Yakakosha Potassium Emergency: Hyperkalemic Cardiac Kusungwa uye Hypokalemic Paralysis¶

Potassium (K+) ndiyo yekutanga intracellular cation mumuviri wemunhu, ine ** 98 muzana yemuviri wese potassium (3,500 to 4,000 mEq) yakachengetwa mukati meskeletal muscle uye nhengo dzemasero ** uye chete ** 2 muzana inotenderera muropa re extracellular **. Nekuti magetsi ekuzorora membrane anogona (-90 millivolts) uye repolarization yemoyo wese tsandanyama sero uye skeletal tsandanyama nerve fiber zvinoenderana nehupamhi hwemawere pakati peintracellular potassium (140 to 150 mEq/Luye extracellular serum potassium (3.5 to 5.0 mEq/L), kunyange kuchinja kuduku kwepotassium kupinda kana kubuda muropa kunogona kumisa mwoyo kana kuomesa muviri mukati memaminitsi mashoma.
