This is a section largely related to the superspecialised field of looking after patients who have recently had their chest cut open for whatever reason. The questions grouped here are largely those related to cardiotomy, thoracotomy, and cardiopulmonary bypass. By some weird logical extension ECMO and VADs have also ended up in this category, as did the temporary pacemaker. Though these are procedures which involve the use of equipment, these topics seemed too "cardiothoracic" for the Equipment and Procedures section. Also, that section already suffers from severe taxonomy bloat, and could stand to lose some content. Any complaints regarding ridiculous SAQ topic allocation will be resentfully ignored.
