Lung area to Head circumference Ratio (LHR) Calculator

WebThe lung-to-head ratio, or LHR, is a numeric estimate of the size of the fetal lungs, based on measurement of the amount of visible lung. High LHR values greater than 1.0 are associated with better outcomes. WebAssessment of severity is by measurement of contralateral lung area in a transverse section of the chest to head circumference ratio (LHR). The measured LHR is compared to the LHR in normal babies and the disease is classified as severe if the ratio is < 25%, moderate if 26-45% and mild if >45%. fahrrad barth
