A system for determining a biologic constituent including hematocrit transcutaneously, noninvasively and continuously. A finger clip assembly includes including at least a pair of emitters and a photodiode in appropriate alignment to enable operation in either a transmissive mode or a reflectance mode. At least one predetermined wavelength of light is passed onto or through body tissues such as a finger, earlobe, or scalp, etc. and attenuation of light at that wavelength is detected. Likewise, the change in blood flow is determined by various techniques including optical, pressure, piezo and strain gage methods. Mathematical manipulation of the detected values compensates for the effects of body tissue and fluid and determines the hematocrit value. If an additional wavelength of light is used which attenuates light substantially differently by oxyhemoglobin and reduced hemoglobin, then the blood oxygen saturation value, independent of hematocrit may be determined. Further, if an additional wavelength of light is used which greatly attenuates light due to bilirubin (440 nm) or glucose (1060 nm), then the bilirubin or glucose value may also be determined. Also how to determine the hematocrit with a two step DC analysis technique is provided. Then a pulse wave is not required, so this method may be utilized in states of low blood pressure or low blood flow.

The invention relates to estimation of a patient's propensity to suffer from symptomatic hypotension during extracorporeal blood treatment. An electromagnetic test signal, which is applied over a thoracic region of the patient via at least one transmitter electrode. A result signal produced in response to the test signal is received via at least one receiver electrode on the patient. A test parameter is derived based on the result signal. The test parameter expresses a fluid status of the thoracic region of the patient, and it is determined whether the test parameter fulfills an alarm criterion. If the test parameter fulfills an alarm criteria, an alarm signal is generated. This signal indicates that the patient is hypotension prone, and that appropriate measures should be taken.

The invention relates to a piezoelectric sensor for the improved measurement of mechanical variables such as force, pressure or measurement variables which are derived there from, particularly a PVDF film sensor having an improved sensitivity and temperature stability of the measurement signal for pressure measurements that vary in time and/or space, and for the one- and two-dimensional determination of the position and propagation velocity of pressure fluctuations and pressure waves with a single measurement sensor at a measurement location. A preferred field of application of the invention is the non-invasive, low strain and continuous measurement of the pulse rate and the systolic and diastolic blood pressure of humans and animals by determining the velocity and the signal form of the pulse waves. The object of the invention is to allow the measurements of the blood pressure and the pulse rate, for example even in the case of emergency patients having only a very low blood pressure and patients having circulatory disorders in the extremities, for example patients which have developed diabetes or the “smoker's leg”, by using only one sensor at a measurement location due to the improved measurement sensitivity of the piezoelectric sensor, with the result that the continuous application of a pressurized jacket for continuously measuring and monitoring the blood pressure is not necessary. The present invention solves this problem in that a plurality of parallel strips of a piezoelectric material (1) are associated as a measurement membrane in the pressure sensor according to the invention with a sensor base body (4) in such a manner that the parallel strips are tension preloaded in a one-dimensional and elastic manner in the direction of the piezo dipole orientation and that an empty cavity (5) is provided between the tension preloaded piezoelectric sensor material (1) in the measurement portion and the sensor base body (4), formed by a recess/cutout.

An apparatus and method of temporarily replacing the function of the left ventricle in a patient whose heart is severely injured and is unable to maintain a systemic arterial pressure adequate to support the inside walls of patient's aorta, the method comprising a removable pressurizable support means having an external profile which is expandable to fit firmly against the inside wall of the aorta of a patient, wherein the external profile of the pressurizable support means presents a central opening that allows blood to flow through the aorta. The pressurizable support means can both support and expand the aorta under low blood pressure to assist the drawing of blood from the left ventricle. The central opening also allows for the placement of a blood flow control means. The blood flow control means can comprise a pumping balloon and a proximal blocking balloon, the two members pressurized and depressurized in opposition within the aorta of a patient to simulate systole and diastole of a healthy heart. The pumping balloon has a pressurized pumping position that is engaged while the proximal blocking balloon is in a depressurized deflated position.
