What Is an Arterial Blood Gas Test? An arterial blood gas test, commonly known as an ABG, is performed on blood from an artery. It is used to see how well the lungs are functioning and to determine the effectiveness of respiratory therapies, such as the use of a ventilator, CPAP, BiPAP or oxygen.
Drop Date â is the last day in a semester when a student can withdraw from a course before course completion without having a grade assigned for the class. Students that are likely to fail a course may decide to drop (withdraw from) the course to avoid having a failing grade lower their overall grade point average.
What does it mean to drop a course? This section concerns dropping a course from a student's class schedule. If a student wishes to drop a course (or courses), this means that he/she will drop one or more classes from a specific semester or term while still staying enrolled in at least one course. UW-Madison does not refer to this process as withdrawing from a class. If a student wishes to drop all of his/her classes and not stay enrolled in any classes for a specific semester or term, the student will need to formally withdraw from the semester.
