The unique design of the motion artifact rejection system allows for easy integration into new or existing pulse oximeters. Institute engineers have continued to improve the accuracy and capabilities of the SwRI oscillometric blood pressure monitoring system. The SwRI-developed methods have been incorporated into medical monitoring products expected to reach the market following regulatory approval. The Institute's extensive bioengineering test facilities provide for a wide range of laboratory and bench-top biocompatibility tests. Here, a new oxygenator for a cardiopulmonary bypass system is being tested in a flow loop using human blood.
Blood pressure measured on the arm or wrist is different from the blood pressure at the heart.
Alterations in blood pressure are produced by the mechanics of wave propagation through the arteries and, as a result, peripheral blood pressures do not always accurately represent a patient's cardiovascular state. SwRI engineers have developed methods for noninvasively determining the central aortic blood pressure. Using mathematical models of the cardiovascular system to correct radial blood pressure signals, these innovative methods are able to produce accurate, continuous estimates of aortic pressure. Because ejection systems are designed for the average male aviator, it is possible that females could be more prone to injury during ejection because of their smaller physical size. Uncertainties, whether due to the systematic size difference between males and females or to the inherent randomness in configuration of the spinal components or physical properties, will be simulated by analyzing the model using SwRI-developed advanced probabilistic analysis techniques.
