what are the 3 reason O2 is given? - ✔✔decrease WOB, Tx hypoxemia, decrease myocardial work
Radiolucent - ✔✔dark air pattern
radiodense - ✔✔white pattern solid fluid
infiltrate - ✔✔any ill defined radio density
consolidation - ✔✔solid white area
hyperlucency - ✔✔extra pulmonary air
vascular markings - ✔✔Lymphatic vessels lung tissue ( increased markings in CHF, decreased markings
with pneumothorax)
diffuse - ✔✔spread throughout
