97 results about "Vascular health" patented technology

Vascular health encompasses the health of your vascular, or blood vessel, systems of your body. Maintaining a healthy condition of your arteries and veins will help ensure you avoid developing vascular diseases as you age. Check out our tips below on improving your circulation and overall vascular health.

Method and apparatus including altimeter and accelerometers for determining work performed by an individual

Method and calculations determine an individual's, or several individuals' simultaneous rates of oxygen consumption, maximum rates of oxygen consumption, heart rates, calorie expenditures, and METS (multiples of metabolic resting rate) in order to determine the amounts of work that is performed by the individual's body. A heart monitor measures the heart rate, and an accelerometer measures the acceleration of the body along one or more axes. An altimeter measures change in altitude, a glucose monitor measures glucose in tissue and blood, and thermometers, thermistors, or thermocouples measure body temperature. Data including body fat and blood pressure measurements are stored locally and transferred to a processor for calculation of the rate of physiological energy expenditure. Certain cardiovascular parameters are mathematically determined. Comparison of each axis response to the individual's moment can be used to identify the type of activity performed and the information may be used to accurately calculate total energy expenditure for each physical activity. Energy expenditure may be calculated by assigning a separate proportionality coefficient to each axis and tabulating the resulting filtered dynamic acceleration over time, or by comparison with previously predetermined expenditures for each activity type. A comparison of total energy expenditure from the current activity is compared with expenditure from a previous activity, or with a baseline expenditure rate to assess the level of current expenditure. A measure of the individual's cardio-vascular health may be obtained by monitoring the heart's responses to various types of activity and to total energy expended.

Dosage forms useful for modifying conditions and functions associated with hearing loss and/or tinnitus

The invention defines interdependent biofactors and biomolecules, and clinically useful formulations that are comprised of them. The active agents are demonstrated to be complementary in their physiologic functions especially as these relate to the quenching of free radicals and to the support of endothelial physiology, the reduction of hyperinsulinemia and improvements in vascular health. The active components of the invention are selected for inclusion in precise combinations specifically because they improve these various conditions and physiological functions, and by so doing reduce a variety of risks associated with hearing loss and tinnitus. The resulting enhancement of general systemic vascular health, improvement in local VIIIth nerve vascular health, modulation of conditions surrounding blood fluid dynamics, the consequences of hyperinsulinemia, and improvements in free radical defenses, all reduce the potential for cochlear hair cell death and VIIIth nerve atrophy, and the hearing loss and possible deafness that accompany them.

Noninvasive determination of cardiac health and other functional states and trends for human physiological systems

This document describes the assessment of human physiological systems in a manner that can be applied throughout the population. Various noninvasive sensors (including wearable, passive contact and noncontact sensors) may be integrated into the furniture of a person's home (including a mat, a toilet-seat, a mirror and a bathtub). They can be used to detect vitals and other parameters and combined with mathematical models to assess the functional state of physiological systems. For example, the health of the cardiovascular system is ultimately determined by organ blood perfusion and molecular gas exchange. In lieu of measuring these functional metrics directly, noninvasive sensors are used to monitor cardiac pressures and volumes, along with pressure transit through the vascular to quantify cardiovascular health, presenting little if any risk to the person and are simple and easy to use. In particular, cardiac pressure-volume loops are determined at different points in time and a health trend for the physiological system is determined based thereon.
