The kidney plays a critical role in the regulation of acid-base, potassium, and sodium balance, a role that can be compromised by a decrease in kidney function caused by CKD (defined as an eGFR < 60 mL/min/1.73 m2). Cell K+ concentration is about 150 mmol/l but varies in different organs. Our new CrystalGraphics Chart and Diagram Slides for PowerPoint is a collection of over 1000 impressively designed data-driven chart and editable diagram s guaranteed to impress any audience. Electrolytes are ions, or charged particles, that can carry an electric current across cells to support a variety of physiological processes. Diuretic use is a common cause of renally mediated hypokalemia.10 When given in the same dosage, chlorthalidone is more likely to induce hypokalemia than hydrochlorothiazide, which is more often implicated because of its widespread use.11,12 Diuretic-induced hypokalemia is dose-dependent and tends to be mild (3 to 3.5 mEq per L [3 to 3.5 mmol per L]), although it can be more severe when accompanied by other causes (e.g., gastrointestinal [GI] losses).13 We use your LinkedIn profile and activity data to personalize ads and to show you more relevant ads.
