Why Do We Give Calcium in Hyperkalemia? ⚠️Added:
Earlier we talked about how hyperkalemia can stop the heart, but why do we give calcium if it doesn't lower the potassium?
A simple reason is because calcium stabilizes the cardiac membrane. It helps reduce dangerous [music] arrhythmias and protects against potential cardiac arrest.
