ABSTRACT
The pulmonary flow pattern was analysed by pulsed Doppler in 77 normal neonates, at < 48 hours (36 subjects), 49 to 96 hours (25 subjects) and 97 to 148 hours (16 subjects). From the flow velocity spectrum, using an built in computer system, the acceleration time and the ejection time were measured, and the ratio was calculated. This ratio was 0.24 +/- 0.08 in the subjects within 48 hours whereas this ratio was 0.53 +/- 0.11 in the subjects above 97 hours; thus the ratio increased with age. We noticed that the ratio obtained from the pulsed Doppler is useful in assessing the pulmonary vascular status, even in neonates.
