that can have significant implications on patient management and treatment protocols. For example, when prescribing medications that affect neurological status, knowing whether the medication needs to be given orally might impact its effectiveness and the timing in relation to EEG monitoring.
