PPT-Clinical significance and interpretation of Blood Urea Nitrogen

VLD411 Urea or Blood Urea Nitrogen Urea is the major excretory product of protein metabolism formed in the liver from amino groups NH2 and free ammonia generated during protein catabolism Enzymatically catalyzed process is termed the urea cycle. 6 Low risk consider home treatment 1311142 27 2 691019 68 Short inpatient hospitalization or closely supervised outpatient treatment 3 79563 140 Severe pneumonia hospitalize and consider admitting to intensive care 4 or 5 44158 278 CRB65 score Deaths C483 Spring 2013. 1.
