This was the immediate medical order to be carried out, and there was also a long-term order: over the next five days, the patient would need to be given Diuretics and digitalis‑type drugs.
The goal was to rapidly relieve the symptoms of pulmonary edema.
The lungs govern water; when they become edematous, the first thing to consider is not fluid restriction but diuresis.
If the patient also has concurrent renal failure, that situation is very dangerous.
When a certain organ in the body develops a problem, it can actually be like some ancient kingdom being attacked and seeking help from a neighboring state—it can likewise seek help from other organs in the body.
It's just that this "request for help" has to be realized by the doctor through drugs or other methods.
Giving this patient Diuretics was equivalent to the lungs having a problem and asking the kidneys and other organs for help, speeding up the excretion of excess water from the body to ease the pulmonary edema.
