NONINVASIVE METHOD FOR MEASURING AND MONITORING INTRAPLEURAL PRESSURE IN NEWBORNS

摘要

-22-Abstract of the DisclosureIntrapleural pressure of a newborn subject ismeasured by detecting relative movement betweenadjacently-proximate cranial bones. The preferred devicefor measuring such bone movements is a surface inductiveplethysmographic transducer secured on the subject's headacross at least two adjacently-proximate cranial bones.The output signal generated by the transducer may be cali-brated to provide a measurement of actual intrapleuralpressure by temporarily manually occluding the subject'snose or, if intubal, the endotracheal tube, measuring theairway pressure during such occlusion as the newborn makes an in-spiratory effort, and adjusting the transducer output sig-nal to equal the airway pressure measured with the noseoccluded.
