How safe is safe? The design intent of perfusion safety systems is to offer maximum flexibility, low-cost and fail-safe features. While easily said, these requirements are difficult to deliver in a perfusion world where standardization is uncommon. T

Fetal head molding is the change in shape of the fetal head due to forces of labor. The biomechanics of this process are poorly understood. To understand it better, classical engineering structural analysis is being applied to analyze the process. A

The structural stiffness of 20 parietal bones from 10 fetal cadavers were tested under controlled laboratory settings. The slope at the onset of the load-deflection curve dictated the stiffness of the bone. These values were correlated with the bone'

The fever index is a numerical expression of the total quantity of fever for a patient. A FORTRAN computer program was written to calculate the area above a base line of 99° F., when oral temperatures are recorded at least 4 times a day, and the res

After induction of pneumothorax in rabbits, thermograms showed decreased heat emission from the involved side. These observations suggest that noninvasive monitors of thoracic wall temperature might be useful for early detection of air-leak phenomeno

Forty-five specimens of fetal cranial bone ranging in estimated gestational age from 25–40 weeks were tested in three-point bending. Five specimens of a six-year-old calvarium were tested for comparative purposes. The elastic modulus of each specim

The mechanical behavior of fetal dura mater was investigated by means of a biaxial tension test designed to simulate the constraints imposed on the membrane by the cranial bones. The experimental results are compared with the theoretical results obta

Molding at parturition, as perceived subjectively, ranges from no reshaping to marked distortion of the infant's head. While clinicians easily recognize ,the highly molded head, there are no criteria for quantitating the degree of molding. The purpos
