The slope of the response of aldosterone to serum potassium is almost independent of sodium intake.

Low serum potassium increases the risk of digoxin toxicity and cardiac dysrhythmias.

Elevations of serum potassium are common and if the potassium level gets too high special measures must be taken.

The effect of subcutaneously administered terbutaline on serum potassium in asymptomatic adult asthmatics.

His temperature was 37 C, pulse 84/ min, and serum potassium 3.8 mmol/l.

During extreme exercise, potassium is released from active muscle, and the serum potassium rises to a point that would be dangerous at rest.

It can help to protect the myocardium from dangerously high levels of serum potassium in hyperkalemia.

We have to treat for high serum potassium, and we have to do it now!

The amount of aldosterone secreted is a direct function of the serum potassium as probably determined by sensors in the carotid artery.

Dialysis may not be necessary for all people, but is often lifesaving, especially if serum potassium is dangerously high.
