Physiology of the newborn infant

A Model of the Respiratory System in the Newborn Infant

A dynamic mathematical model is presented which successfully simulates the respiratory control system of the newborn infant in different physiological conditions. The primary objective in constructing this model has been to provide a simulation aid in the investigation of maturation of the respiratory system, and the respiratory disorders during the newborn period, without the need for invasive...

Hypoxia in the newborn infant

Many disorders of breathing in the newborn period arise because of failure of normal cardio-pulmonary adaptation. In order to understand the pathogenesis of these disorders it is necessary first to summarize the changes that normally take place in the lungs and circulation at birth. In fetal life the respiratory centre is not, as was once thought, inactive. Breathing movements in utero, first s...

Hats for the newborn infant.

The efficacy of a Gamgee-lined hat in reducing the rate of fall in rectal temperature of infants during the first 30 minutes of life was studied. The trial, which included 211 infants, was randomised, prospective, and controlled. One hundred and seven infants were exposed to overhead radiantheaters. Of these, only 30 had normal deliveries, so the analysis was confined to the infants who were no...

Hypoxia in the newborn infant.

Hypoxia in newborn infants is becoming much easier to prevent, detect and treat. Nevertheless the successful management of potentially hypoxic fetuses and newborn infants remains the major challenge to all physicians concerned with perinatal care. What is at stake is not only that sick infants should survive, but equally or more importantly that the survivors should be normal children. Recent f...
