- *RVSP = right ventricular systolic pressure, referring to pulmonary hypertension.
- †AaDO2 = alveolar-arterial oxygen gradient.
- ‡HIT = heparin-induced thrombocytopenia, which is a thromboembolic complication that can occur with unfractionated heparin (UFH) or low molecular weight heparin (LMWH).
