Abstract: Apparatus and related methods for continuous long- term non-invasive measurement of the pressure of a pulsatile fluid flowing through a flexible tube, particularly human arterial blood flow, is disclosed. Specifically, the apparatus provides a continuous calibrated pressure measurement by first undertaking a «calibration» phase comprised of determining the pressure at varoius pre-defined conditions of flow and, in response thereto, ascertaining the values of a plurality of coefficients each of which is associated with a corresponding term in a pre-defined function that characterizes fluid pressure in relation to pulsatile displacement of the wall of the tube; and second, undertaking a continuous monitoring» phase comprised of determining each subsequently occurring pressure value as the pre-defined function of each corresponding pulsatile wall displacement value, and re-initiating the calibration phase at the expiration of pre-defined time intervals which adaptively change based upon current and prior results. Methods, which are particularly useful in conjunction with the disclosed apparatus, for ascertaining systolic and diastolic arterial blood pressure values are also disclosed.

Abstract: A system for noninvasively sensing ocular pulses of a mammal, which pulses serve as a basis for indicating presence of a disease or malfunctioning body part such as, for example, a condition of arterial occlusion. The system employs piezoelectric transducers to sense the ocular pulses which are analyzed, also, in the case of arterial occlusion with simultaneously obtained ECG signals.

Abstract: A fiber-optic transducer apparatus, and a related method of manufacturing it, for particular use in medical applications such as invasive blood pressure and body temperature measurement. The apparatus includes a catheter comprised of a sheath and an enclosed first set of optical fibers for transmitting a light beam to and from the remote end of the catheter, where a transducer modulates it in accordance with the variable to be measured, e.g., blood pressure. A photosensor located at the near end of the catheter measures the modulated intensity of the returned beam, to produce a corresponding measurement signal. The catheter is further comprised of a second set of optical fibers located within the sheath, for transmitting a reference light beam to and from the remote end of the catheter. A second photosensor measures the intensity of the returned reference light beam, to produce a correction signal indicative of variations in transmittance caused by bending of the catheter. ft is presumed that the effects of such bending are the same for the second set of optical fibers as for the first set, so the apparatus adjusts the measurement signal in accordance with the correction signal, to produce an adjusted measurement signal that is substantially insensitive to the effects of such bending.

Abstract: A method and apparatus is disclosed for determining the energy requirements of premature newborns. The method includes identifying a series of groups of newborns in which the age and weight of each newborn within each group are within defined ranges. A characteristic mathematical relationship is generated for each group and relates the mean heart rate to the man energy expenditure over the group. The mean heart rate of a subject newborn is determined and the energy expenditure which is to be determined is measured and applied to the mathematical relationship appropriate to the group into which the subject falls, so as to determine the mean energy expenditure appropriate to that mean heart rate, said expenditure indicating the energy requirement of the subject.

Abstract: Heart rate monitoring apparatus and a related method for detecting the successive beats of a heart and providing a reliable estimate of heartbeat rate. The apparatus comprises a heart rate monitor comprising: means (15) for measuring the time intervals between successive beats of a heart and for producing a corresponding sequence of timing measurements; microprocessor means (17) for grouping the timing measurements into a prescribed set and adjusting a particular measurement of the set in a prescribed fashion, to produce an adjusted set of timing measurements, and for averaging the adjusted set of timing measurements, to produce an estimate of heartbeat rate. The particular measurement that differs most from the computed average is adjusted to be equal to that average, and the adjusted set of measurements is then averaged. These latter steps of adjusting and averaging are repeated a prescribed number of times, and the last-computed average is displayed as an estimate of heartbeat rate on a display (19). The entire procedure is repeated upon the occurrence of each successive heartbeat.

Abstract: Blood pressure measurement apparatus comprises means (10-13) for variably occluding a body zone (16) by progressive application of external pressure between levels respectively above systolic and below diastolic, means (14,15) for detecting variations in blood volume in said zone during variable occlusion thereof, and means (20) responsive to the occluding and detecting means to indicate as systolic and diastolic pressures the values of said external pressure respectively when the maximum and minimum detected volume levels are each about half way between zero and the maximum level following the last minimum which does not depart significantly from zero. The blood volume variations are preferably determined by reference to light transmission through the zone, suitably infrared, but other measures are suitable as determined by strain gauge, proton magnetic resonance or microwave absorbtion.
