Abstract
THIS GRANT AWARD IS FOR THE DEVELOPMENT OF A NON-INVASIVE BEDSIDE MONITOR OF PULMONARY ARTERIAL PRESSURE IN INFANTS. THE PRINCIPLE OF OPERATION IS DERIVED FROM EARLIER NON-INVASIVE RESEARCH ON HUMANS AND FROM INVASIVE STUDIES ON DOGS, IN WHICH AN IMPROVED METHOD OF NON-INVASIVE DETECTION OF THE TIME OF CLOSURE OF THE AORTIC AND PULMONARYVALVES HAS BEEN DEVELOPED. THE TECHNIQUE DEPENDS ON THE DETECTION OF SUBTLE BUT DISTINCT MOVEMENTS OF THE CHEST WALLOVERLYING THE HEART, MOVEMENTS RESULTING FROM THE FORCES CREATED BY CLOSING AND TENSING THESE VALVES. SINCE THE TIMEINTERVAL SEPARATING THE CLOSURE OF THESE TWO VALVES IS KNOWNTO DEPEND ON THE LEVEL OF PULMONARY ARTERIAL PRESSURE, THE APPLICATION OF THIS TECHNIQUE TO THE PROBLEM OF NON-INVASIVEASSESSMENT OF PULMONARY HYPERTENSION IS A NATURAL EXTENSION OF THIS TECHNOLOGY. THIS TECHNIQUE CAUSES NO DANGER OR DISCOMFORT TO THE CHILD, AND DOES NOT INTERFERE WITH HIS/HERCARE OR TREATMENT. PULMONARY HYPERTENSION IS A CENTRAL FACTOR IN PATHOGENESIS OF PERSISTENT FETAL CIRCULATION AND MAY BE A COMPLICATING FACTOR IN RESPIRATORY DISTRESS SYNDROME. IT IS ALSO A VERY SERIOUS COMPLICATION OF CONGENITAL MALFORMATIONS SUCH AS PATENT DUCTUS ARTERIOSUS. IF THIS RESEARCH IS SUCCESSFUL, A PRACTICAL NON-INVASIVE BEDSIDE MONITOR OF PULMONARY ARTERIAL PRESSURE WILL RESULT, WHICH WILL BE SIMPLE AND INEXPENSIVE SO AS TO BE USEFUL EVENIN SMALL HOSPITALS. THE INSTRUMENT MAY HAVE WIDE RANGING COMMERCIAL APPLICATIONS. THE INSTRUMENT CAN BE OPERATED BY NURSING PERSONNEL. THE TECHNIQUE WILL COMPLEMENT THE RECENTLY DEVELOPED TRANSCUTANEOUS OXYGEN MONITORING INSTRUMENTATION, AND WILL SIGNIFICANTLY EXPAND THE SCOPE OF INFORMATION AVAILABLE NON-INVASIVELY TO THE PHYSICIAN IN THE NEONATAL INTENSIVE CARE UNIT.
