Is There a SIADH in This Patient?

The patient's SAT is 89%. She's hypertensive and mildly tachycardic. Despite her concerns regarding fever, she actually is and has been normal thermic in the ER. The sodium of 128 may be related to a cardiac source if she has other examination evidence like petal edema or history of what might be congestive heart failure symptoms such as general fatigue that she complains of. And also, SIADH is very common in lung disease generally.
