Version 2.77


Low ionized calcium levels are common in critically ill patients with sepsis, renal failure, cardiac failure, pulmonary failure, post-surgery or burns. Monitoring of ionized calcium is particularly important in the unconscious or anesthetized patient, in whom unrecognized changes in calcium homeostasis may result in serious cardiovascular dysfunction with little of no prior warning signs. Decreased ionized calcium levels between 3 and 4 mg/dL are usually well tolerated, but the risk of cardiac arrest increases when ionized calcium levels approach 2.5 mg/dL. An ionized calcium level below 2.8 mg/dL is a reasonable threshold to begin calcium replacement therapy. Patients with hypotension or low cardiac output may require calcium replacement when ionized calcium falls below 3.2 to 3.6 mg/dL. Ionized calcium levels should be monitored during replacement therapy. Copyright Copyright © 2006 - 2008 ClinLab Navigator, LLC. Source: ClinLab Navigator, Ionized calcium
