Noninvasive measurement of pulmonary artery blood flow has widespread implications for management of newborn infants requiring intensive care. Using a precordial, unguided, single Doppler technique, we evaluated right ventricular output in 26 preterm and 16 term infants without cardiopulmonary problems and compared it with right ventricular output obtained by duplex Doppler scanning and left ventricular output measured by a suprasternal single Doppler approach. Weights ranged from 1,120 to 3… CONTINUE READING
